¢Â General The valve which controls two positions or the proportion of cold/hot water, steam and air, district heating. The body is manufactured in castiron and the valve stem, seat, valve plug are in stainless steel. The stuffing box prevents leakage via O-ring and Vition
¢Â Technical Data - Operating Pressure : JIS 20 Kgf/§² - Operating Temp : -25 ~ 200¡É - Valve curve : Equal percentage or linear - Leakage rate : ¡Â 0.01% of Kvs value Class IV
¢Â Application Hot water : max 180¡É Chilled water : -25¡É max. in closed circuit only water with following addit
- Hydrazine, Phosphate, for frost protection. - Glycol, max 50%, for frost protection. - Saturated steam, superheated steam 6bar, abs/max 180¡É
¢Â Specification
Pvmax in Kgf/§² = max. prem, pressure difference across the valve at which the drive can still safely.open and close the valve. Psmax in Kgf/§² = max. prem, pressure difference across the valve during malfunction at which the.drive can close the valve. |
