9800 Pilot Operated Pressure/Vacuum Relief Valve
On line Service

The 9800 series pilot operated relief valve has two principal advantages over other types of relief valves:1. It is bubble tight to set pressure.2. It is fully open at less than 10% above set pressure.These characteristics permit an operating pressure nearer to the maximum allowable working pressure of the tank. High operating pressures reduce evaporation and total venting volume, thereby reducing product loss and cost of processing emissions.
