About Ball Type Non-Return Valves

Ball Type Non-Return Valves

The offered Ball Type Non-Return Valves is commonly used in heavy duty hydraulic systems to ensure the unidirectional flow of the liquid which is controlled with the help of a metal ball placed inside the casing of this heavy duty component part. It acts as a safe guard for the installations such as pumps, compressor and many more to prevent damages due to the back flow. It is made up by using plastic materials with high strength to weight ratio.

Superior Corrosion Resistance for Reliability

Protected by a durable epoxy powder or painted coating, these ball type non-return valves are engineered to withstand harsh, corrosive environments common in industrial, chemical, and sewage applications. The meticulous coating process extends valve lifespan by defending against rust and chemical attack, thereby ensuring consistent, long-term performance even with aggressive or slurry-laden media.

Effortless, Maintenance-Free Operation

Designed with a solid, rubber-coated or stainless steel ball and soft nitrile/EPDM seat, the valve operates smoothly under low pressure with gravity flow. Thanks to the self-acting mechanism, no external power or lubrication is required. Their robust build and minimal moving parts mean reduced maintenance needs, contributing to lower operational costs across diverse installations.

FAQs of Ball Type Non-Return Valves:

Q: How does the ball type non-return valve ensure leak-proof performance?

A: The valve employs a solid stainless steel or rubber-coated ball that seats against a soft nitrile or EPDM material. This design provides a tight, leak-proof seal with minimal pressure, effectively preventing backflow in all approved applications.

Q: What are the installation options for these non-return valves?

A: These valves are versatile and can be installed in horizontal or vertical upward orientations. They are compatible with flanged or screwed end connections conforming to ANSI, DIN, BS, and IS standards, making them suitable for various piping systems globally.

Q: When is it beneficial to use a ball type non-return valve with an epoxy powder coated body?

A: An epoxy powder coated body is particularly recommended in environments where corrosion resistance is paramount, such as in wastewater treatment, chemical processing, and other industrial applications exposed to aggressive or moist media.

Q: What kind of maintenance does this valve require?

A: Ball type non-return valves are designed for minimal maintenance. They do not require regular lubrication due to their simple, robust mechanism, and their self-acting nature greatly reduces the need for ongoing service, lowering both downtime and operating costs.

Q: Where can these valves be used effectively?

A: These valves are ideal for industrial water supply, sewage and wastewater plants, chemical processing units, effluent treatment facilities, and pumping stations, where gravity flow or low opening pressure is required.

Q: How does the valve perform under different temperature and pressure conditions?

A: The valve is suitable for working temperatures ranging from -10C to +80C and pressure ratings of PN 1.0 and PN 1.6 (10-16 bar). It is hydrostatically tested at 1.5 times its maximum working pressure for safety and reliability in demanding applications.

Q: What are the benefits of the ball type design in these non-return valves?

A: The ball type design offers a low pressure drop, rapid closing to prevent reverse flow, high resistance to jamming, and reliable sealing. Its single-piece body and soft seating ensure minimal maintenance and dependable long-term functionality.
