Frequently Asked Questions
Everything you need to know about double eccentric butterfly valves, including design features, materials, applications and performance.
What is a Stainless Steel Lift Type Wafer Check Valve?
A Stainless Steel Lift Type Wafer Check Valve is an automatic non-return valve designed to prevent reverse flow. The spring-loaded disc opens with forward flow and closes when the flow stops or reverses.
How does a spring-loaded lift check valve work?
The disc is lifted by the pressure of the flowing medium. When the flow decreases or reverses, the spring pushes the disc back onto the seat for quick and reliable closing.
What are the advantages of a spring-loaded design?
The spring-loaded design provides fast closing, helps reduce reverse flow and water hammer, and allows the valve to operate automatically without an external actuator.
Can the valve be installed in horizontal and vertical pipelines?
Installation orientation depends on the specific valve design and flow direction. The valve should be installed according to the manufacturer's specified flow direction and installation requirements.
What information is required for valve selection?
Key selection parameters include DN size, pressure rating, connection standard, medium, operating temperature, body and disc material, seat material, and installation orientation.
