ROTALOCK VALVES

The function of a Rotalock Valve is to provide a convenient

removable access and isolation point for service.

Applications

Rotalock Valves are widely used throughout the refrigeration and air-

Pressure Vessels. Henry Technologies' Rotalock Valves are suitable for use

with HCFC and HFC refrigerants and their associated oils, as well as other

industrial fluids non-corrosive to steel, copper and Teflon.
