Function of a 2 Way Control Valve

• Regulates flow in one direction (unlike some
  multi-directional valves).
• Opens or closes based on external signals
  (pressure sensors, control systems).
• Actuators (pneumatic, electric, hydraulic) adjust
  valve position based on signal.

Diverse Types of 2 Way Control Valves
Globe Valve Widely used, precise flow control
across a wide range.
Ball Valve Simple operation, quick on/off
control.
Butterfly Valve Compact, easy to operate, less
precise control than globe valves.
Diaphragm Valve Handles corrosive/abrasive
fluids, good flow control.

Widespread Applications of 2 Way Control Valves

• HVAC Systems Regulate water flow for temperature
  control.
• Process Industries Precise flow control in
  reactors, pipelines, etc.
• Power Generation Manage water/steam flow for
  efficient power generation.
• Water Treatment Control chemical dosing, filter
  backwashing, flow rates.

5
Selecting the Right 2 Way Control Valve

• Fluid Type Material compatibility (corrosion,
  abrasion, temperature).
• Pressure Flow Rate Valve rating must match
  system requirements.
• Controllability Precise flow control (globe
  valve) vs. quick on/off (ball valve).

6
Conclusion

• Understanding functions, types, and applications
  empowers engineers.
• Selecting the right 2 way control valve ensures
  efficient, safe, and well-regulated operations.
