Features HANLKA excellent technical performance multiple agencies arbitrarily selected temperature compression sleeve structure balancing valve plug to avoid the application of electric leakage sleeve valve, the sleeve valve equipped with PS, 3810, ZAZ, DKZ series electric actuators composed . Within the electric actuator servo system, without reprovision servo amplifier has an input control signal (4-20mADC or 1-5VDC) and single-phase power to control the operation to achieve the pressure, flow, temperature, level and other parameters adjusted . Adopts balanced valve plug structure, with good valve plug stability, easy to produce vibration, low noise sensitivity, allowing the use of pressure large, simple connection, which is widely used for flow coefficient, leakage power requirements more stringent , metallurgy, petroleum, chemical industry, light industry, industrial automatic control system.
