Transcription

1 VGx-xx-xx Externally Threaded Control all Valves PN25 (DN15 TO DN32) PPLICTION The VG2 2-Way and VG3 3-Way Control all Valves control hot and chilled water with glycol solutions up to 50% according to VDI2035 in heating, ventilating, and air conditioning (HVC) systems to provide two-position or modulating functions. Features Sizes from DN15 to DN32 with external (male) SPP (G) connections 1" to 2". Equal percentage flow characteristic. Compatible MVN Rotary Valve ctuators: 2-position, floating, modulating, non-spring return. Removable manual operating handle to control valve during installation or in the event of power failure. ctuator can be mounted on the valve in any of four orientations. Wide range of kvs choices from 0.25 to 25. Nickel-chrome plated brass ball. Valve installs in a globe valve "T" pattern, no extra elbows or piping required. Mixing or diverting control for 3-way valves. Leakage rate, air bubble-tight (according to EN ). Specifications SPECIFICTION DT Valve type Control all Valve ody pattern 2-way (VG2-xx-xx), 3-way (VG3-xx-xx) Nominal pressure rating PN25 Media temperature range C ( F) Connection type Male SPP, threaded connections, flat sealing Controlled fluid Chilled or hot water according to VDI2035 with up to 50% Glycol.

5 VGx-xx-xx EXT. THREDED CONTROL LL VLVES PN25 (DN15 TO DN32) SPECIFICTION DT Mounting When installing the valve care must be taken that the flow direction is correct (see section "Typical Operation" below). The valve must not be mounted with the stem pointing downward. The valve is supplied complete with mounting instructions. The water quality must meet VDI 2035 requirements. NOTE: Mount the actuator by hand, only. Do not use a tool, as this could result in damage Typical Operation ll types of valves should be mounted in the return flow. If the Dp-values exceed 300 kpa, attention should be paid to the development of noise. Fig. 6.
