The H-Series Motorised Valves, working in conjunction with time controls and thermostats, are used in domestic and commercial central heating, hot water and chilled water systems to control the flow of water in the system. These valves are developed to provide robustness, dependability and operating efficiency. Designed to withstand higher-thanusualtest pressures, support bearings at both top and bottom of the shoe and paddle spindles and tough polycarbonate actuator covers are some of the features which ensure this added quality.H-Series valves are normally purchased as separate valve bodies and actuators. Actuators are fitted to the valve bodies on site for convenience of installation and serviceability.Available as either rotary-shoe or paddle types. The range includes 2-port, 3-port diverter or midposition, metric sizes 15mm, 22mm and 28mm with copper compression fittings and imperial sizes 3/4” and 1” BSP threaded.
