Electric drives
The use of electric actuators increases safety, reduces maintenance costs and ensures rapid response to changes in technological processes. The UKSPAR catalog presents reliable electric actuators for working with shut-off valves in industrial and municipal systems.
UKSPAR electric actuators catalog
UKSPAR offers electric actuators that have been tested for reliability and compatibility with various types of valves. The range includes both multi-turn models for gate valves and quarter-turn models for ball valves and butterfly valves.
The drives are equipped with limit switches for signaling extreme positions, a manual override mechanism and have a high level of protection. Explosion-proof versions are available for the oil and gas and chemical industries.
How to choose an electric actuator for your valves
When choosing an electric drive, the following should be considered:
- type of valve (gate, tap, disc valve);
- required torque;
- operating conditions (temperature, humidity, explosive environment);
- control method – reversible, modulating or with limit switches.
For valves, a multi-turn actuator is optimal, while for valves and gates, an angle actuator is optimal. UKSPAR helps you choose a solution that will ensure the reliability and durability of the system.
Types of electric drives
The internal architecture and kinematic scheme of the devices differ depending on the logic of the movement of the valve body of the valve on which they are installed. On this basis, the equipment is divided into two large categories.
Angled — for taps and valves
This is the most common type for quarter-turn valves. The electric actuator for the valve turns the shaft exactly 90 degrees. It is ideal for ball valves, disc valves and three-way mixers. The mechanism is compact and provides high output torque at low speeds.
Multi-turn — for latches
A gate valve actuator performs many revolutions of the output shaft to complete an open-close cycle. This type of actuator is required for valves that use a screw pair (spindle-nut) to move wedge and gate valves. Multi-turn actuators develop high torque to operate large, high-pressure valves.
Compatibility with fittings
The key factor for successful automation is the correct connection of the electric drive to the valve. To do this, it is necessary to coordinate:
- Connection flange type according to ISO 5211 standard.
- The shape of the armature shaft shank, which is inserted into the corresponding hole in the actuator.
- Direction of rotation for opening and closing.
At UKSPAR you can order ready-made solutions – electric actuators, fully configured and mounted on your valves.
IP protection rating and explosion-proof design
Drives often operate in harsh environments. Standard models have an IP67 or IP68 protection rating. They are completely dust-tight and can withstand temporary immersion in water.
For facilities with explosive atmospheres, such as gas boiler rooms or chemical plants, we offer explosion-proof designs. Their housings prevent sparks from escaping to the outside. The sealed cable gland additionally fixes the wires.
Integration into automation systems
Modern electric drives are not just actuators, but full-fledged elements of automated control systems (ACS TP).
SCADA, dispatching, manual duplication
UKSPAR electric drives support connection to dispatching and SCADA systems, which allows for remote monitoring and control of technological processes.
To increase reliability, many models are equipped with a manual backup function, which makes it possible to control the valves even in the absence of power supply.
