Outstanding Corrosion Resistance

The MS PTFE Non Return Lined Valve utilizes full PTFE lining and a corrosion-resistant epoxy powder-coated body. This combination provides exceptional durability in harsh chemical and industrial environments, minimizing downtime and extending the valves overall service life.

Leak-Proof Performance for Critical Applications

Equipped with a PTFE resilient seat and designed to meet Class VI (bubble tight) leakage standards, this valve ensures a secure seal against aggressive liquids and gases. Its unidirectional, swing type mechanism guarantees reliable, maintenance-free operation even under challenging conditions.

Versatile Installation and Customization Options

The valve supports installation in horizontal pipelines and is available with flanged ends compatible with ANSI, DIN, JIS, and BS standards. Customizable port sizes (25mm to 300mm) and inspection port availability allow seamless integration into a variety of industrial systems.

FAQs of MS PTFE Non Return Lined Valve:

Q: How is the MS PTFE Non Return Lined Valve installed in a pipeline system?

A: This valve is designed for horizontal installation and features flanged ends compatible with ANSI, DIN, JIS, and BS standards. It is easily mounted between flanges, secured using suitable fasteners, and can be installed right out of the box with standard export packing.

Q: What makes the valve suitable for handling corrosive chemicals and aggressive media?

A: The valves mild steel body is completely lined with PTFE, offering excellent chemical resistance. The PTFE resilient seat and lined disc prevent corrosion and leakage, ensuring reliable performance with corrosive liquids, gases, and chemicals.

Q: When is it appropriate to use this non return valve in an industrial setting?

A: This valve is ideal for use in chemical plants, water treatment facilities, pharmaceutical processes, and petrochemical industries where backflow prevention in corrosive environments is critical. Its robust design supports continuous operation and long service life.

Q: Where is the inspection port located and how can it be requested?

A: An inspection port can be provided on the valve upon request during order placement. Its location and integration are handled as per customer specifications and manufacturer standards, enabling easy maintenance or inspection when needed.

Q: What are the benefits of the PTFE lining and epoxy coating used in the valve?

A: PTFE lining offers exceptional chemical resistance and leak prevention, while the epoxy powder coating shields the exterior against corrosion. This dual protection ensures durability, low maintenance, and longevity even in harsh operational conditions.

Q: How does the valve ensure minimal pressure loss and efficient flow control?

A: The valve is designed with a low opening pressure, allowing fluid to pass with minimal resistance. Its swing-type construction and bubble-tight seal prevent backflow and leakage, maintaining efficient, unidirectional flow with minimal energy loss.
