DPWC Series | Dual Plate
Wafer Check Valve
C&C Industries
The C&C DPWC Series Dual Plate Wafer Check Valve is a compact, high-performance solution designed for efficient backflow prevention in pipeline and process systems. Built to API 594 standards, it provides reliable operation with minimal pressure loss and fast response to changing flow conditions.
Its dual plate, spring-assisted design allows for rapid closure, reducing the risk of backflow and minimizing water hammer compared to traditional swing check valves. The retainerless body construction enhances safety by eliminating potential leak paths, making it well suited for hazardous and critical service environments.
With a full port design, metal-to-metal sealing, and Stellite-faced seating surfaces, the DPWC Series delivers long service life, durability, and consistent performance across a wide range of operating conditions.

PERFORMANCE ADVANTAGES
Why the DPWC Series Performs Where It Counts
FAST CLOSURE REDUCES WATER HAMMER RISK
The dual plate, spring-assisted design allows the valve to close quickly when flow reverses. This reduces slam potential and helps protect piping systems and equipment from pressure surges.
COMPACT DESIGN FOR SPACE & WEIGHT SAVINGS
Wafer-style construction significantly reduces face-to-face length and overall weight compared to traditional check valves. This simplifies installation, reduces structural loading, and improves system flexibility.
RETAINERLESS DESIGN FOR ENHANCED SAFETY
Unlike traditional designs, the retainerless body eliminates external penetration points. In hazardous or corrosive applications, this reduces the risk of leakage through the valve body and improves overall system integrity.
LOW CRACKING PRESSURE FOR
RESPONSIVE OPERATION
With cracking pressures as low as 0.1–0.2 PSI depending on size, the valve responds quickly to flow changes, ensuring efficient operation even in low-pressure systems.
