We can help our customer to select proper equipment suitable specifications and maintain required parameters to handle and satisfy the process demand.

There are manual operated, pneumatic – hydraulic and electric operated control valves with ON/OFF style or modulating control style with positioner – controlled with earlier pressure range 3 to 15 psi (0.2 to 1.0 bar) and more commonly now with electric signals  4 to 20 mA for Industry and  0 to 10 volt for HVAC System. Electric control now often includes a “smart” communication signal superimposed on the 4-20mA control current, such that the health and verification of valve position can be signaled back to the controller. The HART, Fieldbus foundation and Profibus are the most common protocols

An automatic control valve consists of three main parts, in which each part exists in several type and designs:

  • Valve actuator – which moves the valve’s modulating elements, such as Ball or Butterfly.
  • Valve positioner – which ensures the valve has reached desired degree of opening. This overcomes the problem of friction and wear.
  • Valve body – in which the modulating element a plug, globe, ball or butterfly is contained.

The common control valves are:

  • Sliding Stem type – Globe Valves, Angle body valve & Angle Seat Piston Valve.
  • Rotary Stem Type – Ball and Butterfly Valve
  • Other Type – Pinch Valve and Diaphragm Valve

The fundamental function of Valve Positioner to deliver pressurized air to the valve actuator such that the position of the valve stem correspondence to the set point.

Agility Engineering-Tech Co., Ltd. focus on ultimate goal of customers satisfaction, product quality, safety, effectiveness, some customized applications like heating jackets adaptations, featuring various materials of construction, pressure ranges, end connections and following all standards to make easy for customers to select our products.

The main contents are:
