The check valve d110 is intended for large pool and industrial installations where the circulation pipework reaches a diameter of 110 mm. The PVC-U body ensures maximum resistance to corrosion from the chemicals contained in pool water.
The AISI 302 stainless steel spring and EPDM seal guarantee reliable closing of the flap after every stop of the pump, thereby protecting the entire hydraulic circuit against back flow. The valve meets the operating conditions of 16 bar at 20 °C and 10 bar at 40 °C. Suitable for fibreglass, concrete and stainless steel pools with extensive pipework.
