Quick Dump Valves Our Quick Dump ("QD") Valves are designed to rapidly drain process tanks. Constructed from high-purity polymers, which are selected to meet your applications needs, our Quick Dump Valves are available in Polypropylene (POL) or Polyvinylidene Fluoride (PVDF). These valves are designed to be welded directly to the underside (bottom) of tanks. Our Quick Dump Valves are available configured with either O-Ring Seats or Domed Hard Seats. The Domed Hard Seat design prevents ponding/puddling of media on the valve piston and allows for a slight trickle of fluid. This plunger-style valve is very compact, while still configured with optional Air-to-Open/Spring-to-Close or Air-to-Open/Air-to-Close actuation.
