1 NAF ProCap Capping valve DN00-70, ANSI -0 PN6, ANSI Class 0 Fk.(0)GB 0.7 Primary characteristics NAF ProCap, Capping valve for automated filling of wood chips to the batch digester in Pulp industries. The design provides a reliable and tight shuttoff valve with long life time, supplied as standard in stainless steel for pressure ratings PN 6 and ANSI Class 0 and in sizes DN00/, DN600/ and DN70/0. The valve has: an unique design using the eccentric hubs to load the seat and provide a tight shutoff an inlet neck that is drilled and tapped to accept direct mounting of the chip chute an outlet flange in std dimension or customized to meet existing digester flange a stainless steel ball segment with welded overlay of Alloy in the seat area Alloy seat has sealed stems with O-rings in PFM that prevent build up and results in an increased life time NAF Turnex high performance pneumatic actuators used for operation and eccentric hub locking device, cylinders in stainless steel with spring to lock the valve for safe operation CE-marked according to Pressure Equipment Directive (PED /68/EU) module H, category III. For module H, category IV contact NAF Application NAF ProCap is a batch digester capping valve for chips filling in a safe and time saving way.
