Application:
Flow control valve, type 2FRM is a 2-way flow control valve, which is used for throttling and is not affected by pressure and temperature.
The 2-way flow control valve 2FRM mainly consists of housing(1), setting element(2), orifice(3), pressure compensator (4) optionally with stroke limiter as well as check valve(5) and is used for the throttling of a flow at low pressure and temperature dependency.
The throttling cross section is set by the rotation of the curve bolt(7).To keep the flow constant independent from the pressure at the throttling point(8) a pressure compensator (4)is connected. The temperate independence is the result of the throttling point being constructed as an orifice.
The free flow return from B to A is via the check valve(5).
In order to reach a controlled through flow of the valve in either direction there is the possibility to install a rectifier sandwich plate type Z4S below the flow control valve.
