Types Of Stainless Steel Check Valves

Types Of Stainless Steel Check Valves
May 16, 2024

Stainless steel or metal check valves come in various types, each designed to suit specific applications and preferences. 

Here are their different types for your reference.

Different Types of Stainless Steel Check Valves

Whether it’s the swinging motion of the swing check valve, the lift action of the lift check valve, or the compact design of the wafer check valve, choosing the right tape  depends on the requirements of the system and the desired performance characteristics.

1. Stainless steel swing check valve

The swing check valve has a hinged disc that swings freely to allow fluid flow in one direction. When the flow stops or reverses, the disc swings back to its closed position, preventing backflow.

2. Lift check valve

Similar to the swing check valve, the lift check valve has a disc, but instead of swinging, it lifts off the seat to permit fluid flow. It provides a slightly better seal than the swing check valve.

3. Ball check valve

The ball check valve uses a ball-shaped disc to control flow. When the fluid pushes against the ball, it lifts, allowing flow. When the flow stops, the ball drops back into place, preventing backflow.

4. Dual plate check valve

The dual plate check valve has two plates that open and close simultaneously on a hinge. It offers quick closure, reduces the chances of water hammer, and is often more compact than other designs.

5. Stainless steel inline check valve

Designed for easy installation directly in a pipeline. It allows fluid to flow in one direction and prevents backflow when the flow stops.

6. Wafer check valve

A lightweight and compact check valve designed to fit between flanges without the need for additional gaskets. It is suitable for applications with limited space.

7. Silent check valve

Specifically designed to minimize noise during operation. It prevents water hammer effects and reduces the slamming sound often associated with traditional check valves.

8. Stainless steel spring check valve

Equipped with a spring that assists in closing the valve quickly. This feature reduces the chances of water hammer and enhances the overall performance of the valve.

9. Stop check valve

Combines features of a globe valve and a check valve. It can be locked in the closed position, providing additional control over fluid flow.

10. Tilting disc check valve

Instead of swinging or lifting, the disc tilts to open and close. This design offers a faster response to changes in flow conditions and helps reduce the potential for water hammer.

11. 2 inch stainless steel check valve

A 2-inch stainless steel check valve is a plumbing component with 2-inch diameter ports, made of stainless steel for corrosion resistance. 

It functions to allow one-way fluid flow, preventing reverse flow. 

This valve is commonly used in various applications where a 2-inch size is appropriate for the plumbing or piping system.
