The externally piloted globe valve consists of a pneumatically operated Envelope Dimensions [mm] (see datasheet for details)
piston actuator and a 2-way angle valve body. Sealing integrity is guar-
anteed by the proven self adjusting gland. These maintenance-free and Dimensions shown for
robust valves can be retrofitted with a comprehensive range of accesso- 2101 for exact 2012
ries for position indication, stroke limitation or manual override.
