GIA male valve for air conditioner 1/4:
Especially developed for split air conditioning systems and heat pumps in which repeated coupling / decoupling of the stop valves is only expected sporadically (see technical data - up to 75 times)
The unique design enables the stop valves to be properly and correctly coupled without the use of torque wrenches and prevents inadvertant uncoupling.
Repeated coupling and decoupling without evacuation / refilling of components and without lengthy interruptions to the functions of the refrigerant and air conditioning systems.
Industrially manufactured flare connectors rule out errors during assembly and guarantee high reliability and minimal leakage rates.
Reduction of effort in case of guarantee or warranty or at the replacement of components.
Saving of time and technical equipment at installations of new facilities as well as at the maintenance.
Preventing the often complete refrigeration loss in case of an improper disassembly or maintenance by not certified persons or enterprises (cf. VO (EU) no. 517/2014).
The European standard 378 for refrigeration systems and heat pumps requires in part 2 a sufficient number of stop valves in order to reduce the risk of loss of refrigerant to a minimum. Companion valves of Generation I consist of a pair of mating self-closing stop valves. Their use reliably prevents the escape of refrigerants, especially during maintenance.
Generation I companion valves meet the requirements of Regulation (EU) No. 517/2014 on fluorinated greenhouse gases with regard to maximum permissible leak rates of up to 70 couplings and uncouplings.
Seals made of Hydrogenated Acrylonitrile Butadiene Rubber (HNBR) ensure a wide temperature range and good chemical resistance to refrigerants and refrigeration oils.
Male stop valves with SAE internal threads for flared joints with pressed-in copper sealing ring
and female stop valves with soldering sleeves for pipes with inch diameter.
