Asten Controls LLP

Product Description:

We offer a premium-quality Lift Type Check Valve designed for unidirectional flow control in high-pressure and high-temperature pipelines. This non-return valve operates automatically, using line pressure to open and close the valve disc, effectively preventing backflow and protecting pumps, compressors, and piping systems.

Constructed from robust materials such as Cast Iron, Cast Steel, Stainless Steel (SS304, SS316), Forged Steel, and Bronze, our lift check valves are ideal for industrial applications involving steam, gas, oil, water, and corrosive fluids. With precise machining and leak-proof sealing, these valves ensure maintenance-free performance and extended service life.

Non Return Valve (NRV) – One-Way Flow Valve for Industrial and Domestic Use

Our Non-Return Valve (NRV) is designed to allow fluid flow in one direction only and prevent backflow in pipelines, ensuring the protection of pumps, compressors, and other critical equipment. This valve automatically closes if the flow reverses, making it essential for liquid and gas systems in both industrial and domestic applications.

Available in a variety of materials and configurations such as Swing Type, Lift Type, Wafer Type, and Spring-Loaded, our NRVs are suitable for water, steam, air, oil, and chemical lines. Built to industry standards, they offer leak-proof operation, corrosion resistance, and long service life.
