ភាសាខ្មែរDHC Dual Plate Check Valve – Korea
The DHC Dual Plate Check Valve (butterfly-type check valve) is an essential component in many modern industrial systems, ensuring one-way flow and preventing reverse flow that could damage equipment. Manufactured by DHC – Korea, this product is trusted for its stable quality and competitive price.
Technical Features
Structure
- Consists of two semi-circular plates mounted on a central spring-loaded shaft.
- When fluid flows, the plates open. When the flow stops or reverses, the spring closes the plates, preventing backflow.
- Main materials: epoxy-coated ductile iron body, stainless steel or zinc-plated steel plates and shaft.
Design
- Wafer type (sandwiched installation) – slim, compact, easy to install between flanges.
- Space-saving, ideal for systems with limited installation room.
- Cast markings on the body: DN size (e.g. DN50, DN80), PN rating (e.g. PN10, PN16), and flow direction arrow.
