Offering Safe & Reliable Service Access to Refrigerant Cycles
The Dunan series of high quality charge valves is known for its long-lasting durability whilst offering a safe and reliable way to access the refrigerant cycle for maintenance and repairs. They offer versatility and can be used in systems using both older and newer refrigerant types.
Air Tightness
Featuring a combination of soft seal and hard seals to ensure airtightness.
Refrigerant Compatibility
Dunan charge valves offer compatibility with various refrigerants, including R134a, R407C, R410A, R32, and R404A, R290.
Evacuate, Charge or Adjust Refrigerant Levels During Maintenance or Repair
The charge valve is an essential component in any refrigeration system, offering a secure and precise way for technicians to evacuate, charge, or adjust refrigerant levels during maintenance or repair. It also serves as a reliable access point for connecting gauges to monitor system pressures, which is critical for diagnosing issues and ensuring optimal performance. Without a charge valve, accessing the refrigerant circuit would require cutting into the lines, a time-consuming, wasteful, and inefficient process, making this component indispensable for convenience and system integrity.
FJT Series
The FJT series of refrigeration charge valves are designed especially for this check. They are especially designed for filling and recharging with refrigerants and monitor the pressure of HVACR systems. FJT charge valves feature a combination of both soft seal and hard seal to ensure airtightness.
