The valve with an internal spring for the Schrader mechanism (in a pack of 10) used in AVX service valves causes automatic blocking of the flow when the pusher does not press on the valve stem. The pressure of the pusher (e.g. from a service hose or connected capillary equipped with a pusher) opens the flow in both directions allowing the refrigerant pressure to be measured or recovered from the installation. Can work in systems with R12, R22, R134A, R404A, R407C, R410A, R507 , R290 refrigerants. Internal mechanisms are suitable for refrigerants HCFC, HFC and R744 (CO2).
