DETAILS
The robust metal yoke allows ideal and simple mounting of mechanical or inductive limit switches. The fork can be removed from one side. This facilitates access to mechanical parts.
A mechanically retained round bead seal creates a bubble-tight closure at the edge of the gate.
A unique transverse seal, consisting of a transverse sealing profile and sealing compound, makes the body bubble-proof towards the atmosphere.
With its optimized port geometry, accumulated media is pushed out of the port guide and released into the hole by increased flow.
The cross seal can be repacked at any time and under full pressure using the side seal screws.
The Weyotine add-on cutting pack can be used to cut long fiber media, preventing jams and blockages.
