Jiangsu Lan valve General Equipment Co., Ltd. specializing in the production of the part-turn valve actuators, actuator design, referred to as Q-type electrical equipment. The valve and turn it on, turn off or adjust the drive control device for butterfly valves, ball valves, plug valves and dampers, and so do 90 ° rotation of the valve. This series of electric remote control device can also be on-site operation. Widely used in electric power, metallurgy, petroleum, chemical, food, textile, paper, pharmaceuticals, water and sewage treatment and other industries. Seal is used in electric valve actuators used in seal oil seals, gear inspection content, prevent access to sand, dust, water vapor and other contaminants and lubricating oil leakage, and play a good seal. In the selection of seal material, you should take into account the material temperature range of adaptability to seal, compatibility, seal lip of the working medium to the rotating shaft rotates at high speed following property. The main requirement of the oil seal: sealing effect, high reliability, low coefficient of friction, easy to install, compatible with the medium to be sealed. Jiangsu Lan valve General Equipment Co., Ltd. has always been committed to the "leading technology, quality and efficiency, customer first, the undersigned about compliance" business philosophy. Valve actuators Accessories PT-3D-J-type control module is based on a three-phase AC power source AC380V accept DC4 ~ 20mA signal transmission from the PLC, DCS systems or other operator, the control actuators main technical features Input voltage range: AC340V ~ 420V. Three-phase three-wire, three-phase four-wire system are applicable. ? You can automatically correct three-phase power supply phase sequence and the correct implementation of the valve opening and closing control, users can easily access the actuator electric three-phase power. Input / output signals are through the optical isolation (withstand 2000V surge voltage). · Position feedback signal 4 ~ 20mA load resistance: 50Ω ~ 700Ω, Accuracy: 0.5%; third potentiometer adjustment technology greatly simplifies the adjustment process. Jiangsu Lan valve General Equipment Co., Ltd. specializing in the production of the part-turn valve actuators, referred to as Q-type electrical equipment. The valve and turn it on, turn off or adjust the drive device control, high gearing, for butterfly valves, ball valves, plug valves and dampers, and so do 90 ° rotation of the valve. This series of electric remote control device can also be on-site operation. Widely used in electric power, metallurgy, petroleum, chemical, food, textile, paper, pharmaceuticals, water and sewage treatment and other industries. Seal is in the closed valve actuators Oil seals prevent the ingress of sand, dust, water vapor and other contaminants and lubricating oil leakage, and play a good seal. In the selection of seal material, you should take into account the material temperature range of adaptability to seal, compatibility, seal lip of the working medium to the rotating shaft rotates at high speed following property.
