ភាសាខ្មែរDHC Dual Plate Check Valve
The DHC Dual Plate Check Valve is an essential component in many modern industrial systems. It controls one-way flow and prevents reverse flow, which could otherwise damage the system. Manufactured by DHC – Korea, this product is highly regarded for its reliable quality and reasonable price.
Technical Characteristics
Structure:
- The valve consists of two semi-circular discs mounted on a central spring-loaded shaft.
When the flow passes through, the discs open; when the flow stops or reverses, the spring automatically closes the discs, preventing backflow. - Main materials: Body made of epoxy-coated cast iron (blue); discs and shaft are typically made of stainless steel or galvanised steel.

Design:
- Wafer type (clamped connection): Slim, compact, and easy to install between flanges.
- Installed between pipeline flanges, it requires little space—ideal for confined systems.
- The valve body is embossed with markings such as DN50, DN80 (nominal diameter), PN10, PN16 (pressure rating and connection standard), and a flow direction arrow.
