About Non-Slam Disc Check Valve Manufacturer in India

FlowBiz Brand non-slam check valve refers to the automatic opening and closing valve disc that depends on the flow of the medium itself, which is operated to lower the noise when open or closed, also known as the nozzle check valve.

Our non-slam check valve belongs to an automatic valve. Its main functions are to prevent the backflow of the medium, prevent the pump and drive motor from reversing, and release the medium of the container. Our non-slam check valve can also supply lines that replenish the auxiliary system where the pressure may rise above the system pressure.

FlowBiz Non-slam check valves are also used in similar applications throughout the chemical processing industry, steam condensate systems, and the power generation industry.

Features and Advantages of Non-Slam Disc Check Valves:

Reverse Flow Prevention
Water Hammer Mitigation
Minimal Pressure Drop
Durability and Reliability

Engineered for Precision and Reliability

Our non-slam disc check valves are designed to meet stringent international standards, including API 594, BS EN 12334, and IS 5312. Featuring wafer type and flanged end connections, they provide versatility for diverse industrial applications. The valves are maintenance-free, self-actuated, and suitable for both horizontal and vertical installations, ensuring adaptability and dependable performance in dynamic pipeline systems.

Enhanced Corrosion Protection and Tight Sealing

With an epoxy-coated exterior and stainless-steel or alloy-steel components, these valves excel in lasting corrosion resistance. The sealing options-EPDM, Nitrile, Viton, or PTFE-ensure leak-free operation, meeting Class VI leakage requirements. Gasket or O-ring seals on body cover joints enhance pressure retention, supporting safe operation at high pressures and temperatures from -20C to 200C.

Exceptional Versatility for Industrial Applications

Suitable for media such as water, oil, gas, and air, and operating across a wide pressure spectrum (PN10 to Class 300), our check valves are trusted for use in water treatment plants, chemical processing, power generation, and the oil & gas industry. Their low pressure drop, non-slam closing, and corrosion resistance make them an ideal choice for modern pipeline systems.

FAQ's of Non-Slam Disc Check Valve Manufacturer in India:

Q: How does a non-slam disc check valve operate in pipeline systems?

A: A non-slam disc check valve enables unidirectional flow, automatically preventing reverse flow without the need for external power. Its disc closes rapidly and gently when flow stops or reverses, minimizing pressure surges ('water hammer') and ensuring system protection.

Q: What end connection standards and valve sizes are supported by your product?

A: Our non-slam disc check valves comply with ANSI, DIN, JIS, and BS end connection standards. We offer a broad range of sizes from DN50 to DN600 (2" to 24"), ensuring compatibility with various international pipeline requirements.

Q: When should I choose a non-slam check valve over other types?

A: Non-slam check valves are ideal when it is critical to prevent water hammer and pressure shock-common in systems with rapidly fluctuating flows. Their quick-closing, maintenance-free design makes them suitable for sensitive or high-performance applications across different industries.

Q: Where can non-slam disc check valves be installed?

A: These check valves are designed for both horizontal and vertical (upward flow) installations. Their compact wafer or flanged ends allow for easy integration into existing or new pipelines in water treatment, power plants, chemical, and oil & gas facilities.

Q: What process is followed for valve testing and quality assurance?

A: Each valve undergoes rigorous testing in line with international standards: the body is tested at 1.5 times the design pressure and the seat at 1.1 times the design pressure. This ensures mechanical integrity and leak-free sealing under actual service conditions.

Q: How does your valve's design benefit system operation and longevity?

A: The non-slam mechanism prevents destructive pressure surges, reducing wear on piping and pumps. Corrosion-resistant coatings and alloys, tight Class VI sealing, and a maintenance-free structure all contribute to extended service life and operational reliability.
