HRAR Regulating Valves

HRAR regulating valves are designed to regulate the medium flow with a cone on the underside of the valve disc. The stem sealing is provided by a threaded bush.

AWP regulating valves are designed for installation in the refrigerant circulation of industrial refrigeration systems. Actuation is by hand wheel or ratched. These valves are both regulating and shut-off valves. Rotating the stem clockwise will lower the valve disc onto the valve seat and therefore close the pipe, counter-clockwise rotation will lift the valve disc and open the pipe. The regulating function is enabled by a cone on the underside of the valve disc. The maximum diameter of the cone corresponds to the valve’s nominal diameter. The stem sealing is provided by a threaded bush with spring-elastic PTFE ring. The valves are also equipped with a back seal so that when the valve is fully opened it is possible to replace the threaded bush and the seal.
