Access control valve SUPER STARS ST-VC2
Angle Service Valve SUPER STARS ST-VC2 – Low-Loss Charging
Professional service valve for low-loss charging and recovery of HVAC and refrigeration systems.
The SUPER STARS ST-VC2 is an angled service valve designed for low-loss charging and evacuation of refrigeration and air conditioning systems using refrigerants such as R410A, R32, R290 and others commonly used in HVACR. The valve is equipped with a 5/16" SAE female thread (system side) and a 1/4" SAE male thread for connection to a service hose.
By turning the control knob, the internal plunger mechanism opens the system access valve, allowing controlled refrigerant flow to or from the service hose. This design significantly reduces refrigerant loss during charging or recovery operations, in accordance with European regulations aimed at reducing F-gas emissions.
Key Features
- Low-loss charging – minimizes refrigerant loss during service operations.
- Angled design – ideal for confined or hard-to-reach service ports.
- Plunger mechanism – precise opening of the system access valve.
- PTFE (Teflon) seals – excellent chemical resistance and durability.
- HVACR compatibility – suitable for modern systems using R410A, R32, R290.
- Professional-grade construction – designed for intensive service use.
