Can be assembled on the rotary type of valves, likes stainless steel (SS316/SS304)/ plastic butterfly valves, ball(double union) valves, and high performance double eccentric butterfly valve or any kind of rotary 0°-90° operation valves.
- IP67 rated waterproof and dustproof enclosure.
- Aluminum Alloy / Plastic (2 kinds) enclosure.
- JH Electric Actuator provides direct mounting on ISO 5211 valves.
- Voltage: AC110V/220V, three-phase AC380V/440V
- JH Rotary Automatic Electric Actuator (On/off series)
- Be used in the normal situation.
- JH Rotary Automatic Electric Actuator(Frequent-working and Fail Safe series)
- Provide the DC motor that would not be overheated, low consumption, large torque.
- The switching spped is smooth, and it can avoid the water hammer.
- DC motor, but the rated voltage: AC110V/220V, optional voltage: DC24V
- JH Rotary Automatic Electric Actuator(Modulating Controller series)
- This series has a wave interference filter to lower the impact of EMI and EMC.
- Input Signal(Standard): 4-20mA or 2-10VDC
- Output Signal: 4-20mA or 1-5VDC / 2-10VDC(Choose one)
- The output signal can be adjusted to control the error within 1mA.
Extra Limit Switch: to be used feedback the position signal
Heater: Can make inside temp. of electric actuator higher and dryer to prevent from the damage to the electric actuator caused by the frozen of lube oil or the moisture.
* It’s not recommended to install the heater when the temp. is over 35°C/95°F.
Rotary automatic electric actuator are using for Stainless Steel and Plastic Butterfly Valves and Ball Valves. It’s used in Petrifaction, Steel making, Chemical industry, Paper Industry, Power plant, Air separation plant, nuclear plant, waste water treatment, Dry gas, pure water system, cooling water system, Ultra-clean CDA gas, piping system, and Fire-fighting system.
1. IP67 rated waterproof and dustproof.
2. Made of Nylon which has purpose of resisting against heat, acid, alkali, waterproof, and dustproof.
3. Optional: Aluminum Alloy.
1. Please turn power off before manual operation or for maintenance to avoid parts broken or danger. When manual operating, 8m/m (not exceeding 10m/m) open and wrench, is recommended to use. Turn slightly firstly, and check whether it is turned too tightly to avoid valve deadly locked. Do not turn it brutally to prevent internal machine parts broken or damage.
2. Check waterproof O-ring and cable gland are secured tightly after wiring to prevent dusting or water contamination. (Suggested Minimum wire thickness is above 6 Ø.)
3. When more than one electric actuator is needed to operate simultaneously, please connect with the individual cables or installing independent relay for each actuator.
4. When manual operating, please note the position indicator cannot exceed scale marking range to prevent internal machine parts damage. (Modulator: Variable resistor impaired)
