Information

 up to 8 bar (116 psi) and flow rates of up to 350 l/min (92.4 gpm). It is available as 3/2- or 2/2-way valve in normally closed or normally open position. On request it can also be designed as a 3/2-way valve to work as junction or mixer. Optionally this valve is available with manual operation and/or switch position indicator.

The default case material of the valve is PPSU. On special request it can also be made with other plastics suitable for injection molding. The seals are available either in NBR, FKM or EPDM (depending on the application). Externally either a flange or a push-in connection for 4 or 6 mm hoses with outer calibration can be selected. Depending on the application, even combinations of flange and push-in connections are possible – for example a 2/2-way in-line version with push-in connection. In combination with a connector according to industry standard EN 60529 the new valves conform to IP65 protection rating. The new fluid isolation solenoid valve from Kendrion in compact design is available for 12 V DC or 24 V DC operation. On request, other input voltages are available as well.
