Three Way Control Valve - MNC Valves India

THREE WAY CONTROL VALVE

Industrial Mixing & Diverting Control Valves | WCB / Stainless Steel

MNC Valves is a Three Way Control Valve Manufacturer in India supplying industrial control valves designed for flow mixing and diverting applications in automated process systems.

Three way control valves are used where two fluid streams need to be mixed or where a single flow needs to be diverted into two separate outlets.

These valves are commonly used in temperature control systems, heat exchangers, and industrial process automation.

Typical applications include:

  • Chemical processing plants
  • HVAC systems
  • Heat exchanger systems
  • Power plants
  • Water treatment plants

MANUFACTURING STANDARDS

Manufactured according to international engineering standards:

  • ASME B16.34 – Pressure Temperature Ratings
  • ASME B16.5 – Flanged End Connections
  • API 598 – Testing & Inspection
  • IEC 60534 – Control Valve Performance
  • ISO 5211 – Actuator Mounting Interface

PRODUCT DESIGN OVERVIEW

Three way control valves consist of a valve body with three ports allowing controlled mixing or diverting of process fluids.

The actuator moves the valve plug to regulate flow paths between the ports.

Typical valve assembly includes:

  • Valve body with three ports
  • Trim assembly (plug, seat, stem)
  • Bonnet assembly
  • Actuator system
  • Positioner (optional)

This design enables controlled distribution or mixing of fluid streams.

VALVE CONFIGURATION

Mixing Type Three Way Control Valve

In mixing configuration two inlet flows combine into a single outlet.

Common applications: Heat exchanger temperature control, Process fluid blending, Industrial mixing systems.

Diverting Type Three Way Control Valve

In diverting configuration one inlet flow is diverted into two separate outlets.

Common applications: Flow distribution systems, Cooling systems, Industrial process control lines.

SIZE RANGE

  • DN 15 mm to DN 300 mm
  • Larger sizes available on request

Pressure ratings depend on valve design and process conditions.

MATERIALS OF CONSTRUCTION

Body Materials Trim Materials Seat Materials
WCB – Carbon Steel, SS304, SS316 Stainless Steel trim, Hardened options available PTFE, Metal seat (depending on application)

ACTUATION OPTIONS

Three way control valves can be supplied with:

Pneumatic Actuator

  • Most widely used in industrial process control
  • Fast response operation
  • Suitable for continuous modulation

Electric Actuator (Motorized)

  • Used where compressed air supply is not available
  • Suitable for remote automation systems

Manual Override

Optional manual operation for maintenance or emergency situations.

OPERATING PRINCIPLE

The actuator adjusts the valve plug position to regulate flow between the three ports. Depending on valve configuration, the control valve performs either:

  • Mixing of two inlet flows into one outlet or
  • Diverting of one inlet flow into two outlets.

This enables precise control of process temperature, pressure, and flow distribution.

DESIGN FEATURES

  • Accurate flow distribution control
  • Smooth throttling capability
  • Compatible with automation systems
  • Reliable sealing performance
  • Positioner compatible design
  • Robust industrial construction

INDUSTRIES SERVED

Three way control valves are widely used in:

  • Chemical processing plants
  • HVAC temperature control systems
  • Heat exchanger systems
  • Power plants
  • Water treatment plants
