Walchem Automatic Degassing Valve for E Series Pumps, ADV-VC-7
Description
- Specifically designed for suction lift applications
Use this valve with Walchem E-series metering pumps to prevent gas lock caused by off-gassing chemicals like bleach or hydrogen peroxide. Valve uses the pump's suction stroke, along with gravity, to create subtle liquid pullback into the pump head. This allows trapped gas to vent out before reaching the discharge check valve. Dual check valve system allows only a limited amount of vented gas and fluid to return to the supply tank, without affecting the pump's pressure capabilities.
Field conversion is easy—just install the valve between the pump head and existing manual air vent valve. Manual air vent functionality remains unchanged. Wetted materials: PVC housing, FKM seals, titanium separation pin.
Note: Pump output will inherently decrease by roughly 15 to 20% due to the liquid returning to the tank during operation.
- MFR #: ADV-VC-7
- Housing: PVC with FKM seats and seals
- Separation pin: titanium
- Vent connection: 3/8" OD
