Vertical Check Valve, ASTM A351 CF8, 1000 WOG, NPT

Key Specifications / Features

The China Vertical Check Valve Manufacturer produces robust vertical check valves with a cast stainless steel body made from ASTM A351 CF8 material. These valves have a size of 1-1/2 inch (DN40) and are rated for a pressure of 1000 WOG (Water, Oil, and Gas). They feature NPT (National Pipe Thread) threaded ends for secure and easy connections. Designed to prevent backflow in vertical piping systems, these valves are ideal for applications involving water, oil, and gas, ensuring reliable performance and durability.

Check valves are designed to allow flow in one direction only. With stainless steel bodies and PTFE seals, these valves offer excellent corrosion resistance, making them suitable for a wide range of fluids, including water, oil, gas, air, light alkalis, acids, biodiesel, fuels, and alcohols. Vertical check valves can be used in various applications. They feature a spring mechanism that closes the disc when the fluid pressure is insufficient to keep it open. If fluid tries to flow backward, the valve closes automatically to prevent backflow.
