About Single Disc Check Valves

FlowBiz Exports Pvt Ltd Valves is a High Quality Single Disc Check Valve Manufacturer in Mumbai, Maharashtra, India. We are a leading manufacturer of Single Disc Check Valve in Mumbai and nearby areas.

The Single Disc Check Valve (Wafer Type Single Disc Check Valve) consists of four main components, the body, a disc, a star guide and a spring. The Disc check valves are opened by the pressure of fluid and closed through compression spring as soon as flow stops thus preventing reverse flow.

Specifications :

The flap type single Disc Check Valves are designed as per the API 6D/API 594 manufacturing standard. The pressure rating of the valve ranges from 150# to 300# with spring loaded Single disc, hinged on the body.

Design and Versatility

Single Disc Check Valves come in a wafer type structure, allowing for compact installation between standard flanges (EN 1092-1, ANSI B16.5). This design supports both horizontal and vertical (upward flow) positions, providing installation flexibility in various piping configurations. The quick-closing swing disc mechanism ensures reliable non-return function for both liquids and gases.

Material and Quality Assurance

Manufactured to conform with DIN, BS, and EN standards, these check valves offer a range of robust body and disc materials, including stainless steel, ductile iron, and bronze. The epoxy powder coating on cast iron models enhances corrosion resistance, while stainless steel springs and precision seats (soft or metal) ensure long-term durability and leak-tight performance as per EN 12266-1.

Performance and Applications

Designed for pressures up to PN25 and temperatures reaching 180C (depending on seat material), these valves serve a wide array of industrial sectors. They are ideal for water, oil, gas, and steam lines, delivering benefits like low pressure drops, rapid response, minimal maintenance, and seamless self-acting operation without the need for external control systems.

FAQs of Single Disc Check Valves:

Q: How are Single Disc Check Valves installed in a pipeline system?

A: Single Disc Check Valves are installed using a wafer fitment, meaning they are placed between two flangescompatible with EN 1092-1 or ANSI B16.5 standards. They can be installed in either horizontal or vertical (upward flow) pipe orientations, offering versatility for various pipeline layouts.

Q: What media and applications are suitable for these check valves?

A: These valves are designed for a wide assortment of media, including water, oil, gas, and steam. Their robust construction and range of available materials make them suitable for industrial pipelines, utility networks, and power generation systems.

Q: When should I consider using a check valve with a specific disc material like CF8M or DI?

A: The choice of disc material depends on your applications requirements and the chemical compatibility with the process fluid. For corrosive or high-temperature environments, stainless steel options like CF8 or CF8M are ideal, while ductile iron (DI) offers cost-effective durability in less aggressive conditions.

Q: Where do these check valves conform to international standards?

A: These valves adhere to several major international standards, including EN 558 Series 16 (face to face), EN 1092-1 and ANSI B16.5 (end connections), EN 12266-1 (leakage), and additional DIN and BS standards, ensuring global suitability and product reliability.

Q: What is the testing process for confirming valve performance?

A: Each valve undergoes hydrostatic testing as per specification, with the body tested at 1.5 times PN (nominal pressure) and seat at 1.1 times PN. This rigorous process ensures leak-tight integrity and reliable operation under maximum pressure conditions.

Q: How does the valve ensure rapid and reliable closure?

A: The single, centrally-pinned swing disc, combined with a stainless steel spring (where applicable), promotes a quick closing response to reverse flow. This mechanism prevents backflow and minimizes water hammer risks, enhancing system safety.

Q: What are the benefits of choosing a wafer type, single disc check valve?

A: Key advantages include compact design, straightforward installation between flanges, low pressure drop across the valve, reduced maintenance, and fast, reliable response to flow direction changes. These features together make it an efficient, cost-effective solution for non-return applications.
