2방 제어 밸브 (2-WAY CONTROL VALVE) SJXS 220

[개요 (Description)] The valve which controls two positions or the proportion of cold/hot water, steam and air. The body and the seat are manufactured in bronze. The valve stem stainless steel, and valve plug, STS. The stuffing box prevents leakage by using an O-ring. The feature curve of the valve is equal percentage or linear type. The elevation of stem by the actuator close the valve.

[기술사양 (Technical Data)] . 허용압력(Operating pressure) : JIS 16Kgf/㎠ . 동작온도(Operating temp.) : -15~180℃에서 DIN 4747/DIN 3158 . 밸브흐름 특성(Valve curve) : Equal percentage or Linear . 누수율(Leakage rate) : ≤0.01% of Kvs value ClassⅣ (ANSI B 16.104) . Connection ; PT Screwed [적용 (Application)] This model can be employed in a wide range of applications such as cooling, air handng, steam and hot water systems for use with electric actuators. Hot water : Max 130℃ Chilled water : -15℃ Max. in closed circuit Only water with following additives. - Hydrazing, Phosphate, for frost protection - Glycol, max. 50%, for frost protection. ★ Upon customers requets, Body material of SCPH2, SCS13 are available.
