Air/Electric Actuated Valves are the traditional solution for most industrial applications due to their versatility, long term seat tightness, high strength materials and robust construction.

They are mainly used for regulation purposes, due to the normalization of the flow characteristics when used for this purpose. Typical application examples are temperature, pressure, flow and level control. However, there are many more applications if you want to automate production.

Pneumatically actuated/electrically actuated valves are used in almost all industries, such as chemical and petrochemical, food and pharmaceutical, water treatment, as well as in the automation of textile, food, packaging equipment.

One of the elements that must be installed in the system for transporting various media is control valves, which maintain the stable operation of the units. Control valves are becoming an increasingly important component of modern manufacturing throughout the world. Properly selected and maintained control valves increase efficiency, safety, economy and environmental friendliness.

Modern factories use an extensive network of control loops to produce the final product. These control loops are designed to keep process parameters such as pressure, flow, level, temperature, etc. within the required operating range to ensure a quality end product. Control valves are designed to change the amount of flowing medium in the process control system, pressure regulation, as well as the distribution and mixing of flows.

The Artesia company offers reliable control valves made of steel and gray cast iron, flanged, welded and threaded connections, with a diameter of 10 to 700 mm and a pressure class from PN16 to PN630. The range of application of products is very extensive, including the industrial sector and the domestic sphere. Of particular interest is the direction associated with high pressure and temperature.

To control the technological parameters and the flow of the transported medium as a whole, it is possible to use a control valve with an electric drive - a narrowing unit with a variable capacity. Structurally, such fittings can be with one and two saddles, as well as two- and three-way. The control valve with an electric drive of the first type is endowed with 1 gate, and the second - with 2, which operate in parallel and are located on an identical axis. As for the two-way ones, they are equipped with a pair of pipes (standard design, presented in our online store). Three-way have, respectively, 3 outlets.

Characteristics of electrically actuated control valves

The Artesia company offers flanged two-way fittings made of steel and gray cast iron, which are suitable for operation with gas, liquid, water, air, steam and other compositions without abrasive additives, comparable to the material used to manufacture the internal parts of the equipment.

It is possible to install control valves with an electric drive on pipelines DN 15-150 mm. They block the flow of transported substances by means of a movable component - a plunger. This part is made in three versions: needle, rod and disc. The plunger moves along the axis of the flow of the working medium through the saddle and thereby changes the flow area.

Where are motorized metal valves used:

• At individual and centralized stations for the distribution of heat carrier, hot water, ventilation and air conditioning.
• At thermal power plants and other energy facilities.
• On the technological highways of various industrial buildings, in particular, the oil and chemical industries.

Two-way motorized control valves are designed to restrict the flow of the transported medium while maintaining the required mixing ratio. They have two outlets for connection to the pipeline by means of flanges. They can also perform the function of a regulator of differential pressure and power of indirect action. As you can see, in addition to the corrective option, they are also endowed with the properties of shut-off valves, which cannot be said about three-way valves.

They are intended for the separation and mixing of substances transported by the highway, but they cannot limit the flow rate, while maintaining the mixing ratio. Three-way valve with electric drive is characterized by the presence of 3 branch pipes for flange connection. If products of the first type are more often used on centralized pipelines, then these units are more in demand in autonomous systems. There are still electric four-way control valves, but they are used extremely rarely. Such fittings allow mixing the flow according to the double bypass algorithm.

Operating modes of two-way equipment:

• Full coverage of the working environment.
• Maintaining the nominal flow rate of the transported substance.
• Intermediate - flow restriction on 10-50% from a given consumption.

If there are no additional settings, then the nominal flow rate of the medium is taken as the standard operating mode.

Despite the fact that in the vast majority of cases flanged models are used, there are also valves that are mounted in the pipeline by welding. It is used in highways transporting aggressive compounds, where tightness requirements are as strict as possible. The advantages of such products are compact dimensions and low weight. However, they can only be used in steel structures.

The composition of the electric drive:

• Electric motor with gearbox.
• Control block.
• Feedback and control signal sensors.

Commands to the engine are transmitted by the control system. The unit also regulates the operation parameters and supplies power to all structural elements of the valve.
