FAR1-10 - Flow Regulator

Fully adjustable, pressure compensated with free reverse flow

1-38 L/min (0.25-10 USgpm) • 310 bar (4500 psi)

Operation

Flow into the inlet of the valve

passes through the adjustable

orifice and out of the regulated

port. The pressure drop across

the orifice is sensed on the

regulating sleeve and produces

a force which, at the

Performance Data

Typical Flow Regulation

Cartridge only

required flow rate, overcomes

the spring force. The resultant

movement of the sleeve

regulates the flow by closing

the radial valve ports.

The inbuilt check allows free

return of flow (2 to 1).

Features

Cartridge construction gives

versatility of application. A

valve may be fitted into a

line body, a custom designed

Hydraulic Integrated Circuit or

directly into a cylinder or other

actuator. Leakproof adjust

screw gives easy, accurate

adjustment to required flow

setting. Hardened and ground

working parts give accurate

flow control and long working

life.

Description

This is a two-port, restrictive

flow regulator with a built in

free flow check valve. Typical

uses include the control of

actuator speed by regulating

the flow into or out of the

actuator (meter-in or

meter-out).

The flow (and actuator speed)

will be largely independent

of the load and the pressure

conditions. If used to restrict

flow from a fixed supply, for

example a standard gear or

piston pump, the valve will

pass the required flow and any

surplus flow will normally pass

over the system relief valve.

Note: To reset scale and

knob to an optimum viewing

position:

1. Loosen the set screw

2. Rotate zero point on scale

to a desired orientation.

3. Align mark on knob with

zero on scale.

4. Tighten the set screw

rmly.

Note: To change the setting:

1. Loosen the set screw

2. Loosen jamnut while

holding the knob steady, or

move the knob along the

axis slightly.

3. Turn adjusting screw (jam

nut and knob will turn at the

same time).

4. At the new adjusting screw

position, tighten jamnut

rmly while holding the

knob steady, or move the

knob along the axis slightly.

5. Tighten the set screw
