Pressure Vacuum Relief Valve
The Pressure Vacuum Relief Valve is designed with the guidelines of ISO 15364 in mind and represents the highest level of safety and maintenance-free operation available. It eliminates pressure surge and VOC loss. It has multi-adjustable features for opening and closing pressure with an optimum characteristic in regards to pipe diameter savings and minimization of vapor loss. The working pressure can be increased by 25-50% without reducing safety margins.
