186380 Refrigerating Specialties (RS) 1/2 x 3/4 SRV SR1, 235 psi

The Type SRH High Capacity Safety Relief Valves are designed and constructed to meet the requirements of Section VIII ASME Boiler and Pressure Vessel Code and ANSI/ASHRAE 15 Code requirements and bear the ASME Code Symbol (UV). Employing proven principles of design, these Safety Relief Valves are highly reliable and dependable. Precision machined moving parts of stainless steel, and a PTFE disc prevent sticking due to corrosion or cold welding and assure valve opening at the set pressure long after installation. They are not suitable for corrosive ambient atmospheres such as chlorine, etcSafety 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 Safety Code for Mechanical Refrigeration. Where no compulsory code exist, installation of Relief Valves according to this ANSI/ASHRAE Code is highly recommended.Features:ANSI / ASHRAE 15 ComplaintExcellent Repeatability / Unaffected by VibrationAll Stainless Steel Internal PartsPTFE SeatCapacity Rating for Vapor OnlyPressure Settings 150 to 400 psi
