Hammer Non Return Valves and Check Valves
C.P. Valves Industry, we specialize in providing high-quality Hammer Non return valves and Check valves are designed to allow fluid flow in one direction while preventing backflow, ensuring system efficiency and protecting pumps, pipelines, and equipment. Whether used in water supply systems, sewage treatment, industrial processing, or oil and gas applications, our NRVs provide reliable performance, leak-proof sealing, and long-lasting durability.
Types Of Non Return Valves
Hammer Non return valves and Check valves are available in a wide range of configurations to meet different system needs:
- Ball Type NRV – Uses a ball to block backflow, ideal for water and industrial applications.
- Lift Type NRV – Features a guided disc that lifts when fluid flows forward and seals when it stops.
- Dual Plate NRV – Equipped with two spring-loaded plates for quick shutoff and minimal pressure loss.
- Horizontal & Vertical Type NRV – Designed for both horizontal and vertical piping systems.
- Reflux Type NRV – Prevents backflow in large water distribution systems.
- Swing & Wafer Type NRV – Hinged disc swings open for flow and seals tightly when closed.
- Disc & Multi Type NRV – Versatile designs for specialized applications.
Materials & Construction Of Hammer Non Return Valves
Hammer Non return Valves and Check Valves are manufactured using premium materials to suit different environments:
- Cast Iron (CI) & Carbon Steel (CS) – Strong and durable for general industrial use.
- Stainless Steel (SS-304 & SS-316) – High corrosion resistance, ideal for chemical, pharmaceutical, and food industries.
- Gunmetal (GM) & Brass – Used in marine, water, and plumbing systems due to excellent corrosion resistance.

Comprehensive Non Return Valves and Check Valves Performance and Specifications
Hammer Non-Return Valves and check valves engineered to provide superior flow control, minimal pressure drop, and long service life. Available in sizes from 15mm (1/2″) to 1000mm (40″), these valves efficiently prevent backflow in water, oil, gas, chemical, and industrial piping systems. Designed with high-quality materials like stainless steel, brass, carbon steel, and polypropylene, our NRVs offer resistance to corrosion, high pressure, and extreme temperatures.
The ball type non return valves, swing check non return valves, and dual plate non return valves ensure leak-proof sealing, while the lift and disc-type non return valves provide smooth and reliable operation under varying flow conditions. Whether you’re looking for a PVC non-return valve for sewage pipes, a brass non return valves for water pumps, or a wafer-type NRV for compact installations, Hammer NRVs are built for efficiency, durability, and trouble-free performance.
