Balanced Bellows Relief Valves
Balanced Bellows Relief Valve
Material:
Body: Commonly made from stainless steel, carbon steel, or alloy steel, selected for their strength, durability, and resistance to corrosion in demanding environments. Stainless steel is often preferred for its superior corrosion resistance, especially in high-temperature and aggressive fluid systems.
Bellows: The bellows component is typically made from stainless steel, Inconel, or Hastelloy, which are highly resistant to high temperatures, pressure, and corrosive substances.
Seals: Seals are made from materials like Viton, PTFE, or EPDM, which offer chemical resistance and ensure a tight seal under high-pressure conditions.
Size (Nominal Pipe Diameter):
Typically ranges from 1″ to 6″, but larger sizes can be custom-designed depending on the application and flow capacity 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.
