Burkert 19059 (Type 0330) is a direct-acting, media-separated pivoted armature valve. It is configured as a 3/2-way variant (Circuit Function C - normally closed) and can be used as a distributor or mixing valve. The solenoid coils are moulded with a chemically resistant epoxy. Since the coil system is separated from the medium by a diaphragm, the valve is especially suitable for critical media. The 19059 features a brass body, NBR seal, and a G 1/4 port connection.

Note on Dimensions

For metal bodies, the minimum thread length at the middle connection is 7.5 mm. Screw-in depth of G 1/4 connection threads: When using pipe fittings, select variants with G 1/8, as the screw-in depth with G 1/4 is not sufficient.
