The manual balancing valve STVA(E) is optimized for use in heating- and cooling systems.
STVA (E) is a ANSI 125# flanged valve.
STVA (E) are sized with nomogram, handwheel or online Applications on smartphones or on our webside.
STVA (E) shall be dimensioned with 50-80 % of maximum flow for the design flow.
Minumum recommended differential pressure is 2 kPa (0,29 psi)
Max closing pressure
Cast iron: DN 65-150, Electrolytic zinc plating
DN 200-300, Electrolytic zinc plating
ANSI 125# flanged
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 balacing valve.
On STVA (E) DN 65-150 an Allen key of 6 mm is used on the inner spindle to lock the setting.
On STVA (E) DN 200-300 the key is enclosed.
When the hand wheel is locked the valve cannot be opened to a larger value but it can be closed for maintenance of the connected circuit.
NOTE! For the STV range, it is only suitable to use neutral fluids
