Discover the Different Types of Service Valves Used with R134A Refrigerant

Service valves used with R134A typically include low- and high-side couplers, liquid shut-off valves, and pressure relief and safety valves.

What Type Of Service Valves Are Used With R134A

Type of service valves with R134A are designed to control gas flow in refrigeration, air conditioning, and heat pump systems. They provide accurate control of flow, pressure and temperature. The two main types of service valve for R134a are high-side (suction) valves and low-side (discharge) valves.
High-Side Valves: A high-side service valve is designed specifically to control the flow from the compressor’s outlet port (high-side) to the evaporator/condenser assembly. High-Side Service Valves allow compressed Ru 134A refrigerant to be added, released or re-circulated within the system during a refrigerant recovery process or routine servicing and maintenance operations.
Low-Side Valves: Low-side service valves are used to provide a connection between the evaporator assembly and compressor inlet pressure port (low side). They allow liquid refrigerant to be removed from, recharged into, or recycled within the system while maintaining a set level of system pressure. Low side service valves also provide isolation of potential risks and providing protection against dangerous back pressure due to high side pressurization.
