HL-20 HL-10 fine small electric valve. Fine small electric actuator HL-02 HL-03 HL-05 HL-10 HL-20 HL-40 HL-60 HL-100 HL-160 HL-200 electric devices, rotary actuators fully functional, with a switch type, adjustable type, etc., it is small, light weight, reliable performance, bearings and key components imported products, worm output integrated, eliminating the coupling, high clearance, driving accuracy, small hysteresis; high use of special copper alloy forging, strength, good wear resistance, aluminum die-cast housing, nice, small electromagnetic interference, installed at any angle, easy to use, corrosion and rust-free refueling. Has a double limit, thermal overload protection, good safety performance. There are a variety of full-time travel speed options, single-phase power-driven, simple external lines, in addition to internal TR adopts advanced digital technology and highly integrated modules, mechatronics design instruments, such as a computer or directly receive the output of 4 -20mADC or 1-5VDC standard signal, intelligent control and precise positioning of the electric valve. In addition we have an appearance inside the intelligent modules and intelligent modules for users to choose.
