VTMR Series Spring Return Electric Actuator

The VTMR series spring return electric actuator utilises a spring-driven pinion and rack mechanism, offering torque capacities between 50Nm and 300Nm. Operating under standard power conditions, this actuator features a motor-driven system that also charges the spring. Should there be a power failure, the spring discharges its stored energy, promptly activating the actuator to return the connected devices to a secure state, either fully open or closed. This ensures a smooth and stable operation, effectively preventing any sudden pipe bursts (hammer-blow effect).

Body Materials: Nylon, Spring Steel, 34# Steel, 40CR, Tempered Glass, Ceramic, Q235, & Bearing Steel
Certifications: ISO 9001:2015, SGC MD 2006/42/EC, & DNV
Working Temperature Range: -25°C to 65°C
Safety Integrity Grade: SIL2
Torque Range (NM): 50 to 300

Frequently Asked Questions

A valve actuator is a mechanical device used to control the opening and closing of valves, allowing for remote or automated operation.

Actuators can be used with various types of valves, including ball valves, butterfly valves, gate valves, globe valves, and plug valves, among others.

The main types of valve actuators include pneumatic actuators, electric actuators, hydraulic actuators, and manual actuators.

A pneumatic actuator uses compressed air to generate mechanical motion, which is then used to operate the valve, either by opening or closing it.

Electric actuators offer precise control, easier integration with control systems, and do not require a constant supply of compressed air like pneumatic actuators.

Factors to consider include the type and size of the valve, operating environment (temperature, pressure, hazardous conditions), control requirements, and available power sources.

Yes, there are valve actuators specifically designed for hazardous environments, such as those with explosive atmospheres, which comply with industry standards for safety.

The size of the actuator depends on factors such as the torque or thrust required to operate the valve, which can be calculated based on the valve size, pressure, and flow conditions.

Yes, many valve actuators are designed for easy retrofitting onto existing manual valves, allowing for automation without the need for valve replacement.

Regular maintenance includes lubrication, inspection of mechanical components, and checking for leaks. Troubleshooting may involve checking electrical connections, pneumatic systems, and control signals.

Yes, valve actuators can be equipped with various control options, including remote control through wireless or wired networks, as well as integration into SCADA (Supervisory Control and Data Acquisition) systems.

Valve actuators are used in a wide range of industries and applications, including oil and gas, petrochemical, water treatment, HVAC (heating, ventilation, and air conditioning), pharmaceuticals, and food processing, among others. They are essential wherever automated flow control is required.
