About Swing Flex Check Valves

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

The Swing-Flex Check Valve is the valve of choice based on its simple maintenance-free design, low headloss and non-slam characteristics. The valve's smooth, unrestricted full flow design makes it an excellent choice for slurries and sludge, even in vertical flow up applications.

Application:

Swing check valves have many uses, from sewage systems and wastewater treatment to firefighting, power plants, and various household items. One of the most commonly known examples of this valve type is the swing check valve that allows water to enter a toilet's tank while blocking the reverse flow.

Features:

- Excellent seating

- Precision machined

- Fine finish

Reliable Performance and Versatile Applications

Swing Flex Check Valves are designed for high reliability, featuring corrosion-resistant materials, robust construction, and flexible operation. These valves offer zero leakage and seamless usability in potable water, sewage management, industrial, and firefighting systems. The non-slam, self-closing design assures consistent protection against backflow, making them ideal for demanding environments.

Easy Installation and Maintenance

With a flow direction arrow cast on the body, Swing Flex Check Valves simplify installation. The bolted top cover enables easy access for inspections and maintenance, reducing downtime. Flanged ends compatible with ANSI, DIN, and BS standards meet diverse piping requirements, while the lightweight construction across various sizes ensures manageable handling.

FAQ's of Swing Flex Check Valves:

Q: How do the Swing Flex Check Valves prevent backflow and ensure zero leakage?

A: The Swing Flex Check Valves use a flex-body, single disc design with EPDM or NBR sealing for a tight shut-off. Under specified pressure, the valves guarantee zero leakage, protecting piping systems from backflow and fluid loss.

Q: What installation options and standards do these valves support?

A: These valves feature flanged ends compatible with EN 1092-2, ANSI B16.1, and BS 4504 standards, accommodating various pipeline specifications. The cast flow direction arrow makes correct installation clear and simple.

Q: When is maintenance required for Swing Flex Check Valves, and how is it performed?

A: Routine maintenance is minimal due to their maintenance-free design. If inspection or servicing is necessary, the bolted top cover offers convenient access to internal components without removing the valve from the pipeline.

Q: Where can Swing Flex Check Valves be applied?

A: These valves are suitable for potable water supply, sewage handling, wastewater treatment, fire protection systems, and diverse industrial applications, offering flexible usage across multiple sectors.

Q: What benefits does the fusion bonded epoxy coating provide?

A: The fusion bonded epoxy (FBE) coating, applied at a minimum thickness of 250 microns, delivers excellent protection against corrosion and harsh environments, extending the valve's operational lifespan.

Q: How does the valve's design minimize pressure drop and noise?

A: The flex-body, non-slam swing type mechanism reduces pressure drop across the valve and eliminates water hammer, resulting in quieter operation and enhanced system safety.
