Description

Smart 2-way control valve with ultrasonic flow, temperature and power measurement

The IMI TA-Smart is a smart two-way control valve for heating and cooling terminals, air handling units and zones. An ultrasonic flow sensor and temperature sensors are built in, so the valve controls flow or power directly, shows flow, supply and return temperature, delta T and energy, and logs its data without separate meters. The valve characteristic is EQM, adjustable from EQM 0.25 to inverted EQM 0.25, which gives stable modulating control even at very low part-load flows. Hydronic systems in offices, hospitals, hotels and district energy substations use this type of valve to reduce pumping energy and keep delta T high.

Setup and diagnostics are done from a Bluetooth smart device with the HyTune app, and communication is by BACnet or Modbus, MQTT and analog signal. Cloud connection and delta T or return temperature limitation are optional. Change-over operation lets one valve serve heating and cooling.

Selection notes

Choose the size from the required maximum flow within the qsetmin to qnom range, and confirm that the differential pressure across the valve stays below 400 kPa. Below 2 C medium temperature the spindle must be protected from ice with vapor tight insulation. The user remains responsible for restricting physical and network access to the valve. A mechanical alternative is the IMI TA-Modulator pressure independent control valve; related valves are under Control Valves.

About brand

IMI TA is a name that HVAC engineers associate with hydronic balancing, the work of getting design flow to every terminal in a heating or cooling water system. The brand dates from 1897 and its focus is balancing and control valves. Seven Star LLC lists the IMI TA-COMPACT-P pressure independent balancing and control valve, DN 10 to DN 32, and supplies IMI TA valves in Oman on inquiry.

IMI TA-COMPACT-P valves

The TA-COMPACT-P in our listing is a pressure independent balancing and control valve for terminal units, made in sizes DN 10 to DN 32 and rated PN 16. One valve sets the maximum flow, holds it against pressure changes in the system and accepts an actuator for control. Body and insert are made of AMETAL, the manufacturer's dezincification-resistant alloy, and water-glycol mixtures up to 57 percent are permitted. Fan coil units and small air handling coils in chilled water systems are the usual place for a valve of this size.

Ordering IMI TA valves: what we need

Send the article number from the valve or the schedule, or the size, the thread type and the design flow rate for each valve. For actuators we need the control signal, the supply voltage and the cable length. Consultants on GCC building projects can send the full valve schedule for line-by-line checking against the manufacturer data.
