The function of this valve is basically the same as that of valve type 2FRM6B~3X/~R. 2FRM6A~3X/~RÂ
Flow control valve 2FRM6B~3X/~M
Flow control valve of type 2FRM is two-way flow control valve, used forÂ
maintaining a constant flow and is independent of pressure and temperature. itÂ
consists of housing(1), knob rotary(2), orifice(3), pressure compensator(4), Â
optional check valve(9).
Flow from A to B is throttled at throttle channel (5). Throttle cross-section isÂ
varied by turning the knob rotary(2). To avoid effects of pressure at port B onÂ
constant flow, a compensator (4) is fitted. Spring (6) separately compress theÂ
compensator (4) and orifice (3) tightly.
Spring (6) compresses the compensator (4) tightly to maintain it open when no fluid flows through theÂ
valve. Once the fluid flows across the valve, the pressure in port A applies a force to pressureÂ
compensator (4) via orifice (7).The pressure compensator (4) moves into the compensating positionÂ
until the forces is balanced. If the pressure in port A rises, the compensator (4) moves to its closingÂ
direction until force is balanced again. Â Due to the compensator (4) continuous action, a constant flowÂ
is obtained.
pressure compensator (4) of this type of valve is connected with port P(11) so that pressureÂ
compensator(4) can be closed by external pressure. Any pressure in port P via orifice (10) can makeÂ
the compensator (4) closed against the force of compression spring (6) .When the directional valveÂ
(12) acts, fluid flows  from P to B, control is achieved as type  2FRM6B.
This flow control valve with external pressure compensator which can be closed only works asÂ
controlling the inlet flow.
