Proportional Pressure Valves
Pilot Operated with Onboard Electronics
Mounting Surface NFPA R03 / D03
Max Pressure 5000 PSI
Max Flow Rate 13.2 gpm
Continental Hydraulics VER03MPG pilot operated proportional relief valves conform to NFPA R03 / D03 and ISO 6264:1998 mounting standards.
The VER03MPG valves have integral electronics on-board to maximize the valve’s performance. They are designed to modulate pressure in a hydraulic circuit directly proportional to the input command signal to the valve.
Command signals available are 0 -10 VDC and 4 – 20 mA.
The valve consists of a proportional pilot relief stage with on-board electronics and a main relief stage.The main stage has a spool which is held closed by a spring. System pressure acts on the opposite end of the spool opposing the spring force. When system pressure exceeds the spring force, the valve begins to open. The spring preload sets the minimum controlled pressure.
System pressure can be increased from minimum by increasing the pilot pressure which adds to the spring force. The spool will tend to close until the system pressure reaches its new setting.
There are four pressure ranges available: 70 bar, 140 bar, 210 bar and 350 bar with flow up to 13.2 gpm.
It is an internally piloted valve with three drain options – internal through T port, external through A port and external through Y port.
