lubricant divider valves

Application

The 1000 Series progressive divider valve distributes and proportions incoming oil or grease to bearing points. A typical divider valve consists of an inlet section, three to nine intermediate valve sections and an end section. One assembly can serve up to a maximum of 18 lubrication points.

Individual divider valve sections have a piston and built-in outlet check valves. Valve sections are offered in three output sizes. The discharge capacity of a valve section is determined by differing piston diameters in each valve section. Valve sections have two outlets located at either end (double outlet blocks) and a predefined volume of grease is delivered from each of the outlets during one valve cycle.

Application

The 3000 Series progressive divider valve distributes and proportions incoming oil or grease to bearing points.

A typical divider valve consists of an inlet section, three to ten intermediate valve sections and an end section. One assembly can serve up to a maximum of 20 lubrication points.

Individual divider valve sections have a piston and built-in outlet check valves. Divider valves are offered in six output sizes. The discharge capacity of a valve section is determined by differing piston diameters in the individual valve sections.

Application

DD Valves are dual-line divider valves that are hydraulically operated. They will deliver either oil or grease, and each pair of outlets can be adjusted to discharge a predefined volume of grease and are fitted with motion indicators. Each pair of outlets can be converted to a single outlet by the removal of an internal grub screw. For example, a 4-way divider valve can serve from four to eight lubrication points.

DD Valves can be supplied in several basic discharge capacities and are available in 1-, 2-, 3- or 4-way valves.

Application

Modular dual-line divider valves are ideal for applications where a varying range of lubricant quantities is needed from a single divider valve. All the moving parts are in the removable upper section. The removable upper section mounts onto a manifold with 2-20 outlets. The DDM/SDM upper valve sections can be replaced individually, therefore it is not necessary to change an entire divider valve in the event of a malfunction.

Features

• Each module can be individually adjusted within its capacity to suit the bearing requirements (adjusts a pair of outlets).
• All moving points are contained in the upper valve section.
• A malfunctioning upper valve section can be changed in minutes, reducing maintenance time and costs.
• Positive hydraulic operation - within design limitations, these valve assemblies can be mounted long distances from the central pumping station.
• Visual indicator showing operation of each upper valve section.
• Body protected by corrosion resistant electroplating.

Application

The DM divider valves are hydraulically operated and will deliver either oil or grease, and each pair of outlets can be adjusted to discharge a predefined volume of grease and are fitted with motion indicators. DM divider valves always have one discharge port per pair of outlets located on the bottom of the divider valve.

DM divider valves can be supplied in several basic discharge capacities and are available in 1-, 2-, 3- or 4-way valves.

Application

The DX Valve is available with varying number of outlets for use with any conventional portable type, lubrication gun to serve a limited number of lubrication points where the installation of a complete centralised lubrication system would not be justified. This unit is widely used for the lubrication of materials handling equipment, trucks, presses, machine tools and large or small pieces of equipment with isolated groups of lubrication points.

These systems provide low cost centralised lubrication to small groups of isolated lubrication points, i.e. 4 to 12 lubrication points.

This system offers the following advantages:

• Reduction in the number of grease nipple connections required
• Lubrication from a safe, convenient central point
• Control of quantity of lubricant going to the lubrication points (the amount delivered to each pair of lubrication points is adjustable).

Application

The FD Series divider valves are designed for use in series progressive oil and grease lubrication systems. They are of two piece, steel construction with viton O-ring seals. FD valves will serve 2, 3, 4 or 6 lubrication points. The 2, 3 and 4 point divider valves require 0.08 cubic inches to complete one full cycle. An FD-6 divider valve requires 0.06 cubic inches to complete one full cycle.

Application

The M2500 Series divider valves are designed for use in series progressive oil and grease lubrication systems. Modular construction makes these divider valves easy to install, modify and maintain, without removing any tubing.

As the lubricant is pumped into the divider valve, the internal pistons will cycle in a pre-arranged sequence. An indicator pin can be supplied on one of the valve sections to provide visual indication that the divider is cycling. Furthermore, a limit switch can be attached to the indicator pin to provide an electrical feedback that the divider is cycling.

