Our HVJ pressure balanced valve uses the pressure of the product to help close the valve and prevent valve hammer on closing. It is operated by a single air signal. Our HVG single acting valve is designed to close when a signal pressure is applied to the top of the piston. The pressure of flow that the valve can control is proportional to this signal pressure. It is operated by a single air signal, and normally remains open.
