DESCRIPTION
DENISON Vent Valves are electrically operated 3/2 way devices. They are
designed specially to unload pilot operated pressure control and seat valves.
Vent Valves direct the pilot oil to the power component to allow it’s designated
function at system pressure, or to the pilot oil return to allow unloading.
The DENISON design allows the VV01 to be sandwiched between the power com-
ponent or main body and the pilot section or cap of the valve that it is controlling.
Two different control spools are available for the functions ”power component
unloaded in normal position”and ”power component unloaded in switch position”.
The leakproof solenoids have only one type of tube cartridge and permit change of
coil and current without interfering the hydraulic circuit.
Optimal material quality and stringent manufacturing procedures ensure high
reliability under exacting operating conditions.
All the valve components are quality controlled based on international standards,
thus ensuring worldwide interchangeability of units.
Performance details for the vent valve are covered by the information on the follow-
ing pages. For full details of pilot operated pressure valves and 2-way seat valves
compatible with this vent valve, please refer to the corresponding bulletin.
A free of charge advisory service is available from your local DENISON office,
should you have special operational applications.
