Valve Module Combinations

Valve Module Combinations - ROEMHELD C 2.960

• Max. operating pressure 500 bar

Advantages:

• Reduced tubing for hydraulic fixtures
• Simulation of the clamping sequence possible in advance
• Reduced surface of attack for dirt and swarf at the fixture
• Less contamination in the fixture due to integrated line filters
• Reduced input flow rate due to existing flow control valves possible
• Required space for hydraulic control can already be considered during fixture design

Description:

The valve module combination consists of an input module and up to three series modules (for linkage of further modules please contact HYQUIP). In the input module the following hydraulic function elements are integrated:

• Flow control valve with connected line filter for both inputs to reduce the flow rate and to filter the fluid
• Pilot-controlled check valve to protect the clamping circuit in the case of pressure drop e.g. due to line break
• Pressure reducing valve to reduce the pressure for the first control function at the fixture
• Two miniature measuring connections to connect a pressure gauge for pressure adjustment

The series modules are directly linked to the input module. Thereby further clamping functions can be realised. The modules are equipped with the following hydraulic function elements:

• Sequence valve to realise one or several switching sequences (connected in series in the linked arrangement)
• Pressure reducing valve to reduce the pressure in the corresponding switching sequence
• Miniature measuring connection to connect a pressure gauge for pressure adjustment

In the base plates of the modules additional channels are provided which can be used as hydraulic / pneumatic channels or for the routing of electric lines. If permanent visual pressure monitoring is required, pressure gauges can be retrofitted

Application:

The valve module combination is a valve unit composed of individual modules. It is used to control complex hydraulic clamping fixtures. In order to fix safely workpieces in clamping fixtures, functions as positioning, clamping and supporting have to be effected in a determined sequence. In some applications it is required to realise the individual functions with reduced clamping pressures in order to guarantee optimum workpiece clamping. For this purpose sequence valves and pressure reducing valves are integrated in the hydraulic clamping circuit. Therefore considerably longer lines are required for tubing as well as for drilled channels. Due to the use of valve module combination the required line length is considerably reduced, since all required control and pressure valves are directly arranged at the unit.
