Middleeast valve is one of the greatest Triple Duty Valve Suppliers in UAE.  It is a specialized type of control valve used in HVAC (Heating, Ventilation, and Air Conditioning) systems and plumbing systems to perform three important functions within a single valve assembly.

The operation of a valve involves adjusting its position to control the flow of fluid and perform the desired function. To balance the system, the valve’s flow control mechanism is adjusted to control the flow rate through the valve. To shut off the flow completely, the valve handle or actuator is turned to the closed position. This seals off the flow path, preventing any fluid from passing through.

To enable bypass, the valve’s flow control mechanism is set to allow a controlled amount of fluid to flow through the bypass path while the main circuit is partially or fully closed. This helps in maintaining system stability during low-demand conditions.


  • Flow Control: Triple duty valves have an adjustable flow control mechanism to balance the flow of fluid within the system.
  • Shut-off Capability: They can fully shut off the flow of fluid when needed.
  • Bypass Control: The valve allows for the controlled bypass of fluid to prevent issues like low flow rates or freezing.
  • Pressure/Temperature Gauges: Some triple duty valves come with pressure and temperature gauges to monitor system conditions.
  • Durability: They are typically built to withstand the harsh conditions of HVAC and plumbing systems.
