Transcription

1 VGx-xx-xx Externally Threaded Control all Valves PN25 ( TO DN50) 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 to DN50 with external (male) SPP (G) connections 2-1/4" to 2-3/4". Equal percentage flow characteristic. Suitable actuators: M6061/M7061; N05xx and S05xx (requiring /U Linkage Kit ordered separately) 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 25 to 63. 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 ).

5 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. 7.
