Characteristics
This forged lift check valve is integrally forged from A105 carbon steel or F304/F316 stainless steel with dense internal structure free of sand holes. The guided lift disc realizes reliable backflow prevention. With high temperature and pressure resistance, metal or PTFE sealing options, it is widely applied in petrochemical, power plant, hydraulic and high-pressure steam small-bore pipeline systems.
Advantages
1.Forged body of high performance check valve with compact internal structure eliminates sand holes and pores, outstanding pressure and explosion resistance for long-term stable service under high temperature and high pressure.
2.Superior temperature and pressure resistance compared with cast valves, specially designed for petrochemical, power plant, high-pressure steam and hydraulic pipeline systems.
3.Compact small-size design fits narrow instrument and unit space, easy disassembly and independent seal replacement to cut maintenance cost.
Packing
Standard export wooden case packaging
Application Scenarios
This lifting type check valve is widely used in petrochemical high-pressure process pipelines, power plant steam instrument lines, high-temperature heat transfer oil systems, hydraulic equipment matching pipes, natural gas small pipelines and fine chemical anti-corrosion high-pressure lines.
