Control valves with electric and pneumatic actuators

What is a motorized control valve?

  In the modern world, automation and computerization of management processes is advancing by leaps and bounds. Do not stay away from technical progress and control systems for pipeline networks for various purposes.

The management of pipeline networks is, first of all, the control of the flows of the pumped medium: their volume-mass indicators (throughput), composition, temperature and pressure. Therefore, the main executive body of automation systems (computerization) of pipeline networks today is a control valve with a remotely controlled drive: electric, pneumatic (steam), hydraulic, and on other control principles. After all, actuated control valves of various designs are a type of pipeline shut-off and control valves, and are designed to solve the same problems in pipeline networks as manually controlled shut-off and control pipeline valves: gate valves, valve valves, taps and mixers - but already on the principles of remote ( remote) control.

Scope of application and tasks to be solved

  The scope of application of motorized control valves can be any modern industrial, economic (municipal) and even household pipeline network, in which it is justified and expedient to introduce automation processes or computerization of control of work processes and parameters. Practical tasks that can be accomplished with remotely operated motorized control valves:

  • saving on maintenance personnel, bringing the entire monitoring and control system of pipeline equipment to a single control post;
  • a dramatic reduction in the reaction time of the control action on the parameters of the working medium in the pipeline, which can be critically important in fast-flowing technological processes or emergency-hazardous systems;
  • time-programmed change of environment parameters; for example, variable supply of heat carrier to the heating system of a residential, office or industrial facility, depending on working or non-working hours;
  • automation of changing the parameters of the medium depending on the parameter external to the pipeline system; for example, changing the supply of heating medium to the heating system depending on the outside temperature (so-called weather-compensated heating control).

Typology of motorized control valves and their actuators (incomplete)

  Remotely operated motorized control valves are most commonly found in the following types:

  • two-way, with one shutter, one landing seat and two branch pipes (inlet and outlet), for locking, unlocking and regulating one medium flow.
  • three-way, (a) only the first channel is open; (b) only the second channel is open; (c) mixing different media from two inlets, or dividing one medium into two different circuits), with two valves, two seating seats, and three nozzles: two (one) inlets and one (two) outlets.

Three-way valves can be:

  • mixing, which organize the mixing of two different media, for example, cold and hot water, with automatic maintenance of the required temperature parameter at the outlet;
  • dividing, performing automated separation of the supplied medium flow into two separate circuits;
  • switching, producing switching of the supplied medium flow to different directions. They are used, for example, when it is necessary to alternately switch double-circuit heating boilers to the power supply of various heat exchange (heating) circuits.

Despite the relative diversity of the principles of a controlled drive of control valves, in industrial practice, the most common are:

  • Control valves with linear (analog) electric actuator: two- and three-position, for two-way and three-way valves, respectively. To computerize the management of pipeline networks, electric control valve actuators are equipped with electric actuated positioners. Electric actuated control valves are characterized by simplicity of design (based on electric induction magnets), organization of their connection and power supply, and in proper operating conditions - reliability and durability in operation. At the same time, the electric drive is critically dependent on the supply of electric current and is sensitive to high humidity conditions. Therefore, it often requires additional (expensive) measures to ensure the constancy and stability of power supply (electric storage capacities for emergency power supply, UPS), electrical protection for conditions of high humidity and continuous water cut (sealed enclosures, insulation, etc.).

  • Control valves with linear pneumatic actuator. To computerize the management of pipeline networks, pneumatic control valve actuators are equipped with pneumatic positioners. Pneumatic control valves are characterized by a slightly greater technical complexity (especially in installation) and less technical reliability in operation, but at the same time - complete independence from the presence or stability of the power supply. Therefore, they are successfully used for the conditions of emergency-hazardous systems and continuous technological processes, in which the continuity of the control effect on the parameters of working environments is critically important, or in conditions of high humidity, water content, explosion hazard in industrial premises.

  Design features of motorized control valves and their actuators

  Although actuated control valves are adapted to work in conjunction with remotely controlled actuators (electromagnetic, pneumatic (steam), hydraulic and others), they should be considered separately structurally. Very often these are completely independent units, united into a single executive body according to the principle of "designer", or large-node interface.

As a control valve can work with external drives of various types and designs, so the controlled drive can be installed on various valves, in a certain range of their overall and operating parameters. Therefore, in implementation, actuated valves can be purchased both assembled with a controlled actuator, and separately: only a control valve, or only a controlled valve actuator.

The actuated control valve itself (without a drive) by its design practically does not differ from a two-way or three-way valve with a manual drive of a valve or lever type, with the movement of the locking element parallel to the flow of the medium. Although there is also a variant of the design of a controlled butterfly valve, the so-called "butterfly" type. The only significant difference is that the valve stem is standardized for mating with typical controlled external actuators. The translational movement of the valve stem is communicated either by an electromagnet armature (electric drive) or by a movable diaphragm (pneumatic drive).

Depending on the thermodynamic (including the aggregate) state and the chemical composition (chemical activity) of the working medium, control valves can be made of various construction materials:

  • cast iron;
  • carbon steel;
  • high-alloy (stainless) steel;
  • aluminum and alloys;
  • copper alloys: brass, bronze;
  • titanium, and others.
