Industrial valves are essential across sectors such as manufacturing, utilities and energy, where accurate flow control is critical. While designs vary by application, most industrial valves rely on the same core components. Understanding these shared parts helps engineers and maintenance teams diagnose issues, plan servicing and specify equipment with greater confidence.
Valve Body
The valve body forms the main pressure boundary and houses all internal parts while connecting to the pipeline. In industrial valves, body materials are chosen based on pressure, temperature and media type, making this component fundamental to safety and durability.
Bonnet
The bonnet sits above the valve body and encloses the stem and packing. It helps contain pressure while allowing access for maintenance. A well-sealed bonnet supports reliability without compromising serviceability in industrial valves.
Actuator
The actuator provides the force needed to open or close the valve. It may be manual, pneumatic, hydraulic or electric depending on control requirements. Actuators enable precise operation and support automation in complex systems. This improves responsiveness, safety, reliability across industrial environments.
Stem
The stem transfers movement from the actuator to the internal closure element. Proper stem design reduces wear, supports smooth motion and helps maintain accurate positioning over time.
Obturator
The obturator directly controls flow and may take the form of a ball, disc or wedge. It opens to allow flow and closes against the seat to stop it.
Seat
The seat creates the sealing surface that prevents leakage when the valve is closed. Seat materials are selected to suit operating conditions and process media.
