A check valve, also called a non-return valve (NRV), is a safety device that ensures fluid flows in only one direction and automatically prevents backflow. These valves are critical for protecting pumps, compressors, and motors from reverse flow damage.And best Check Valve Price List
for udhhyog In India, check valves are used in:
- Water supply & irrigation pipelines
- Air compressors and pneumatic systems
- Boilers and feedwater systems
- Hydraulic presses & industrial machinery
- Oil and gas pipelines
- LPG, CNG, and chemical systems
With infrastructure growth in 2025, the demand for water pump check valves, hydraulic check valves, and pneumatic NRVs has risen across sectors. Buyers often compare check valve prices by size (1 inch, 2 inch, 3 inch, 4 inch) and look for reliable brands like Zoloto, Audco, Kartar, Sant, and Kirloskar.
Working Principle of a Check Valve
A check valve is self-operating. It opens when forward flow pressure exceeds the closing element (disc, ball, spring) and shuts when reverse flow begins.
Operation:
- Forward flow → Valve opens automatically.
- Reverse flow → Disc or ball closes, preventing backflow.
Advantages:
- Protects equipment from damage
- Prevents water hammer in pipelines
- Maintains system efficiency
- Works automatically without manual input
