SV44H Carbon Steel Safety Valve
Description SV44H Safety Valves are high-capacity valves with standard orifices from F to R. They have a modern design with two adjusting rings, allowing precise blowdown adjustment. Designed for use in boilers, organic fluid vaporizers and pressure vessels. Available types SV44H Safety Valves have flanged inlet connections in accordance with ASME B16.5 and a test lever. The materials of construction are selected to meet the temperature and pressure characteristics of the process fluid. Applications Effective overpressure protection for boilers and generators, for steam systems downstream of pressure regulating stations, at the inlet of equipment such as heat exchangers and process vessels. Also for use in steam flash recovery tanks and in condensate return systems to protect accumulation vessels and equipment. Construction standard SV44H Safety Valves are designed and built in accordance with the ASME Sec.I, Sec.XIII and Sec.VIII and the materials of construction meet the requirements of these codes. Production tests are carried out in accordance with the requirements of items PG-73.5, 3.6 and UG-136(d) of these codes. Certificates A certificate of conformity is supplied with each valve including valve set pressure and hydrostatic test. Material certification is provided in accordance with BS-EN 10204 3.1 for all primary pressure containing parts.
