Benefits

• 85 l/min nominal flow with fully internal pilot routing.
• No X and Y lines, connection is limited to P, T, A and B.
• Command value +/-10 V, on-board electronics, 24 VDC through a 7-pole connector (6 + PE).

• Built-in pressure reducing valve, NBR seals, UKCA conformity.

Application

The version fits machines with limited installation space in which every extra line is a nuisance, for example tool changers and clamping units. System pressure in port P also feeds the pilot stage. Low back pressure in the return line keeps control behaviour steady.
