Balancing valve STV with drain
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 website. 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 ISO threads. STV NPT has internal NPT threads. STVG has external ISO threads. STV soldering have soldering ends ASME standard.
