Overview
Flow Control Valves are precision-engineered devices designed to regulate and maintain desired flow rates of liquids or gases within a process. By varying the valve opening, these units ensure stable flow, pressure balance and system protection.
Available in manual, pneumatic, hydraulic or electric actuation, Flow Control Valves are vital components in process automation, energy efficiency and fluid handling systems across industries.
Key Features:
- Accurate flow regulation and throttling capability.
- On–off or modulating control options for flexible operation.
- Actuation types: manual, pneumatic, hydraulic or electric.
- Flow characteristics: linear, equal percentage or quick opening.
- Rugged and compact design suitable for demanding service conditions.
- Optional accessories: positioners, limit switches, solenoids and transmitters.
- Available in multiple configurations — globe, ball, butterfly, diaphragm or angle body.
Technical Specifications (Typical):
- Size Range: DN15 – DN600 (½” – 24”).
- Body Material: Carbon Steel, Stainless Steel, Bronze, Ductile Iron or Alloy Steel.
- Pressure Rating: PN10 – PN100 / ANSI 150 – 600.
- Temperature Range: –40°C to +400°C.
- Connection Type: Flanged / Threaded / Socket Weld / Wafer.
- Actuation Options: Manual / Pneumatic / Electric / Hydraulic.
- Signal Input: 3–15 psi / 4–20 mA / 0–10 V / Digital Protocols.
- Accessories: Positioner, Limit Switch, Feedback Transmitter, Solenoid Valve.
Operation Principle:
Flow Control Valves operate by adjusting the internal flow passage through actuator or operator control. This adjustment changes the flow area, allowing precise control of the fluid rate — maintaining desired process parameters despite pressure or demand variations.
Advantages:
- Precise and stable flow control for critical applications.
- Improves energy efficiency and system reliability.
- Suitable for a wide range of fluids and pressures.
- High repeatability and long operational life.
- Easy integration with process automation and control systems.
