Piston Check Valve
Piston Check Valve
Material:
Body: Typically made from stainless steel, carbon steel, cast iron, or brass, depending on the application’s pressure, fluid type, and environmental conditions. Stainless steel is commonly used for its strength, corrosion resistance, and durability.
Piston and Seat: The piston and seat are often made from stainless steel or alloy steel, ensuring wear resistance and reliable operation in high-pressure applications.
Seals: The seals are typically made from rubber, Viton, or EPDM, providing a tight shutoff and preventing leakage.
Size (Nominal Pipe Diameter):
Common sizes range from 2″ to 12″, but can be customized for larger diameters depending on the system requirements.
Spring Check Valve
Spring Check Valve
Material:
Body: Commonly made from stainless steel, carbon steel, or brass, depending on the application’s fluid type, pressure, and temperature. Stainless steel is often used for its corrosion resistance and durability in harsh environments.
Internal Components: The spring and seat are usually made from stainless steel or alloy steel for strength and resistance to wear. The seal may be made from rubber, Viton, or EPDM, providing a reliable shutoff.
Spring: The spring itself is typically made of stainless steel to ensure long-term durability and resistance to corrosion.
Size (Nominal Pipe Diameter):
Common sizes range from 1/4″ to 6″. Larger sizes can be made based on specific system requirements and flow conditions.
Nozzle Check Valve
Nozzle Check Valve
Material:
Body: Typically made from stainless steel, cast iron, or brass, depending on the fluid type and pressure requirements. Stainless steel is often preferred for its corrosion resistance and durability in harsh conditions.
Internal Components: The internal components, including the disc and spring, are usually made from stainless steel or alloy steel, ensuring strength and resistance to wear.
Seals: Rubber, Viton, or EPDM seals are commonly used to provide a tight shutoff and prevent leaks.
