A28H Safety Valve, A28H Spring Full Lift Safety Valve A28H-16Q A28H-16C A28H-25C A28H-40C A28H-16P A28H-25P Boiler Air Tank Steam Relief Valve

**A28H safety valve** is spring full lift safety valve. **A28H safety valve** adopts external thread connection with manual lifting wrench for on-site valve test, full-lift design for large discharge capacity. Suffix Q of A28H = QT450 ductile iron body, suffix C of A28H = WCB carbon steel body, suffix P of A28H = 304 stainless steel body. H seal surface Cr13 hard alloy, wear and erosion resistant with stable sealing performance. **A28H safety valve** suitable for saturated steam, compressed air and water, max working temperature ≤200℃. When pressure inside boiler, air compressor tank or pressure vessel exceeds set pressure, A28H safety valve fully opens rapidly for pressure relief and auto closes once pressure drops to safe range. **A28H safety valve** widely used for small steam boiler, air compressor tank, heat exchanger, low pressure vessel and pipeline. A28H safety valve complies with GB/T12243, GB, JIS, ASME standards, custom A28H set pressure available.
