Hydraulic Quick-Vent Valves
Pneu-Hydro hydraulic quick-vent valves are designed to be placed in the line between a control valve and actuator. When control pressure is applied, the internal poppet closes the quick-vent port and directs flow through the outlet to the actuator. Upon release of pressure, the poppet’s internal check closes and the poppet is lifted off the vent seat. The large capacity of the outlet/vent passage permits rapid flow from the actuator.
The valve is constructed of corrosion resistant materials in accordance with NACE MR-01-75.
