Rotary valve couplings

 

Rotary valve coupling
for single-acting clamping elements,
8 stations

 

Rotary valve coupling
for double-acting clamping elements,
8 stations, triggered separetely

Description

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). Only hoses should be used for the pipe connection between the torque brace and the rotary piston.

At an operating pressure of about 200 bar and above, it is recommended that a hydraulic accumulator with a storage-safety device be fitted between the check valve and connector level A (permanent pressure area). This accumulator is for the purpose of compensating for minor fluid loss through leakage, when the machine is at rest in the loading and unloading station. You are recommended to use only directional valves to control the rotary valve coupling.
