Flow control valves are 2-way flow control valves. Thanks to cooperation with Rexroth twice from 1979, Huade has incorporated cutting-edge technology from Rexroth. The quality of Huade® flow control valves can match that of first-tier international brands, and the price of the products is even lower. The series of flow control valves can be used in the steering gear hydraulic system. Huade Hydraulic own a huge customers in the marine industry.

Features:
▶ Porting pattern to DIN 24 340,from A,ISO 4401 and CETOP - RP 121H
▶ Pressure compensator stroke limiter, optional
▶ Mechanical operation
▶ Start-up jump reduction
▶ Flow control in both directions using a rectifier sandwich plate
Application:
Flow control valves 2FRM 10 are used to maintain a flow constant independently of pressure and temperature.
The valves 2FRM 10 basically consist of the housing (1), orifice bushing(3), pressure compensator (4) with optional stroke limiter,check valve(5), adjustment element (2).
The flow from channel A to channel B is throttle at the orifice (6). In order to maintain the flow across the orifice constant, a pressure compensator is connected upstream of the orifice (6). The flow is maintained largely independent of temperature due to the orifice design. Free return flow from channel B to channel A is directed via the check valve (5).The flow is only controlled from A to B. In order to control the flows in both directions a rectifier sandwich plate type Z4S can be installed below the flow control valve.
