Ultimate User Control with the Model #330
Allowing users ultimate control, Model #330 Manual Relief Valve manages pressure relief at the touch of a button. The push button feature comes into direct contact with the poppet, which allows no flow to pass through it until it is manually pressed. This style is different from our other check and pressure relief valves, which react to a set opening pressure. Pictured in red Polypropylene (and paired with Model #302), the Model #330 is designed to vent pressure or be used as a vacuum. It works with liquid or air applications, but we recommend air in most cases because of hand to button contact. For easy installation in control panels or any flat surface, Model #330 is a 5/8 - 18 UNF (Unified National Fine) thread, and it can also be combined with any Series 300 end fitting.
