1 Sizes through 1 Pressure settings 1 oz/in to 15 PSIG Available in aluminum (type 56), carbon steel, stainless steel and other materials. PRESSURE RELIEF VALVE MODEL 00A EMERGENCY RELIEF VALVE Model 00A is designed for emergency relief capacity above that supplied by a standard operating valve used on tanks, piping, and low pressure vessels. Emergency relief valves provide relief from excessive internal pressures which may cause tank damage. SPECIAL FEATURES Model 00A is built of corrosion resistant material throughout. Groth s self-closing special teflon cushioned air pallet with center stabilizing stem and peripheral guiding provides uniform seating and alignment. Superior performing Teflon seating diaphragms are standard to minimize sticking caused by resinous vapors and atmospheric moisture. The guides support a spun weatherhood which covers and protects the entire valve structure. As added protection against the entry of foreign matter, a mesh screen encircles the valve under the weatherhood. GROTH, THE CAPABILITY COMPANY MODEL 00A MODEL 00A As with all Groth products, every Model 00A is factory inspected and tested to meet your critical requirements and special needs. Inventory is maintained to insure rapid delivery. MODEL 01A 10
