Control Valve

Control Valve Manufacturer & Supplier in India

Allied Valves India manufactures and supplies control valves for industrial automation applications across India. Our pneumatic and automated control valves are used to regulate flow, pressure, and temperature in process systems where stable control is critical.

Pneumatic Control Valve Manufacturer in India

As a control valve manufacturer, our focus stays on supplying valves that help maintain stable and predictable process conditions. Unlike isolation valves that operate only in open or close positions, control valves are designed for continuous modulation, adjusting flow based on incoming control signals.

Our manufacturing capabilities focus on robust and accurate designs:

  • Pneumatic Diaphragm Control Valves: These are the industry standard for reliable flow control. These valves use a flexible diaphragm actuator that responds to changes in air pressure, allowing the valve stem to move smoothly without sudden jumps.
  • 3-Way Control Valves (Mixing & Diverting): We also manufacture 3-way pneumatic diaphragm control valves for applications where flow needs to be mixed or diverted.

    • Mixing Duty: Combines two inlet flows into one outlet (ideal for temperature control).
    • Diverting Duty: Splits one inlet flow into two outlets (ideal for bypass or distribution systems).
  • Actuation Technology: These valves can be supplied with I/P converters and valve positioners so they can work with standard 4–20 mA control signals used in PLC and DCS systems.

These control valves are manufactured using materials such as Cast Steel (WCB) and Stainless Steel (SS 316), selected based on pressure, temperature, and fluid characteristics.

Industrial Control Valve Suppliers in India

Allied Valves India is a trusted Control Valve supplier in India, supporting automation needs in Textiles, Pharmaceuticals, and Petrochemicals.

Why do instrumentation engineers work with Allied Valves for control valve requirements?

  • Precise Calibration: Each control valve is calibrated in our facility so the valve stroke closely follows the input signal, helping reduce hysteresis and dead band issues.
  • Severe Service Readiness: Our control valves are designed to handle high pressure drops and elevated temperatures while reducing the risk of cavitation and flashing in demanding applications.
  • Spare Parts Availability: We maintain a stock of diaphragms, springs, and packing kits to ensure your control loops have minimum downtime during maintenance.
  • Custom Flow Characteristics: We can provide valve trims with Linear, Equal Percentage, or Quick Opening characteristics depending on your process requirement.

Frequently Asked Questions

Q. What is the function of a Pneumatic Control Valve?

A Pneumatic Control Valve regulates fluid process variables—such as flow rate, pressure, or temperature—by varying the size of the flow passage. It operates using compressed air acting on a diaphragm or piston actuator, which moves the valve plug to a specific position based on a control signal.

Q. What is the difference between Mixing and Diverting Valves?

In a Mixing Valve (3-Way), two different fluid streams enter the valve and are mixed into a single exit stream; this is common in water tempering applications. In a Diverting Valve, one fluid stream enters and is split or diverted into two separate outlets. Allied Valves manufactures both types.

Q. Do you supply accessories for Control Valves?

Yes. As a comprehensive automation valve supplier, we can outfit our control valves with Electro-Pneumatic Positioners, Air Filter Regulators, and Limit Switches to provide a complete control valve assembly that is easier to install and commission at site.
