Dual Plate Wafer Check Valve

The Shoritsu DCV-W Series is a dual plate, wafer style check valve designed for efficient backflow prevention in pipelines where compact installation space, low pressure drop, and maintenance-free operation are required. Two spring-loaded plates open symmetrically under forward flow and close rapidly when flow stops or reverses, providing positive backflow prevention with minimal slam and water hammer risk.

The wafer body profile sits directly between pipeline flanges without the need for a full flanged valve body, significantly reducing face-to-face length and overall system weight compared to swing type check valves of equivalent size.

Features

• Dual plate spring-assisted design ensures rapid, positive closure when flow stops or reverses, significantly reducing slam and water hammer effects compared to single disc swing check valves
• Wafer body profile reduces face-to-face length and installation weight, making the DCV-W ideal for space-constrained pipeline installations and weight-sensitive applications
• Full stainless steel construction throughout body and disc provides excellent corrosion resistance and long service life across a wide range of liquid and gas pipeline fluids
• Viton seat material provides reliable sealing performance across a broad temperature and chemical compatibility range, suitable for both liquid and gas service
• Low pressure drop across the dual plate design maintains pipeline system efficiency and reduces energy consumption compared to conventional swing check valve configurations
