White Knight/iPolymer iPolymer Drain Valve (DV) is a large orifice valve capable of handling large volumes of corrosive fluids via an all non-metallic wetted surface.
The valve body components are manufactured from PVDF to maximize performance in ultrapure and harsh chemical environments.
PVDF models are available with EPDM, Viton or Kalrez O-rings. Cost efficient PVC or Polypropylene models are available with EPDM and Viton O-rings. The valves are available in 2, 3 and 4-way configurations with each port operating independently. The “DV” can be operated either by air to open/air to close or by spring return.
