Control valves

Toensure the accuracy of the process parameters different techniques of control valves management are used, often with special drives or actuators. The adjustment process is performed by industrial microcontrollers via sensor command by means of electrical, pneumatic, hydraulic or electromagnetic actuators for control valves. Special classes and certification of control valves we supply allows their use for mission-critical tasks on rigs and platforms, refineries and other hazardous production facilities.

  • Pneumatically operated valves are designed for more specialized applications, such as: Media with high dirt content, media with high viscosity, high ambient temperatures, large flow quantities, damp environments and where there is a risk of explosion.

  • These valves are generally of large size and are used for different applications such as Pump discharge etc. Motor Operated Valves are often called as On-Off valves as the motors serve the purpose of fully opening or fully closing valves in pipelines.

    Pressure-control valves are found in virtually every hydraulic system, and they assist in a variety of functions, from keeping system pressures safely below a desired upper limit to maintaining a set pressure in part of a circuit.

    Typical applications include water treatment, chemical, marine, petrochemical and general industry.

  • This valve is used on a liquid service, which opens proportionally as the increasing pressure overcomes the spring pressure.

    A flow control valve regulates the flow or pressure of a fluid. Flow Control valves normally respond to signals generated by independent devices such as flow meters or temperature gauges. Control valves are normally fitted with actuators and positioners.
