About Ptfe Lined Swing Check Valve

To render you with high flow rates at a low pressure drop, PTFE Lined Swing Check Valve is offered by us. It is made up of combination of tensile iron and steel to give high physical strength and high corrosion resistance. It is spring loaded and lined with PTFE to give longer cycle life. PTFE Lined Swing Check Valve is majorly used for fluids compatible with the corrosion resistance characteristics of the valve.

Engineered for Corrosive Applications

Our PTFE Lined Swing Check Valve provides optimal corrosion protection for aggressive chemical processes. Its PTFE lining shields the valves internal surfaces from acids, alkalis, and solvents, maintaining a leak-proof seal even in the harshest environments. Ideal for various industries, including pharmaceuticals and water treatment plants, this valve ensures safe and efficient fluid handling.

Robust Construction and Versatile Standards

Built with a cast or ductile iron body and a seamless PTFE lining, this valve complies with international standards such as ASTM, ASME, DIN, and ISO. Flanged end connections adhere to ANSI B16.5 or DIN PN10/PN16 specifications, with face-to-face lengths matching ASME B16.10 or specific requirements, guaranteeing compatibility and reliability in any industrial setup.

Simple Installation and Maintenance-Free Operation

Installation is straightforwardmount horizontally, and the valve functions automatically as flow actuates the swing-action disc. No external power or actuation is required, resulting in maintenance-free operation and a reduced risk of operational failure. Optional accessories such as limit switches or drain ports are available for customized performance.

FAQs of Ptfe Lined Swing Check Valve:

Q: How does the PTFE Lined Swing Check Valve operate?

A: This valve operates automatically using the pressure of the line fluid. When fluid flows in the correct direction, the PTFE lined disc swings open, allowing passage. Should the flow reverse, the disc closes, preventing backflowno external actuation or power is required.

Q: What types of end connections and standards are available for this valve?

A: The PTFE lined swing check valve is offered with flanged end connections conforming to ANSI B16.5 and DIN PN10/PN16 standards. Face-to-face dimensions follow ASME B16.10 or customer specifications, ensuring seamless integration into various piping systems.

Q: When should I use a PTFE lined swing check valve in my process?

A: This valve is ideal for applications where the handled fluid is highly corrosive, such as in chemical, pharmaceutical, petrochemical, or water treatment operations, and where zero-leakage and minimal maintenance are critical.

Q: Where can the PTFE lined swing check valve be installed?

A: The valve is designed specifically for horizontal installations in pipelines that convey corrosive liquids, gases, or solvents. Its compact flanged design allows for easy fitment in industrial process lines within manufacturing plants, treatment facilities, or laboratories.

Q: What makes PTFE lining beneficial in swing check valves?

A: PTFE lining provides exceptional chemical resistance, ensuring bubble-tight sealing (Class VI) and preventing internal corrosion. This results in an extended operational lifespan, low maintenance, and reliable zero-leakage performance even under aggressive service conditions.

Q: How is the valve tested for quality and performance?

A: Each valve undergoes rigorous testingbody test pressure at 1.5 times the rated pressure and seat test pressure at 1.1 timesto confirm structural integrity and leak-proof sealing in compliance with international quality standards.
