The AA144P-3 Electric Solenoid Valve has a polypropylene body for chemical resistance. However, you should review the manual before using a new chemical with this product. Like other solenoid valves, this product is controlled by an electric current. The electrical connections of the valve are protected with a cap to help reduce potential damage and corrosion. The mounting slot, which is integrated in the valve, can have a 6mm bolt or a 10 mm hex head.
