What Are Bellows Valves?

Bellows valves are integral components in systems that handle gases and other fluids. A bellows is essentially a flexible, accordion-like component that expands and contracts to allow movement while maintaining a hermetic seal. The bellows is typically made from a durable, corrosion-resistant material like stainless steel, and its design enables it to withstand high pressures and temperatures.

When operated, bellows valves expand or contract to enable the valve to open or close. The bellows design allows for high-flow capacity while maintaining an optimized form factor. Bellows valves effectively control the flow of gases or other fluids within the system. They can be opened or closed to start or stop the flow, or partially opened to regulate the flow rate. The hermetic seal created by the bellows valves ensures that the fluid path is isolated from the atmosphere, preventing contamination and ensuring the purity of the gases. 

500 Series

The 500 Series manual and pneumatic operated bellows valves are designed with the industry's leading straight through full flow. This allows for maximum gas transfer through the main and lateral lines inside the fabrication facility. Fully functional from vacuum to 320 psig, these bellows valves are versatile for various operating conditions.
