Honeywell Kombi-8F Series Flanged Pressure Independent Integrated Balancing Control Valve is a new generation product used for precise temperature control of terminal air-conditioning equipment in the HVAC system and an integrated product of linear temperature control, pressure independent and electric regulating.
Honeywell Kombi-8F Series can carry out the precise linear temperature control according to the thermal output features of the terminal equipment. Additionally, such control is pressure independent i.e., in the process of control, the flow of the terminal equipment is only affected by the temperature change in the air-conditioned area, instead of being affected by the pressure fluctuation of the water system. It can dynamically balance the pressure change of the system so as to ensure the flow of terminal equipment will not interfere with each other.
Honeywell Kombi-8F Series can also output variable differential pressure characteristics value signal to the system for the variable differential pressure control of the variable flow water system so that the air-conditioning water system can always operate in the most energy-saving mode.
Honeywell Kombi-8F Series Flanged Pressure Independent Integrated Balancing Control Valve is a kind of pressure independent, high-accuracy linear temperature-control two-way control valve, with the dimensions of DN65-DN150, which is composed of the ML-SBE Series super electric actuator component and flanged control valve. the super electric actuator component includes super electric actuator, pre-sensor, sampling straight pipe, special exhaust valve, three-way ball valve, three-way pipe and bypass hose etc.
Honeywell Kombi-8T Series Threaded Pressure Independent Integrated Balancing Control Valve is a new generation product used for precise temperature control of terminal air-conditioning equipment in the HVAC system and an integrated product of linear temperature control, pressure independent and electric regulating.

Honeywell Kombi-8T Series Threaded Pressure Independent Integrated Balancing Control Valve is a kind of pressure independent high-accuracy linear temperature-control two-way control valve, with the dimensions of DN25-DN50, which is composed of the ML-SBE Series super electric actuator component and Threaded control valve. The super electric actuator component includes super electric actuator pre-sensor, special exhaust valve, three-way ball valve, three-way pipe and bypass hose etc.
It is suitable for use in variable and constant flow systems. They may be used as constant flow limiter in constant flow systems (without an actuator) or as a Pressure Independent Control Valve
in variable flow systems.
As a new type of product that controls the temperature of FCU in heating, ventilation and air-conditioning systems, honeywell dynamic balancing control valves integrate the functions of dynamic balancing and electrical switches in one body with great features including compact structure, high accuracy and stable operation.
Honeywell Kombi-9 is designed for precise temperature control of terminal air-conditioning equipment in the HVAC system. It can maintain the flow regardless of variations in system differential pressure. With the valve position feedback the Building Automation System can always operate in the most energy-saving mode.
The V5003F Kombi-VX is an automatic balancing valve. It is designed for balancing of heating and cooling systems by providing a constant flow rate even under changing pressure conditions. The flow rate can be externally adjusted via pre-settings.
The paddle type SPDT WFS series are designed to provide excellent performance where accuracy, reliability, and rugged construction are required used in liquid flow lines carrying water or any fluid neither harmful to brass and prosphor bronze nor classified as a hazardous fluids.
They can be wired to close one circuit and open a second circuit when liquid flow either exceeds or drops below the adjusted flow rate. The WFS series are recommended for liquid pressure and temperature
as mentioned below and must not be used on lines carrying liquids below 0 /C.
These series may be used on liquids with high salt or chlorine content but is not for use in hazardous atmospheres. They may be also used outdoors but must be protected from weather or splashing water.
Where an operating control failure would result in personal injury and/or loss of property, it is the responsibility of user to add safety devices that protect against, or supervisory systems that warn of control failure.
Besides the basic controls, TF428 series featuring CPH (Cycle Per Hour) better maintains the room temperature to the setpoint and Random Start-up Function would help to maintain power grid stability.
Besides the basic controls, TF228WN featuring CPH(Cycle Per Hour) better maintains the room temperature to the set-point and memorized time off function can automatically turn off the thermostat to save energy.
These single seated valves are used for modulating control of hot or chilled water or steam in heating, ventilating and air conditioning systems and can be operated by electric linear actuators as ML6421, ML7421, or by pneumatic actuators MP953.
These single seated valves are used for modulating control of hot / chilled water or steam in heating, ventilating and air conditioning systems. The valves can be operated by linear actuators ML6421B and M7L421B or by pneumatic actuators MP953.
The P7620C ceramic cell differential pressure transmitters and transducers have been designed for most industrial pressure measurement applications at high quality performance and precision accuracy requirement including fluids and gases. The ceramic cell and metallic wetted parts can be compatible with majority of aggressive process fluids. The output signal of the sensing bridge is in converted to be a standardized current or voltage signal through surface mount technology circuit board. This high
level signal output with very low noise system is packaged in a rugged stainless steel housing to resist the harsh and extreme environment conditions.
They protect systems against malfunction and corrosion damage resulting from the ingress of foreign bodies such as welding beads, sealing materials, metal cuttings and rust etc. This extends the life of the downstream system and prevents early failure.
Honeywell VN Series 2-position on/off valves are used in domestic and small commercial heating and cooling applications to control the flow of hot and/or cold water. They consist of an actuator and valve assembly
They can be used to control individual fan coil, radiator, space heater or convector applications. Depending on the model selected they can be controlled by a SPST or SPDT controller such as a room thermostat, aquastat or flow switch.
The T775 electronic stand-alone controllers are the next generation of commercial and agricultural controls capable of remote sensing of temperature and providing switched and/or proportional outputs to various types of loads.
IMPORTANT
The T775 is an operating control, not a limit or safety control. If used in applications requiring safety or limit controls, a separate safety or limit control device is required. Read more in PDF
The H600A Humidity Controller has spdt switching to operate humidification equipment on RH fall or dehumidification equipment on RH rise (or for mildew control with air conditioning systems). All models have a locking cover, the setting knob actis as cover removal tool.Read more in PDF
CS42XX, CS75XX, CS81XX Spring Return Direct Coupled Actuators (DCA) are used within heating, ventilating and air conditioning (HVAC) systems They can drive a variety of quarter-turn, final control elements requiring spring return fail-safe operation. Read more in PDF
The hydronic balance is a significant requirement for the efficient operation of a hydronic heating or cooling installation. In an unbalanced system under or over provision of hot water to individual radiators or circuits can occur. Apart from the
correct selection of radiator valves, regulation of individual circuits is also necessary and in some cases, such as in DIN 18 380, VOB part C, is required by national standards. This requirement is met with the shutoff and balancing valve
Kombi-2-plus. The Kombi-2-plus for the return has the functions shutoff, pre-setting, regulation (with diaphragm unit, accessory), draining and filling (draining adapter, accessory).
