Vertical Lift Check Valve
When backflow prevention is mission-critical in your vertical pipelines, you need a valve engineered for uncompromised performance and durability. Our Stainless Steel Flanged Vertical Lift Check Valve is your go-to solution for preventing reverse flow in process lines handling water, oil, steam, or aggressive chemicals.
Built for vertical upward flow only, this lift-type non-return valve combines precise engineering with long-lasting stainless steel construction to ensure reliable sealing under a wide range of industrial applications.
Whether you need 1 piece or more, we can deliver tested, performance-qualified products on time.
Description
Designed to operate without external actuation, the vertical lift check valve uses gravity and a spring-loaded disc to allow forward flow and automatically seal against reverse flow. The disc moves vertically within the valve body and seats tightly when back pressure occurs, minimizing wear and preventing water hammer.
This flanged check valve is made of SS304 or SS316 stainless steel, making it ideal for corrosive media, hygienic processes, or outdoor installations. It’s designed in accordance with ASME, API, and DIN standards, ensuring seamless integration into your piping systems.
Whether you are replacing an existing check valve or specifying components for a new installation, this stainless steel vertical check valve offers performance you can trust.
