Dual plate check valve manufacturers in India

Speciality Valves is a top Dual plate check valve manufacturers in India, providing robust, compact, and high-performance check valves for reliable flow control and backflow prevention in piping systems. Our dual plate check valves are made in accordance with international standards, guaranteeing long-term working safety and efficiency.

Why Dual Plate Check Valves Are Needed?

Backflow in fluid systems can lead to equipment failure, system inefficiency, and contamination. Dual plate check valves are essential to preventing reverse flow automatically without the aid of external actuation. They are especially used in high-temperature and high-pressure applications where consistent performance is not an option.

Key Components of Dual Plate Check Valve:

Valve Body: Often constructed from cast iron, stainless steel, or other high-strength alloys

Dual Plates (Discs): Two spring-loaded plates for forward flow and instant closure in reverse flow

Spring Mechanism: Provides rapid and positive closure

Stop Pin & Hinge Pin: Facilitate the movement and alignment of the plates

Seat Rings: Ensure leak-tight sealing

Working of Dual Plate Check Valve:

When fluid flows in the direction of forward flow, pressure opens the twin plates so that there is unobstructed flow. In case of reverse flow or pressure drop, the torsion springs immediately push the plates towards each other, closing the valve and avoiding backflow. This is done with quick action to avoid water hammer and safeguard downstream equipment.
