General:
The flow control valve type 2 FRM is a 2-way flow control valve.
It is used for maintaining a contant flow, independent of pres-
sure and temperature.The valve basically comprises of housing
(1), rotary knob (2), orifice (3),pressure compensator (4) and an
optional check valve.

Type 2FRM 6 A..-20B/..R
The function of this valve is basically the same as that of valve type 2FRM 6 B..-20B/..M.
However, this type of flow control valve is provided with an external port permitting the pressure compensator (4)
to be connected to via port P(11) . The external pressure acting in port P(11) via orifice (10)holds pressure
compensator (4) closed against the force of compression spring (6). When the connected directional valve (9) is
actuated to permit flow from P to B,closed loop control is achieved as
with type 2 FRM 6 B. Thus a jump on start-up is avoided.
This version with external closing of the compensator may only be used
for meter-in control.
Free return flow from port B to A is via check valve (8).

Attention!
The pressure loss from P (at the inlet of the directional valve) to A (at the inlet of the flow control valve) is noticeable at low flows.
