| Message: | Intelligent Multi Turn Electric Modulating Actuator IP68 For Controlling Gate Valve Yangzhou Hengchun Electronics Co., Ltd. is a new high-tech enterprise focusing on researching, developing and producing intelligent electric actuator for over 15 years. Our products are suitable for butterfly valve, ball valve, gate valve and check valve etc. It is widely been used in power industry, metallurgy industry, oil industry, chemical industry, water treatment industry and other machinery industries. The actuators accepts 4-20mADC input signal to achieve position and process control, and use an absolute type, linear position sensing device provides 4-20mADC valve position feedback. Analog input signal with electrical isolation, short circuit protection, open circuit detection, and can be non-polar connection, user-friendly field wiring and commissioning. The control module uses solid state starter for three-phase or single-phase power supply, meet at least 1200 starts / hour requirement.●accuracy: ± 1%●linear: ± 0.5% (relative to the full trip)●deadband: 0.3% to 5%, adjustable in 0.1% increments (factory default setting: 0.8%)●delay time: 1 second●input impedance: 300Ω●drift: |
