The 2-way valve’s body was molded from brass with two 1-1/4” Female NPT Ports, and a 32mm orifice. This valve is uni-directional as noted by the arrow on the valve body and will not operate properly in the opposite direction or if there is back-pressure on the diaphragm. Once energized this valve will snap shut in under one second as the coil creates a magnetic field that pushes the diaphragm down against a spring! This valve will remain closed until the power is switched off and the spring pushes the diaphragm back up allowing media to pass through the valve once again. This valve series are Normally Open, or in the Open position when not energized. ![]() The position of the valve refers to the non-energized position. Semi-direct acting valves are the crossroad between direct acting and piloted solenoid valves allowing them to work from zero bar and manage a high flow rate meaning this valve is great for use when either gravity feed or a high flow is required. Classified as a two-way, semi-direct lift valve, sometimes referred to as assisted lift, this normally open valve has a broad array of uses. ![]() The BZW-32K series of Normally Open Valves is manufactured solid with the body cast out of brass, stainless steel wetted components and a Viton seal.
