Control Valve

Control Valve

Control globe valves are engineered for precise flow regulation in critical process systems. These valves offer linear or equal percentage flow characteristics and can be fitted with various actuators and positioners for automated operation. They can control the flow rate, pressure, temperature, or level of the fluid by opening or closing partially or fully in response to a signal from the controller.

Control valves are essential for optimizing the performance, efficiency, and safety.

Typical Applications Are

Oil & Gas Power Generation Petrochemicals HVAC Water Treatment

Construction Details

Body

The body of a flow control valve serves as its central structure, housing and securing all other integral components. Body with top entry trim and bolted bonnet facilitates easy access to all internal parts for online inspection, maintenance and trim replacement.

Bonnet

Bonnets are manufactured from the same material as the Body. It utilizes a bolted flange type stuffing box construction. The packing box design is such that all types of packing are interchangeable.

Trim

The trim is located within the valve and encompasses critical components such as the stem, seat, and disc. The interface between the seat and disc plays a pivotal role in determining valve performance. Trims with top bush guided plugs are available with simple construction for stable operation.

Disk & Seat

The disk is a crucial element of the flow control valve responsible for allowing or restricting fluid flow.

Stem

Stems are responsible for connecting the actuator and the disc, securely holding the disc in position.

Actuator

Control valve actuators are diaphragm actuators with pre-compressed multi spring construction. Control valve actuators may be operated manually, pneumatically or by an Electric Motor.

Handwheel

Valve handwheels are a common type of valve actuator used for manual control, enabling users to adjust the valve's opening and closing.

Valve Packing

Valve packing serves as a sealing system, employing deformable materials in solid form or split rings held within a packing box. This sealing system prevents leakage between the stem and bonnet, ensuring the integrity of the valve's operation.
