FAR1-16 - Flow Regulator

Fully adjustable, pressure compensated with free reverse flow

3.8-114 L/min (1-30 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 required

flow rate, overcomes

Typical Flow Regulation

Cartridge only

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.
