Automatic Valves for manufacturing - SIO

Automatic Valves

SIO can provide you with automatic valves that come with different materials and functions. Automatic valves are useful in a wide range of applications. Their mechanism is a spring-loaded cartridge. The cartridge will absorb the pressure that is typically caused by alterations in the flow. These conditions are regulated by the control valve.

These control valves are commonly used in air handling equipment, towers, chillers, baseboards, pumps, cabinets, and terminals among others. The type of automatic valve will depend on where it is used. For example, small automatic valves are effective in cabinets, terminals, and baseboards. Meanwhile, large automatic valves are ideal for towers, chillers, and pumps.

You can be confident that SIO will help you with all your needs and configurations for automatic valves.

    Manual valves are cheaper as compared to automated valves. But automated valves are required in fewer quantities comparatively. They are installed in lesser terminals than manual valves, thus becoming more cost-effective.

    Better Control

    The process using automated valves does not require constant supervision and works well even when there are variations in pressure. They ensure a constant flow and provide better balance control.

    Easy to Install

    Automatic valves are easy to install and can be accessed easily for maintenance. They also require less maintenance than manual valves.


    Automatic valves save time as no manual intervention is necessary. Because of little to no manual supervision, they also save labor costs.

    Standard and Specification of Automatic Valves

    The following standards should be present in the ball valve you are going to buy for industrial purposes-

    An automatic valve should have a quick response time. Rapid response is necessary to avoid accidents and process failure.

    Automatic valves should allow only unidirectional flow. They should be equipped to prevent backflow in any case.

    Material that can handle abrasive fluids and prevent wear should be used for the construction.

    The ability to open at a pre-set pressure and prevent damage to the equipment is a must in automatic valves.

    API and ASME-certified gate valves and globe valves manufactured as per BS and ASME standards are considered best for industrial use.

    What are the different types of automatic valves?

    Automatic Drain Valve

    Automatic Drain Valve

    Commonly used in compressed air systems, automatic drain valves remove water from storage and process lines. An automatic drain valve removes the need to manually remove the water. It drains the water automatically based on the condensation level or as per the schedule.

    Automatic Vent Valve

    Automatic vent valves are also known as air release valves. The air trapped in a heating system is automatically released through the vent valve. When the increased float force is more than the internal pressure, the vent valve would open.

    Automatic Flow Control Valve

    Automatic flow control valves are responsible for regulating the rate of fluids and pressure in a pipeline . They maintain the flow rate even when the pressure in the system changes. Butterfly and pneumatic globe valves are mostly preferred for these applications.

    Automatic Relief Valve

    Automatic relief valves are safety valves. They prevent accidental fires, equipment failure by controlling the pressure in the system. An automatic relief valve opens at a predetermined pressure level to protect the system. They are used in high-pressure gas systems.

    What are the different types of valves that can be automated?

    ball valve with actuator 300

    Ball Valves

    An automatic ball valve, a quarter-turn valve, functions with the help of an actuator and requires an external power source, such as compressed air or electricity, to operate. They are efficient and provide a tight seal. They are suitable for application in oil and natural gas plants, wastewater treatment facilities, etc.


    Butterfly Valves

    An automatic butterfly valve, a type of quarter-turn valve, uses an electric or pneumatic actuator to function. These valves are lightweight and can fit into small spaces. Common applications include the chemical industry and slurries.

    Diaphragm valve with pneumatic actuator

    Diaphragm Valves

    Automatic diaphragm valves come with a flexible disc called the diaphragm. The diaphragm comes into contact with the seal to shut off. These valves are suitable for the pharmaceutical and food and beverage industry because of their stellar contamination prevention abilities.


    Plug Valves

    Another type of quarter-turn valve, automatic plug valves, is incredibly flexible and uses the plug to regulate the media flow. They are commonly employed in petroleum pipelines, chemical processing, and low-pressure settings.


    Needle Valves

    Automated needle valves use their pointed end to seal the flow. They allow for precise regulation of media flow. The smooth mechanism of the valve has made it useful in industries, such as power generation plants and gas dispensation processes.

    Pilot-operated solenoid valve

    Solenoid Valves

    Solenoid valves have a built-in actuator that is operated by electricity. They can control the flow and direction of the media and are compact in design. Industrial applications, such as automatic irrigation sprinkler systems, use them because of their reliability and fast switching.

    Globe Valves

    SIO manufactures various automatic types of globe valves according to BS and ASME standards to ensure they provide optimal performance and ensure positive and precise sealing. They are mostly used in high-pressure systems for throttling and isolating.


    Gate Valves

    Automatic gate valves, a type of linear motion valve, have a flat disc that moves to open and close the path of flow. Automatic gate valves are widely used in the automotive industry and applications that handle viscous fluids.

    Methods of Valve Automation

    There are broadly three methods of valve automation. An automatic control valve is opened and closed by these three methods.

    Electric Valve Actuator

    An electric valve actuator is a cost-effective and non-toxic method of valve automation. It uses electricity as a power source to control the actuator. An automatic control valve using electric valve actuators functions precisely and quietly.

    An electric linear actuator is an electrically-powered linear actuator that consists of drive mechanisms, motors, and linear guides. These components are used to transform electrical energy via mechanical transmission, thermal expansion, or electromagnetism to generate a straight motion.

    An electric rotary actuator is an electrically-powered mechanical device that is made up of motors and shaft mechanisms with controlled rotary motion. These are used to change electrical energy into rotational motion to change the position of the valve.

    Pneumatic Valve Actuator

    Pneumatic Valve Actuator

    The pneumatic valve actuator operates using gas or compressed air pressure. It has a higher closing force than other methods and is suitable for applications, such as high-pressure systems, industrial pumps, etc.

    A diaphragm actuator has a thin and flexible membrane called a “diaphragm” that actuates a valve using compressed air. It can either be direct-acting (spring-to-react) or reverse-acting (spring-to-extend).

    A piston actuator is often used in applications where the stroke of a diaphragm actuator is too short or the thrust is not enough. It uses compressed air that is enforced to a solid piston enclosed in a solid cylinder.

    Hydraulic Valve Actuator

    The hydraulic valve actuator uses fluid pressure to operate the valve. The fluid pressure is converted into motion. They are widely used in the automotive industry and water pumping stations.
