Valves & Thermostats

Two- or four-pipe heating and/or cooling systems are characterized by changing conditions due to valves opening and closing depending on the need for heating or cooling. This continuously causes flow and differential pressure changes. PIBCV helps attain these solutions with ease.

Valves and Valve Actuators

Honeywell commercial HVAC valves control steam, water and water with glycol media in heating and cooling applications. Available in 2-way and 3-way configurations and sizes from 1/2" to 20", precision valves ensure a correct fit for economic operation and long equipment life. Specify a Honeywell valve and put a proven performer on every job.


By adding an actuator, the valves function as flow-limited control valves, automatically balancing the system and providing the best possible indoor comfort and energy efficiency. The commissioning of the system is a lot easier; all valves only need to be set to the design flow before the actuators are mounted. With mechanical gear type actuators, Danfoss PIBCV solutions maintains high accuracy Danfoss offers a broad range of pressure-independent balancing and control valves and matching actuators distributed by Al Tayer Engineering.

Stable room temperature: Eliminating the overflow situations at partial load conditions has a significant effect on the stability of the room temperature

Improved indoor comfort: With the stable room temperature, the indoor comfort increases. Required temperatures are accurately met, increasing the productivity of office employees or benefiting the experience of hotel guests.

Energy savings: The perfectly balanced system, under all conditions, increases the energy efficiency and leads to savings on energy costs.

Reduced maintenance costs: As the pressure-independent valves ensure perfect working conditions, the actuators mounted on them require fewer movements to keep the temperature stable. This increases the lifetime value of the actuators and reduces the maintenance costs.
