UNIDIRECTIONAL VALVES HIGH TEMPERATURE
Unidirectional valves are made of acetal resin and have retaining gaskets and stainless-steel springs, which guarantee a resistance of up to 120°C. It is also possible to replace certain components in accordance with the client’s needs (e.g.: Viton or silicon retaining gaskets, springs with different loads).
Unidirectional valves, also called anti-suction or check valves, are used to control the flow in order to guarantee the non-return of contaminated water.
