Dual Plate Check Valves The dual plate check valve is one of the most compact check valves. When fluid enters the valve, the pressure causes the doors to open, stretching the spring. When the flow stops, the spring returns to its compressed state, making the plates return to the closed position, ensuring a quick closing. TALIS Dual Plate check valves offer a wide range of possibilities according to your applications and network operating conditions. Maximum working temperatures depend on materials selection.
