 Hydraulic Open Die Forging Press Machine With Multi-grade Pressure Relief Valve

Hydraulic Open Die Forging Press Machine

Features:

* It used special multi-grade pressure relief valve that can eliminate the decompress impaction at the great

 flow rate for improving the speed of pressure relieving. And it also provides the technical guarantee for fast 

  forging.

* The automatic upgrading of forging pressure greatly raised the production efficiency

* It has established the connection on linkage between the press and the manipulator.

*It has reliable measurement of fire-protection

* Self-diagnosis of fault

* Hydraulic pumps are from Rexroth

* Siemens PLC
