The manual balancing valve STV (M,F,G) is optimized for use in DHWC, heating- and cooling systems.
STV (M,F,G) are sized with nomogram, handwheel or online Applications on smartphones or on our webside.
STV (M,F,G) shall be dimensioned at 50-80 % of maximum flow for the design flow.
Minumum recommended differential pressure is 2 kPa (0,29 psi)
The pressure test ports are opened by unscrewing the lids.
Differential pressure can be measured using a balancing instrument.
STVM is equipped with a drain.
The drain is opened with a screw driver.
STVF Is equipped with extra long PT ports.
Mounting direction is clearly shown with an arrow on STV (M,F,G)
STV has internal threads.
STVG has external threads.
Max closing pressure
Dezincification resistance brass
The hand wheel has digital reading which shows whole turns and tenth of a turn.
The setting is shown in table format or can be calculated by using software on the website.
Any setting can be locked to avoid tampering with the setting of the balancing value.
An Allen key of 3 mm is used on the inner spindle to lock the setting.
When the setting is locked the valve cannot be opened to a larger value but it can be closed for maintenance of the connected circuit.
