Valves Only, a top Alloy 20 check valve manufacturers in USA supplies high-quality, heavy-duty valves that ensure flawless flow control and long service life even under harsh conditions.
In backflow prevention and corrosion-resistant pipes, Alloy 20 check valves form part of the package. The valves are specifically made to operate in aggressive chemical environments, especially those with sulfuric acid.

What is Alloy 20 Check Valve?

A Check Valve of Alloy 20 is a check valve constructed using Alloy 20, nickel-iron-chromium alloy that exhibits extraordinary resistance to chloride-induced stress corrosion cracking, as well as to pitting and corrosion. For process protection as well as for equipment integrity, the check valve permits one way of flow with the opposite side closed to the flow.

Why It is Needed?

Check valves of Alloy 20 find their need in applications like:

Corrosive Media Handling: Particularly in petrochemical, chemical, and pharmaceutical use.
Backflow Prevention: For the safeguarding of compressors, pumps, and other sensitive equipment.
Low Maintenance Requirements: Suitable for use where regular maintenance is not permitted.
High Acid Attack Resistance: Suitable particularly in phosphoric, nitric, and sulfuric acid-bearing applications.

Key Components of Alloy 20 Check Valve:

Valve Body: It is constructed using Alloy 20, which is corrosion-resistant.
Disc or Ball: Depending on the pressure difference, it travels to allow or prevent flow.
Spring (optional): Assists in quicker closure in certain designs.
Seat: Provides a close seal to ensure no leaks.
End Connections: Socket weld, threaded, or flanged.

Working Mechanism:

The valve operates automatically. The disc or ball is lifted to allow passage when the fluid moves in the right direction. Pressure pushes the disc back to the seat when flow is reversed, closing off the valve and preventing backflow. Despite exposure to aggressive chemicals, the valve will be stable due to the application of Alloy 20.

Benefits of Using Alloy 20 Check Valve:

Better Corrosion Resistance: Ideal for use with highly corrosive or acidic fluids.
Longevity: Long lifespan with minimal wear.
Maintenance-Free Operation: Long-term reliability is assured by a simple design.
Protection from Backflow: Maintains system and equipment components.
High Temperature and Pressure Tolerance: Efficient in hostile environments.

Functions:

Prevents piping systems from flowing backward.
Prevents damage to sensitive equipment and pumps.
Helps maintain the effectiveness and safety of the procedure.
