V5050A,B FLANGED LINEAR VALVE PN16 AND PN25/40

Transcription

1 V55A,B FLANGED LINEAR VALVE PN16 AND PN25/4 GENERAL These threeport mixing valves are used for modulating control of hot/chilled water or steam in heating, ventilation, and air conditioning systems and can be operated by electric linear s ML642/ML6425, ML742/ML7425, and ML6421/ML7421 or by pneumatic MP953. SPECIFICATION DATA FEATURES Cast iron body with flanged end connections Low seat leakage rate Metaltometal seating for long life span Selfadjusting packing Accurate positioning to ensure stateoftheart temperature control Easy mounting of directcoupled electric and pneumatic s Constant total flow throughout entire plug travel SPECIFICATIONS Action Stem up to close port AAB Nominal pressure rating PN16, PN25/4 Flow characteristic linear for ports AAB and BAB Rangeability 5:1 Leakage rate.1 % of k VS port AAB.1 % of k VS port BAB Stroke 2 mm mm...15 Valve body End connections Flanged per ISO 752 Material Cast iron (GG25) PN16 Cast steel (GSC25) PN25/4 Dimensions See Fig. 1.
