先导型 2位2通电磁方向控制座阀 – 双向流通

Wandfluh is expanding its range of poppet valves. The pilot operated 2/2 screw-in cartridge SVSPM33 of the size M33 x 2 in accordance with ISO 7789 as of new is also double sealing and capable of both directions of flow. It is available in versions, which are certified for areas subject to explosion hazard. All versions have been developed for volume flows of up to 120 l/min and pressures of up to 350 bar and fulfil the high demands with respect to an excellent sealing tightness. The slip-in coil principle with a pressure-tight armature tube ensures a simple maintenance.
In doing so, the slip-in coil - the electrical part of the valve - can be rotated and changed without the hydraulic system having to be opened.
The screw-in cartridges have been developed above all for the demanding modular construction in the stationary- and mobile fields. They are utilised for applications, in which the holding of loads, tensioning and clamping free of leakage oil are of decisive importance.
By means of the expansion with versions for areas subject to explosion hazard, the cartridges in addition are suitable for applications in the marine- and offshore fields as well as in the oil-, gas- and chemical industries.
