Valve actuators can bring many benefits to an operation, including reduced maintenance costs, increased uptime and better safety. There are many more benefits and reasons why you should use an actuated valve, so continue reading our helpful guide to discover the top five reasons to invest.
The primary objective for an actuated valve is to move a valve into an open or closed position. It attaches to and works in conjunction with two parts: the valve pilot and the valve body.
As manufacturers crave for more productivity and efficiency, the need for actuated valves has become more important. Here are five reasons why you should use an actuated valve for your application:
Actuated valves allow for greater control and visibility of a system. If using a Programmable Logic Controller (PLC) or Distributed Control System (DCS) type system, it’s easy to communicate with valves and get a feedback signal to confirm that they’re in the position needed. When valves are manual, the door to operator error is left open.
The ability to remotely control a valve allows operators to stay safe. An actuated valve lets operators keep away from extreme hot and cold temperatures. It also allows them to stay clear of hostile environments, such as those with noxious gases.
In an emergency situation, an actuated valve goes into fail safe positions, whether that’s fail open or fail close. Pneumatic actuator valves will use a spring return, while an electric actuator valve has a back-up battery to allow for fail safe positioning.
A valve actuator takes one more thing off the mind of an operator when an emergency occurs.
When an actuator valve is involved, there are a great deal of cost-savings to be had for manufacturers. The operator is always in contact with the valve actuator. This ensures that the valve is open to just the right percentage, avoiding any wastage that would lead to an increase in costs.
When a valve is manually operated, there is a risk not only of wasted materials but of potentially ruined product due to manual operational errors.
Actuated valves are brilliant when valves can’t be easily reached manually. Whether that valve is located high above or down too low, if it’s actuated it can be remotely controlled.
This is another aspect of the safety that actuated valves can bring. It gives operators easier control of the valves and stops them from potentially risking injury by trying to control hard-to-reach valves.
Large valves can be difficult to close with a manual wheel, while fluid viscosity and velocity can have an impact on how much torque is needed to close the valve. Requiring operators to close large valves with manual wheels against rushing water is going to cost a lot of man hours and cause a decrease in productivity. It may also increase the risk of injury.
Setting up a valve with the appropriate valve actuators can make sure you have the right amount of force to turn or lift the valve every time.
Automation in the process industry is increasingly commonplace these days because actuators enable valves to operate with ease and reliability.
BM Engineering stocks quarter-turn actuators, which suit (but are not limited to) our ball valves and butterfly valves. We have the ability to add control and indication features, such as position feedback and Namur solenoid valves.
We also have in-house testing facilities for AS-i, Exi and 4-20mA control valves. Various other types of actuated valves are also available on request, such as angle seat valves, globe valves, diaphragm valves, 3-way valves, and electric actuated valves.

1. Miniaturization of components: The actuator control panel uses micro-chip electronic components imported from Motorola, Maxim, etc. of the United States. These components were originally developed for aerospace and military equipment. They are small in size, light in weight, powerful in function, and highly reliable. We chose micro-chip electronic components to enhance the function of the positioner and improve it. Precision and reliability.

2, no need to block the module: the input signal and output signal of the actuator control board have a common reference to the grounding point, when the system is connected, there is no need to block the module.
3, can be applied to the DCS system: the actuator control board has the "ready" and "inductive alarm" control signals required by the DCS system; the "digital pulse" signal can be superimposed on the DC circuit system in the current loop of 4 ~ 20mA .
4. Break signal maintenance: The actuator control board adds the signal maintenance function. If the signal line of the early stage external input is broken, the positioner makes the electric actuator “full open”, “full off”, “stop in place” and “ Stop the position", continue to work after the fault is removed.
5. Electrical limit: The actuator control board adds the electric limit function. It is assumed that the automatic control signal (one external signal or manual signal) is out of range (less than 4 mA or greater than 20 mA). The positioner constrains the electric actuator output angle to not exceed the range. To prevent damage to the valve, together with upper and lower limit indication.
6. Anti-power supply sudden change disturbance: The actuator control board adds the function of anti-power sudden change signal disturbance, which constrains the strong current caused by the large rational electric appliance on the power supply line to start or stop. Misunderstanding.
7. Customary positive effect and counter effect: GAMX-2K electric actuator is set to positive effect at the factory, that is, 4mA corresponding valve is fully closed, 20mA corresponding valve is fully open, assuming the user requires counter effect, no need to use electric soldering iron to solder potentiometer Wire and head wiring, as long as the positioner board is simple to set.
8, custom single-phase and three-phase operation: actuator control panel can be used to single-phase and three-phase operation, can control single-phase motor through solid state relay, can also control three-phase motor through relay and contactor.
9. Super-torque maintenance: The actuator control panel has super-torque maintenance function, which can prevent the damage caused by the overload of the actuator. When the super-torque maintenance, the motor stops rolling and insists on the output orientation. Only when the actuator is reversing can it be unlocked. , exit the super torque maintenance condition.
10. Electric brake function: The electric actuator control panel has electric brake function. When the servo is in position, the motor is powered off. However, because the mechanical inertia causes the actuator to continuously roll, it constitutes idle travel. The electric brake function can eliminate the idle phenomenon and improve the handling precision.
