Pilot Operated Vent Valves

The Pilot Operated Model 5500 conservation pressure vent with pipe-away is intended for use where pressure relief is required and the relieving vapors must be piped away and not emitted into the atmosphere. May also be used for in-line vacuum relief.

Perfect for systems with backpressure situations in the header piping. Bubble tight up to setpoint and reaching full flow with only 1-2 % buildup. Extremely reliable and proven in the field.
