Stainless Steel SS316 Spring Check Valve 1/4” to 2” Heavy Duty One Way Non Return Backflow Prevention Valve

Welcome to AF Hydro! We offer a wide range of valves & fittings for your everyday needs. Product description: The purpose of the spring check valve is to prevent backflow by ensuring that fluid moves in only one direction. It is also known as a non-return valve and one-way valve. The spring check valve works when there is a difference in pressure. When the pressure of the fluids on the inlet side is higher than the cracking pressure, fluid flows. Cracking pressure is the minimum upstream inlet pressure to open the check valve and allow fluid to pass through. Applications: Suitable for general water, oil, and gas applications. What is the difference between metal and soft seats?Metal seat: Best used in conditions that are corrosive and have high pressure and temperature up to 537°C.Soft seat: Made of thermoplastic material. Best used for applications that need chemical compatibility for sealing. Benefits: Protection against reverse flow damage.Easy installation.Steel grade provides a higher resistance against corrosion and rust.Flexibility in installation as it can be installed vertically or horizontally.
