Function and configuration

·2/2 Directional Poppet valves

General:

2/2 directional poppet valves are direct operated, pressure compensated cartridge valves. They are comprised of screw-in section (1), solenoid (4) as well as closing element (3) and compression 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 350/500 bar.

Attention!

Flow is only admissible in the direction of the arrow (see symbols)!

With version "U" (operating pressure 500 bar), main port ① must be connected with pump connection P!

With symbol "P", the closing element (3) is pressed onto the seat by the solenoid (4), 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" (5) or in screwable version "N11" (6).
