Generator coupling 500-4

Rotary valve couplings transmit hydraulic fluid to revolving tables. The structure is designed as a rotary slide valve, which permits several hydraulic devices to be supplied simultaneously with hydraulic fluid under pressure, and independently of that, a loading and unloading station to clamped or unclamped by means of distributing valves. Special features: axial and radial connections in the piston single-acting or double-acting designed with up to 10 stations 1 or 2 stations for loading/unloading for seperately or simultaneously triggering standard rotary valve couplings and special designs available Important operating instruction: The rotary valve coupling must only be operated with hydraulic fluid. All levels must be connected to the pressure generator in order to guarantee lubrication of the seals. Operation must only be carried out with the screw connections fitted. Rotary valve couplings should only be used for phased operation. Mounting instruction: The rotary valve coupling must only be operated with hydraulic fluid. All levels must be connected to the pressure generator in order to guarantee lubrication of the seals. Operation must only be carried out with the screw connections fitted. Rotary valve couplings should only be used for phased operation. The Rotary Valve Coupling must be fitted in such a way that no bending moment is exerted on either the stationary or the rotating component. It has proven effective to bolt the rotating housing with the connectors to the clamping devices and merely to secure the standing piston against twisting (prevent initiation of bearing forces).
