Description Size 8 Component series B Maximum operating pressure 500 bar Maximum flow 5 l/min Features Direct operated directional seat valve with solenoid actuation, tight on both sides Mounting cavity R/T-8A Blocked port tight in a leak-free form Reliable switching even after longer periods of standstill Wet-pin DC solenoids Solenoid coil can be rotated Product description General The 2/2 directional seat valves are direct operated, pressure-compensated screw-in cartridge valves. They basically comprises 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 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 / 500 bar (see Technical data). Attention! The flow is only admissible in the direction of arrow (see symbols)! With version “U” (operating pressure 500 bar), the main port ➀ must be connected to the 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 manner. The manual override allows the switching of the valve without solenoid energization. It is available in concealed version "N9" (5) or in screwable version "N11" (6) (see ordering codes).
