Hermetic slide valves of 150x150 to 600x600 (also available: 1000x1000) are product-tight in the leadthrough and pressure-tight to the outside (dependent on the valve size). They are equipped with an inside seal and with wear plates.
Sealing slide valves between DN 100 and DN 600, with flanges as defined in PN 10 DIN 2501 on both sides, are pressure-tight in the leadthrough and to the outside (dependent on the valve size) as a result of the prestressed seal located opposite the fully machined sealing plate that runs in eccentric pulleys.
Attention: The bulk materials must be technically dry, i.e. they must not cake, stick or plastify.
