HYDRAULIC INSTALLATION

CONTROL VALVES

One of two types of control systems are used, depending upon the backhoe or
excavator used:

1. CONTROL SYSTEM USING THE EXCAVATOR AUXILIARY VALVE

This type of installation uses an existing excavator auxiliary valve (k7) to operate the

NPK Sheet Pile Driver (SD). Additional parts, such as mechanical linkage, hydraulic
pilot control valves (k11), etc., are furnished in the NPK HYDRAULIC INSTALLATION
KIT.

2. CONTROL SYSTEM USING THE NPK MULTIVALVE

For  excavators  not  equipped  with  an  auxiliary  or  spare  valve  section  as  part  of  the
control valve bank (k9), the NPK HYDRAULIC INSTALLATION KIT typically includes
a solenoid  operated, priority  valve  (k10) to operate the NPK  Sheet Pile Driver (SD).
The  NPK  MULTIVALVE  is  specifically  designed  for  the  operation  of  boom  mounted
attachments.
