    Compact Pressure-Relief Valves

    Due to their small size, these valves are often installed on tanks in low-clearance areas. They begin opening at the set pressure. Nylon valves fully open at about 10% over the set pressure and steel valves fully open at about 50% over the set pressure. Valves begin closing as pressure drops and fully close when the system pressure is restored below the set pressure. All have a vent outlet to exhaust discharge directly. Set pressure is not adjustable.
