AWP shut-off valves are designed for the installation in the refrigerant cycles of industrial refrigeration systems. These shut-off valves are operated by an electric actuator. They are shut off clockwise and opened counter-clockwise. The valves are fitted with a back seal. When the valve is fully open, it is possible to replace the screw bush and the seal. Electric actuated shut-off valves are available with a metal bellows to ensure a complete hermetic sealing.
