Actuator Enclosure

The anodized aluminum enclosure with powder coating is highly corrosion-resistant and explosion-proof. Standard with IP67 protection and IP68 available as option.

Motor

Fully enclosed squirrel-cage motor with compact size, large torque, little inertia force and F class insulation rating. Built-in overheat protection switch avoids damaging of the motor.

Manual Handwheel

The compact and convenient handwheel would be used to operate the valve on/off when the actuator power off. Pulling the clutch to right side and then the handwheel could be operated. When the actuator power on the clutch would return to left side automatically.

Position Indicator

Installed on the top center for observing the position of valve. The convex lens design avoid condensation of the water.

Heater and Thermostat

To heat the actuator space in cold environment which let the actuator workable at a wide temperature range and protect the motor and the parts out of the

damage.

Limit Switch

Both mechanical and electronic limit switch equipped. Mechanical limit screw is adjustable, safe and reliable.

Electronic limit switch SPDT controlled by the cam. Position of limit switch can be set accurately and conveniently by an easy adjustment.

Torque Switch

The built-in and preset torque switch provides overload protection (Except type

UED-050/100) and to make the the valve and actuator out of damage by cutting

off the power supply automatically when the valve is jammed.

Long Life and Maintenance Free

Precise worm gear transfer large torque efficiently with low noise (max. 50 dB) and long life. The self-lock function prevents inversion and insure stability and reliability. High effective lubricant oil has been filled in before the actuator dispatch which keep the actuator running during the life circle.

Installation

The flange fitting the valve at the bottom of Electric Actuator meets ISO5211 and DIN3337 standard. The actuator can be installed vertically or horizontally.

Analog Signal and Bus Control

The analog signal and bus control offered by a separate module attached to the actuator by fixing screw with inner cable tunnel. Such design would be help for the control part out of the motor heat and electric interference.

Fail Safe

UED Series supply fail safe function as option that the actuator would be driven by a built-in battery to operate the valve open or close when the power off.

Hydraulic Power Unit (HPU)

---

The principle of the Hydraulic VRC system is that pressurized oil, generated by the power pack, is used to open or close the valve by means of the solenoid controlled actuator.

Hydraulic Power Unit (HPU)  consist of oil reservoir, hydraulic pumps, electric motors, control panel, electric components and accumulators etc…

All components are selected to ensure high reliability and compliance with Class requirements.

Hydraulic power unit is designed to minimize pipe arrangement and easy maintenance.

The capacity of oil tank, motor, pump and accumulator is defined by the total volume of actuators and the largest size of actuator connected with the highest torque of valve.

In order to keep the adequate capacity of the accumulator, the power unit delivers the higher working pressure than the designed working pressure of VRC system.

The accumulator has three main purposes;

1. to provide the reasonable time interval between start and stop of pumps by the compensating of the internal leakage in VRC system during the time given by the customized requirement.
2. to secure the constant oil pressure
3. to guarantee the complete operation of the specified valves which are clarified by the cleent’s request under an emergency situation

Standard components:

• Level switch for low oil level
• Oil level sight glass with temperature gauge.
• Remote start/stop operation.
• Potential-free output for power on, pump running, thermo failure and low  oil pressure in motor starter box for external use.
• Selector switch (between service and stand-by motor).
• Motor load indicators
• Remote system pressure option
• Hour counter
• Accumulator with classification
• Tank, frame 150/260l
• Fittings: Filter element output / return
