PV Modulating Control Device
This valve is used for fast and precise positioning of the hydraulic actuators of control valves. Along with the Proportional Valve Controller (PVR/SmarTrak) it converts the electrical signals into a flow of hydraulic fluid.
- Proportional valve to operate actuator.
- 3/2 blocking valve and two releaseable check valves in case of failure.
- Four flow sizes available.
- Two minimess connections to do performance checks and to relieve pressure in case of service.
- Designed for mineral oil and/or fire resistant hydraulic fluids.
