Overview
Quick exhaust valves (QEV) increase pump efficiency by reducing the energy required to exhaust air from the pump. They reduce the risk of caustic chemicals escaping into sensitive environments by redirecting air into the pump containment area. QEVs are pump-mounted. They are made of UHMW-PE, and are available in four sizes. See specifications for pump compatibility.
Features & Benefits
- Non-metallic, corrosion resistant UHMW-PE extend QEV life and have no potential of ion contamination
- Auto-venting improves performance by reducing the energy required to exhaust air from the pump
- Reduce risk of caustic chemicals exhausting into sensitive areas by redirecting air into containment area
- Easy to install and service
- Minimal parts for durable design
- Integral muffler reduces size, noise and operator fatigue
- No maintenance required during two-year warranty
- Pump-mounted
