Single plate check valve manufacturers in India

Speciality Valve is a renowned Single plate check valve manufacturers in India, producing small check valves that are reliable and economical and designed for use in a variety of applications in industries. Our single plate check valves are specifically designed to provide perfect backflow prevention with low pressure drop and seamless installation.

Why Required?

Single plate check valves are critical fittings in piping systems where flow direction must be regulated. They permit fluid to flow in one direction and automatically block reverse flow, safeguarding pumps, compressors, and pipelines against possible damage. Their compact design makes them perfect for use in applications with limited space.

Key Components of Single Plate Check Valve:

Body: Cast in stainless steel, carbon steel, or other alloy materials

Disc (Plate): One hinged disc that opens on flow and closes on backflow

Seat Ring: Provides leak-tight sealing

Spring (Optional): Helps for quicker disc closure to avoid water hammer

Hinge Pin: Facilitates disc motion

Working of Single Plate Check Valve:

The one plate check valve operates automatically by means of the force exerted by the passing medium. Forward flow fluid pressure displaces the disc to permit flow. Reverse flow causes the disc to swing back into the seat, preventing reverse travel and backflow. A spring is used in some designs for faster closure.
