2 Way Valve Pro Manifold Set ( R22,134 404 & 407 )

The Valve Pro control valve allows you to make an un-pressurised connection to the system, removing the risk of refrigerant loss and also reducing the potential for refrigerant burns.
Once connected, you can use the control valve to open or close the schrader valve to carry out your service work
When you have finished, close the control valve. This will isolate the system and seal the charging hose, allowing you to safely remove the charging line.
