Alloy Dual Plate Check Valve

Alloy Dual Plate Check Valve

Middleeast Valve is reliable Supplier of Alloy Dual Plate Check Valve. We provide high-quality Alloy Dual Plate Check Valves, designed for effective backflow prevention in high-pressure and corrosive service. With a lightweight, compact design and high-performance alloy construction, these valves offer long-lasting, trouble-free service in demanding industrial systems.

 Definition

An Alloy Dual Plate Check Valve is a type of check valve that utilizes two spring-loaded discs (plates) to permit flow in the forward direction and against flow. Constructed from resistant alloy materials such as Inconel, Hastelloy, or Monel, it is best used in aggressive environments where regular materials are not durable enough.

 Major Components

1. Valve Body: Constructed from high-grade alloys for excellent strength and corrosion resistance.
2. Dual Plates (Discs): Open when flow goes forward and close firmly when flow reverses.
3. Torsion Spring: Provides fast and consistent plate closure.
4. Hinge Pin and Stop Pin: Guide and support the motion of the plate.
5. Seat Ring: Seals leak-tight when the plates are closed.

 Working Mechanism

As fluid flows in the direction of flow, the pressure tends to push the two plates apart. When flow is blocked or reversed, the two plates are snapped shut by the force of the torsion spring, thus eliminating backflow. The dual plate configuration reduces pressure drop and water hammer.

 Advantages

• Compact and light-weight design
• Corrosion, erosion, and high-temperature resistant
• Low pressure loss and energy-saving
• Rapid closure for water hammer elimination
• Long operating life with minimum maintenance

 Applications Commonly applied in:

1. Oil & Gas
2. Petrochemical
3. Desalination Plants
4. Marine and Offshore
5. Chemical Processing

 Why is it Needed?

It protects the system by avoiding reverse flow, equipment damage, and process interruption under corrosive and high-pressure situations.
