overview
2L Dual Plate Check Valve is an all-purpose non-return valve type of valve with enhanced sealing efficiency and is much lighter in weight and smaller in size compared to a conventional swing check valve. Dual Plate Check Valve,
widely known as DPCV comes with both Soft and metal-to-metal seating arrangements.
DPCV are easy to handle and install in any piping system with no constraints.
Special Features
- The design complies with API 6D, API 594
- Retainer-less design
- Two independent seats provide consistent sealing even in uneven flow