Up to 20 lubrication points can be lubricated from one divider valve assembly. Series progressive systems can consist of a master divider valve assembly, supplying lubricant to several slave divider valve assemblies. This permits the lubrication of a hundred or more lubrication points from one master divider valve assembly with one pumping unit. Upper valve sections have differing piston diameters and can be configured as single outlet or twin outlet, thus making the system capable of servicing lubrication points with large variances of volume requirements.

Application

The PVB series divider valves are applied in small progressive lubrication systems which provide a cost saving and efficient solution for lubrication points with relatively low pressure and small volume requirements. Used for machine tools and processing machinery, presses of every type, plastic and paper processing machines, textile machines, printing and packaging machinery, etc.

Product Features

Design and Function

The divider valves are available in sizes ranging from 6 to 20 outlets. Valve sections can be converted from twin outlets to single outlets with use of fittings to alter the internal porting of the valve section.

Lubricant pumped into the divider valve is directed through the valve via internal porting and the pistons in each valve section. The pistons deliver a metered amount of lubricant to each lubrication point. The divider valve can be supplied with an indicator pin to visually check the cycling of the divider valve. A limit switch can also be attached to the indicator pin to monitor the system electrically.

Application

The ZP Series divider valves are used to divide and meter lubricant in total loss centralised lubrication systems (oil, liquid grease and grease) and in oil recirculation systems suitable for small, medium and large machine applications.

Product Features

• Progressive divider
• Electronic monitoring possible
• Grease, liquid grease and oil

Design and Function

The divider valves are available in sizes ranging from 6 to 20 outlets. Valve sections can be converted from twin outlets to single outlets with use of fittings to alter the internal porting of the valve section.

Lubricant pumped into the divider valve is directed through the valve via internal porting and the pistons in each valve section. The pistons deliver a metered amount of lubricant to each lubrication point. The divider valve can be supplied with an indicator pin to visually check the cycling of the divider valve. A limit switch can also be attached to the indicator pin to monitor the system electrically.

Function

The ZP divider valve series consists of several individual segments that are bolted together and sealed against each other.

Depending on the arrangement within the divider valve, the following segment types are available:

• Inlet - or A-segment
• Intermediate - or M-segment
• End - or E-segment

The ZP divider valve series is designed to divide the lubricant volume (oil or grease) received under pressure into metered volumes and to deliver the lubricant to each point with up to a possible 24 outlets. This is achieved due to pistons which are moved by the lubricant being fed under pressure, through the internal porting of the divider valve.

The divider valve will cycle continuously while the lubricant is being fed to the divider valve under pressure.

The divider valves are equipped with outlet check valves which ensure positive displacement of the lubricant to the lubrication point, irrespective of the back pressure at the lubrication point. An indicator pin can be supplied on one of the valve sections for visual indication, or by attaching a limit switch to achieve electrical monitoring of the effective cycling of the divider valve.

Application

The ZV divider valve series is used for dual-line centralised lubrication systems for grease and for oil. The function of the ZV divider valve series is to deliver a metered amount of lubricant to any number of lubrication points, irrespective of the back pressures at the respective lubrication points.

Product Features

• Dual-line divider valve (type F with flange plate)
• Grease and oil
• Material: steel

Design

The ZV divider valve series is a block type design, and is available with different ranges of volume output. Each divider valve has two threaded holes (3⁄8 inch BSP) on two faces for the connection of the two main lines in and out of the divider valve. The outlet ports (¼ inch BSP) are situated on the other two faces of the divider valve and there can be 2 to 8 outlets, depending on the size of the divider valve being used.

Function

The ZV divider valve series has one metering piston and one control piston for each pair of outlets. One main line is pressurised, while the other main line is relieved of pressure. The outlets that are closest to the pressurised main line will deliver lubricant to the lubrication points. As a result, an operating cycle always includes two lubricating strokes.

A dual-line system operates with two main lines. One line is pressurised and one half of the divider valve is cycled, while the other main line is depressurised. An end of line switch senses a pre-set pressure, which is the signal for a change-over to be activated, and the line that was depressurised now becomes the pressurised line and the second half of the divider valve is cycled. The previously pressurised line is now depressurised . The second end of line pressure switch is activated and on activation of the pressure switch the overall system goes into a pause period.
