General Description
The DN5 is a metal to metal seated hydraulic control valve. The stainless steel seat
design ensures a leak tight shut o. The valve design incorporates a balanced internal
piloting system to enable the low powered solenoid coil to switch the valve at high
pressures.
The DN5 Pilot and Mainstage use cartridge insert technology which simplies
replacement and considerably reduces “downtime” costs. Features of the DN5 are an
‘O’ Ring interface that enables it to be tted with a subplate, or manifold mounted for
use in local control panels for actuators and wellhead control applications.
By removing just 4 bolts the valve can be dismounted without disturbing pipework
and possibly contaminating the hydraulic system. Blanking or ushing plates can also
be supplied.
