1 STV DN -0, Balancing valve High accuracy Easy to adjust Quick to commission Dimension: DN -0 Temperature: -0 C till + C Pressure class: PN 0 June 0 rev.

2 Description STV (M,F,G) DN -0 Application The manual balancing valve STV (M,F,G) is optimized for use in DHWC, heating- and cooling systems. Sizing 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 0-0 % of maximum flow for the design flow. Minumum recommended differential pressure is kpa (0, psi) Setting 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 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. Measuring The pressure test ports are opened by unscrewing the lids. Differential pressure can be measured using a balancing instrument. Draining STVM is equipped with a drain. The drain is opened with a screwdriver. Insulation STVF Is equipped with extra long PT ports. Mounting Mounting direction is clearly shown with an arrow on STV (M,F,G) STV has internal threads. STVG has external threads. June 0 rev.
