About Swing Check Valve

With utmost support from our talented employees, we are one of the leading companies engaged in business of manufacturing and supplying Swing Check Valve. It is mounted on a disc that swings on a hinge or shaft. Our valve is extensively used in industry to allow forward flow and disallow backward flow of fluid. This valve automatically shuts off on gravity due to weight of disc. Swing Check Valve requires a minimum force to operate and has a lip sealing on disc to ensure tightness.

Features:

Very less maintenance required
Low-pressure drop across valve
Very low turbulence

The table provides details of the materials as per the specific conditions of the service, some materials appropriate for the handling of uncommon fluids are not included, but can be supplied upon customer's request.

Carbon steel for general use.
Stainless steel for corrosive.
Alloy stell for low temp./high temp service.
Alloy 20, Hastelloy, monel for highly corrosive or abrasive application.

Reliable Non-return Operation

Equipped with a single swing disc, this valve ensures flow occurs in only one direction, eliminating the risk of reverse flow in pipelines. The self-acting, maintenance-friendly design provides consistent performance for industrial, water, oil, and gas applications, with pressure classes up to 600 class rating.

Engineered for Durability and Versatility

With materials like cast iron, stainless steel, and ductile iron, plus varied sealing optionsincluding PTFE, rubber, and metalthe valve suits wide temperature ranges (-10C to 200C) and diverse media. An anti-corrosive epoxy finish and optional stainless steel pin further increase service life and reliability in harsh conditions.

FAQs of Swing Check Valve:

Q: How should the Swing Check Valve be installed for optimal performance?

A: It is recommended to install the Swing Check Valve in a horizontal position for best performance, as indicated by the flow direction marking on the body. Vertical installation is also possible if designed accordingly. Always ensure the valve is oriented so flow follows the marked direction to prevent backflow.

Q: What standards and testing protocols are followed for this check valve?

A: The end connections comply with ANSI B16.5 or BS 10 Table D/E/F, with face-to-face dimensions according to ASME B16.10 or equivalent. Each valve undergoes a body test pressure at 1.5 times and seat test at 1.1 times the working pressure, ensuring robust, reliable operation under demanding conditions.

Q: When should I choose metal versus soft seat sealing in this valve?

A: Metal-to-metal sealing is suitable for high temperature, abrasive, or steam applications, while soft-seated options (PTFE or rubber) are ideal for achieving bubble-tight shutoff in water, oil, or chemical service. The selection depends on the media and temperature requirements of your system.

Q: Where can this Swing Check Valve be utilized?

A: This check valve is versatile, suitable for water, oil, steam, gas pipelines, process industries, and chemical services. Common installations include utility pipelines, industrial process systems, and applications involving up to 20 bar pressure and temperatures from -10C to 200C, depending on material selection.

Q: What are the benefits of the anti-corrosive epoxy coating?

A: The anti-corrosive epoxy paint or customer-specified coating ensures enhanced protection against rust and degradation, significantly increasing the valves lifespan when used in harsh, humid, or chemical-laden environments.

Q: How does the swing check valve operate and what is its main function?

A: The valve operates automatically, allowing flow in only one direction through a single swing disc. It prevents reverse flow (non-return function) without the need for manual intervention or external power, safeguarding pumps, meters, and equipment downstream.
