On/Off Valves with Solder-Connect Fittings for Refrigerant
- Valve Type: Ball
- For Use With: Refrigerant
- Seal Material: PTFE Plastic
- Specifications Met: UL Listed, C-UL Listed, CE Marked
Install these valves in HVAC and refrigeration systems to control CO₂. They are operated with a wrench to give you the leverage needed to manage the flow of highly pressurized gases common in refrigeration systems. Because they require a wrench, these valves can’t be opened accidentally when bumped or snagged. Solder them to metal tubing for a permanent, leak-tight connection. To monitor pressure or fluid flow, attach a gauge to the port. The port can also be used to drain and divert liquid. These valves are full port, so they do not restrict flow.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.
