Product description
General
The 2/2 directional seat valves are direct operated, pressure-compensated screw-in cartridge valves. They basically consist 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 "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 seat valves are always pressure-compensated in relation to the actuating forces. The main ports ➀ and ➁ can be loaded with an operating pressure of 350 bar (see Technical data).
At 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 manner.
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) (see ordering codes).
The screwable manual override (7) is to be screwed back into the initial position after actuation.
