About Single Plate Non Return Valves

We are engaged in manufacturing and supplying a quality range of Single Plate Non Return Valves. These valves are precision engineered using the advanced technology and are used for throtting and controlling the pressure of various liquids. Further, these valves can be purchased at industry leading prices

Versatility in Industrial Applications

These single plate non return valves are suitable for various media, such as water, oil, gas, air, and even corrosive fluids, making them an excellent choice for industries ranging from chemical processing to HVAC and water supply. Their compatibility with manual and automatic control ensures seamless fluid management across different systems.

Reliable Performance and Durable Design

With a stainless steel spring and pin, epoxy powder-coated body (in cast/ductile iron models), and zero-leakage sealing, the valves are built to deliver consistent operation and extended service life. Low pressure drop and quick closing action ensure both safety and efficiency.

Flexible Installation and Broad Compatibility

Designed to mount easily between flanges of diverse standards (DIN, ANSI, BS), these valves are offered in a wide port size range (DN40DN600) and are installable in horizontal or vertical (upward flow) pipe setups, enabling use in both new projects and retrofits.

FAQs of Single Plate Non Return Valves:

Q: How are single plate non return valves installed in pipeline systems?

A: These valves are designed to be installed directly between flanges conforming to DIN, ANSI, or BS standards. They can be mounted in horizontal pipelines or vertically if the flow direction is upward, making installation straightforward and adaptable.

Q: What media can these valves handle effectively?

A: Single plate non return valves are suitable for a broad range of media, including water, oil, air, gas, and various corrosive fluids. Their construction and sealing options (EPDM, NBR, Viton) allow compatibility with industrial, chemical, and HVAC systems.

Q: When should I choose a non return valve with a single plate wafer design?

A: This design is ideal when you need a compact, lightweight valve with low pressure drop and quick response, especially in systems where space is limited and backflow prevention is critical, such as water supply, chemical pipelines, and HVAC applications.

Q: Where are these valves typically used in industry?

A: Common applications include industrial fluid control systems, water distribution networks, chemical and petroleum pipelines, as well as heating, ventilation, and air conditioning (HVAC) setups. Their versatility allows for use across single or multiple industries.

Q: What is the benefit of zero leakage (bubble tight) performance?

A: Zero leakage ensures that the valve prevents any reverse flow, protecting pumps, pipelines, and equipment from damage and ensuring system integrity, which is crucial in sensitive fluid handling applications.

Q: How does the valve achieve low pressure drop and quick closure?

A: The single plate design and stainless steel spring allow for rapid closing action as soon as flow stops or reverses, while the streamlined internal structure reduces flow resistance, minimizing pressure drop across the valve.

Q: What process should be followed for selecting port size and materials?

A: Selection depends on pipeline dimensions (DN40 to DN600), system pressure requirements (PN10/16/25), type of fluid handled, and environmental conditions. Material options for the body and disc (cast/ductile iron or stainless steel) and seal (EPDM, NBR, Viton) should align with the application to ensure optimal valve performance and longevity.
