2-way flow control valves are flow valves (throttle valves) with a built-in pressure compensator. The valves automatically regulate an adjustable volume flow regardless of pressure changes in the supply or discharge line. They can be installed on the supply or discharge side of the consumer.
FEATURES
Remote controllable, programmable
Analog control means: The stepper motor is controlled by
our control unit via an analog input signal (0-10 V; 0-20 MA)
Stepper motor position is monitored with a feedback potentiometer
Failsafe behavior: Valve retains the last position it was in if the power supply fails
No electrical temperature drift
Minimum actuation time 1.5 sec.
Resolution approx. 0.25%
Volume flow signal function: Linear
7 nominal setting volume flow ranges
Hole patterns according to Schiedrum's in-house standard
Installation on connection plates with pipe connections or control block
With bypass check valve
Standard sealing material Buna N (NBR), other materials possible
For volume flow control in both flow directions,
Volume flow rectifier intermediate plate valves type 71 are available
