TA-COMPACT-P– with NPT and SWT connections

Pressure independent balancing and control valve (PIBCV)

The pressure independent balancing and control valve TA-COMPACT-P ensures optimum performance over a long life. Adjustable maximum flow enables design flow and eliminates over flows for accurate hydronic control. The TA-COMPACT-P together with our balancing instruments enables advanced measuring and diagnostics.

Features and Benefits

Precise hydronic balancing
Smoothly adjustable setting of max. flow prevents over flow through terminal unit.

Installations without limits
Slim and compact shape simplifies installation, one side access to all functions simplifies operation.

Full control of the system
Exact flow measuring and unique diagnostic functions for ultimate energy savings and highly reliable system.

High reliability
AMETAL® and stainless steel guarantees high corrosion resistance and reduces the risk of leakage.

Applications

Heating and cooling systems.

Functions

Control

Differential pressure control

Isolation (for use during system maintenance – see "Leakage rate")

Measuring (ΔH, t, q)

Pre-setting (max. flow)

Pressure class [PN]

PN 16 (230 psi)

Differential pressure (ΔpV)

Max. differential pressure (ΔpVmax ): 58 psi

Min. differential pressure (ΔpVmin ):

Size 3/8” - 3/4”: 2.2 psi

Size 1” - 1 1/4”: 3.3 psi

(Valid for position 10, fully open. Other positions will require lower differential pressure, check with the software HySelect.)

ΔpVmax = The maximum allowed pressure drop over the valve, to fulfill all stated performances.

ΔpVmin = The minimum recommended pressure drop over the valve, for proper differential pressure control.

Flow range

The flow (qmax ) can be set within the range:

3/8”: 0.095 - 0.53 gpm

1/2” LF: 0.19 - 1.08 gpm

1/2”: 0.39 - 2.07 gpm

3/4”: 0.92 - 5.06 gpm

1”: 1.63 - 9.46 gpm

1 1/4”: 3.52 - 16.3 gpm

qmax = gpm at each setting and fully open valve plug.

LF = Low flow

Temperature

Max. working temperature: 194°F

Min. working temperature: 14°F

Media

Water or neutral fluids, water-glycol mixtures (0-57%).

Characteristics

Linear, best suited for on/off control

Leakage rate

Leakage flow ≤ 0.01% of max. q, max (max. setting) and correct flow direction. (Class IV according to EN 60534-4).

Lift

0.157 in

Actuators

See separate technical documentation on EMO T and TA-TRI.
