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.
