PRODUCT OVERVIEW
Double Door Check Valves
Compact dual plate check valves with spring-assisted closure.
- Pressure: 1.6 MPa, 2.5 MPa
- Connection type: Wafer
- Size range: DN50–DN600
Product Description
Double door check valves, also known as dual plate check valves, use two hinged plates within a compact body. The plates open with forward flow and spring assistance helps them return toward the closed position as the flow falls. They are suited to installations where a short face-to-face dimension and automatic reverse-flow protection are required.
