Pressure relief valve
Wandfluh has extended the proven pressure relief valve with a K9 execution for use in highly corrosive environments. The valve is made of stainless materials and is coated with a high-quality surface protection. It can switch volume flows up to 25 l/min at up to 315 bar. The valve is used for limiting the operating pressure in hydraulic systems or to protect against overloads caused by pressure peaks and can be adapted to the respective application requirements with pressure stages of 63, 210 and 315 bar. The desired pressure can be set with a tool or a selection of buttons. The setting can be protected against unauthorized access with the "cover" option. The direct operated valve is available with the designation BA_PM22_K9. It is mainly used in areas with continually changing weather conditions or in the vicinity of the sea.
