Specifications: Drive motor: Hysteresis synchronous motor drive Operating voltage: 200VAC, 50Hz / 60Hz (with AC24V, 110V to choose from) Power consumption: ≤ 5.7VA Valve body pressure: 1.6MPa Allowable pressure: ≤ 0.12MPa Applicable medium : Cold water, hot water Medium temperature: 2 ℃ -95 ℃ Ambient temperature: 0 ℃ -60 ℃ Opening and closing time: about 10 seconds, about 5 seconds off Installation and commissioning: Before installation must read the instructions, cut off the power and Must be installed by professional and technical personnel. The flow direction must be the same as the direction of the arrow on the valve body. The valve body must be above the coil water tray to ensure that dripping falls into the water tray. The valve body and actuator must be mounted within ± 60 ° C vertical and at least 30 mm above the space for disassembly. With the surrounding pipelines, equipment, buildings must maintain sufficient space for maintenance operations, must be installed in the maintenance personnel through the manhole to reach the place. The valve body can be installed after pressure test and pressure test. If the actuator is already attached to the valve body, never apply force to the actuator during installation and commissioning as this may damage the actuator. After installation and check the correct, power debugging. At a minimum, observe the three full drive cycles and verify that all components are correct. After passing through the anhydrous test, pass the water test. The system pressure on the water must be strictly controlled within 0.15MPa, to ensure that the electric control valve on the effectiveness of the water switch. Scope of application Air-conditioning, heating, ventilation, domestic hot water and other civil system-level chemicals, petroleum metallurgy, electric light industry Industry production process of automatic control.
