Jamesbury 6D15 Digester Capping Valve

The JAMESBURY 6D15 digester capping valves provide automatic opening and closing of batch digesters for chip fill. By automating this operation, complete computer control of a batch digester system is permitted. 

Available in 20" (DN 500) and 24" (DN 600) sizes, valves are normally full port ANSI class 150 design with an ANSI lass 300 flange on the digester end, and with a chip chute flange conforming to customer requirements on the fill end. 

Digester end flanges may also be cast and machined to meet the digester opening requirements. 

6D15 capping valves are furnished as complete operating assemblies that include a pneumatic actuator designed and manufactured specifically for large quarter-turn valve operation. 

An electromechanical interlock positively locks the valve in the closed position until signals indicate the cook is finished and the digester is completely depressurized. 

Enclosed limit switches provide interlock command signals and can remotely indicate valve and interlock positions.
