VG1000 Series electric valve Product Overview: Application Features: 1, widely used, can have the same diameter valve flow coefficient Kv multiple options. 2, adjustable flow 500: 13, long life design, there are graphite reinforced PTFE valve seal. 4, built-in-one disc with the flow, not afraid of pressure again. 5, 6 double EPDM stem seals, high off the force, rated working pressure, maximum working pressure 7, VG1000 Series Ball Non-Spring Return Electric Actuators with manual operation button for heating, ventilation and air conditioning systems. According to the requirements of the controller, hot water or chilled water and saturated steam flow rate can be adjusted. This series of valves from caliber DN15-50, there is two-way and three-way valve types. Johnson Controls can match inelastic reset and spring return actuators to achieve on and off, and the proportion of floating-point control, valve and actuator can be pre-assembled or installed in the field in the production plant.
