Function and configuration
·2/2 Directional Poppet valves
General:
The 2/2-way poppet valves are direct operated, pressure balanced
cartridge valves. They are comprised of a cartridge valve (4) with
valve seat (1), solenoid (5), as well as a closing element (3) and
pressure spring (2)
Function:
The initial position of the valve (normally open "P" or normally
closed "N") is determined by the position of the closing element
(3) and the arrangement of the compression spring (2). Due to the
structural design, the 2/2 directional poppet valves are always
pressure compensated in relation to the actuating forces. The main
ports ① and ② can be loaded with an operating pressure of
350bar/500bar (see Technical Data).
Attention!
Flow is only permitted in the direction of arrow (see symbols)!
With version "U" (operating pressure 500 bar) as well as with
version "R...-17", main port ① must be connected with pump
connection P!
Valves with version "R...-17" are flow-optimized and thus achieve a
higher pressure differential.
With symbol "P", the closing element (3) is pressed onto the seat
by the solenoid (5), with symbol "N" by the compression spring (2).
The flow is blocked in a leak-free form.
The manual override allows for the switching of the valve without
solenoid energization. It is available in concealed version "N9"
(6) or in screwable version "N11" (7).
·3/2 Directional Poppet valves
General:
3/2 directional poppet valves are direct operated, pressure
compensated cartridge valves. They ARE comprised of a screw-in
section (4) with valve seat (1), solenoid (5), as well as closing
element (3) and compression spring (2).
Function:
The initial position of the valve (normally open "U" or normally
closed "C" ) is determined by the position of the closing element
(3) and the arrangement of the compression spring (2).Due to the
structural design, the 3/2 directional poppet valves are always
pressure-compensated in relation to the actuating forces. The main
ports ① and ② can be loaded with an operating pressures of up to
350 bar/500 bar (see Technical Data) and are blocked in a leak-free
form in the respective end position. During switching, the main
ports are briefly connected (negative overlap).
Attention!
The flow is only permitted in the direction of arrow (see symbols)!
With version "U" (operating pressure 500 bar) as well as with
version "R...-17", main port ① must be connected with pump
connection P! Valves with version "R...-17" are flow-optimized and
thus achieve a higher switching power.
The manual override allows for the switching of the valve without
solenoid energization. It is available in concealed option "N9" (6)
or in screwable version "N11" (7). It is available in concealed
version "N9" (6) or in screwable option "N11" (7).
