With our commitment to quality, combined with year of exposure to industry, we are first choice for all your flow control need.   

Control valve is an important component of any process system which control the flow of fluid, gas, or steam in a pipeline. Control valve plays important role in keeping the process variable such as pressure, temperature and flow rate at the desired level. 

  

Main Components of a Control Valve 

  1. Valve Body: It is the primary enclosure that houses the internal parts and connects with the system pipeline. 

  1. Actuator: An apparatus which respond to control signal, adjusting the position of the valve to regulate the flow. The actuator can be pneumatic, electric, or hydraulic. 

  1. Control Valve Trim: Includes the plug, seat, and stem, which govern the flow. 

  1. Positioner: A device that can be fitted to ensure that the valve will respond as per the commands of the control system. 

  1. Packing: Stipulates fluid leak prevention from the valve when operating, thereby maintaining safety and system integrity. 

Working Mechanism 

The operational mechanism of a control valve is such that the actuator is signaled by the control system to change the valve opening. Based on pressure, temperature, or flow rate, the actuator moves the valve plug within or out of the valve seat, hence changing the fluid flow. This real-time adjustment keeps the valve at the required operating conditions and enables the system to perform at optimum efficiency. 

 

Advantage:

  • Accurate Flow Control: Control valve offer quick and accurate flow control essential for system efficiency and stability. 

  • Automation: With control system integration, control valve facilitate automatic control of process variable, minimizing manual interference. 

  • Energy Efficiency: Accurate flow control prevent wastage of energy, leading to efficient and sustainable process. 

  • Reliability: Control valve are engineered to withstand high pressure, harsh temperature and corrosive media ensuring sustained performance. 

  • Safety: Through controlling pressure and flow rate that are wanted, control valve prevent hazardous overpressure and unsafe operation. 

Industries 

  1. Oil and Gas: For pipeline, refinery, and petrochemical plant flow regulation. 

  1. Chemical Processing: In flow regulation of various chemicals and ensuring the proper mixture of substances. 

  1. Power Generation: For steam, gas, and water flow regulation to turbines, boilers, and cooling systems. 

  1. Water Treatment: For regulation of water flow and chemical dosing in treatment plants.
