Check Valve, Ball Valve & Globe Valve for Refrigeration Pipeline
Check valve (one-way valve): allows refrigerant flow only in one direction, prevents reverse flow when pressure reverses. Typical application: hot gas defrost return line, parallel compressor discharge manifold, avoid high pressure gas backflow. Spring check valve is used for refrigeration system; low cracking pressure type for low flow circuit. Ball valve: full bore, small flow resistance, used as maintenance isolation valve, for refrigerant circuit cut-off during overhaul. Globe valve: fine throttling capability, big flow resistance, used for manual balance adjustment of oil return or hot gas branch. Xiteliduo rack system configures ball valve at inlet/outlet of each circuit for convenient single-circuit maintenance. Check valve cannot be installed horizontally in some low-temperature oil circuit; wrong orientation leads to oil accumulation. Ball valve is not designed for flow regulation; long-term half-open position will damage sealing ball seat. All refrigeration valves must match refrigerant and pressure grade; ordinary water valve cannot replace refrigeration dedicated valve. Refrigeration maintenance & repair company uses ball valve to isolate faulty circuit, keep other cold room circuits running.
FAQ
- What is check valve? One-way valve, block reverse refrigerant flow.
- Where is check valve widely used? Hot gas defrost pipeline and parallel compressor discharge.
- What is ball valve mainly used for? Isolation cut-off for maintenance.
- Can ball valve be used for long-term flow throttling? Not suggested, easy to damage sealing seat.
- What valve is suitable for fine manual flow adjustment? Globe valve.
- What spring check valve parameter matters for low temp circuit? Low cracking pressure.
- Can water pipeline valve replace refrigeration valve? Forbidden, pressure and medium mismatch.
- What benefit of independent ball valve per circuit? Isolate fault circuit without shutting down whole rack.
