186567 Refrigerating Specialties (RS) 3/4 x 1 SRV H3, 130 psi

Safety Relief Valves should be used to protect each refrigeration system pressure vessel that can be isolated by valves. In many localities state or municipal codes govern selection and installation of Relief Valves. Many are patterned after the ASME Boiler and Pressure Vessel Code and the ANSI/ASHRAE 15-78 Safety Code for Mechanical Refrigeration. Where no compulsory code exists, installation of Relief Valves according to this ANSI/ASHRAE Code is highly recommended. The Type H High Capacity Safety Relief Valves are designed and constructed to meet the requirements of ASME Boiler and Pressure Vessel Code and ANSI/ASHRAE 15-78 Code requirements and bear the ASME Code Symbol (UV) indicating compliance with these codes. Employing proven principles of design, these Safety Relief Valves are highly reliable and dependable. Precision machined moving parts of stainless steel, a PTFE disc and a cadmium plated spring prevent sticking due to corrosion or cold welding, to assure valve opening at the set pressure long after installation. They are not suitable for corrosive ambient atmospheres such as chlorine, etc. The two-bolt flanged bottom inlet affords simple removal and replacement.Features:High CapacityExcellent RepeatabilityAll Stainless Steel Internal PartsMaximum Temperature 300°FUnaffected By VibrationDrain Plug StandardPTFE Seat
