Product Q&A

Q:What is a control valve and how does it work?

control valve regulates fluid flow, pressure, or temperature by varying the flow passage size. It consists of a valve body, actuator (pneumatic/electric/hydraulic), and positioner. The control system sends a 4-20 mA signal to the positioner, which moves the actuator to adjust stem travel and modulate flow to match the process setpoint. Widely used in oil & gas, chemical, and power generation industries.

Q:What are the main types of control valves?

The main types are: Globe valves (precise throttling, high _P), Ball valves (on/off, low pressure drop), Butterfly valves (large diameter, low pressure), Angle valves (flashing/high-velocity service), and Cage/plug valves (severe service, noise & cavitation control). Selection depends on fluid type, required Cv, pressure differential, temperature, and leakage class.

Q:What is the difference between a pneumatic and an electric control valve?

pneumatic control valve uses compressed air (typically 3-15 psi) to drive the actuator - fast response, fail-safe by design, preferred in hazardous areas. An electric control valve uses a motor-driven actuator - no air supply needed, easier integration with digital control systems, and suitable for remote or outdoor installations. Choice depends on available utilities, response speed, and safety requirements.
