E-CAGA 3:1 pilot ratio, vented counterbalance valve - atmospherically referenced

SYMBOL

DESCRIPTION

Three-way port, poppet valve, control spring main chamber internal oil return, threaded cartridge type. 

OPERATION

The one-way function: allow the oil flow from 2 to 1, when the pressure of 1 is less than the spring set value, the cut-off 1 flow to 2; Overflow function: when the pressure of 1 is greater than the spring set value, 1 to 2 for overflow function. Liquid control throttling function: when the port 3 has control pressure, control 3 pressure can be changed from 1 to 2, the size of the opening, from which the throttling function is achieved.  

FEATURES

* The maximum set pressure is 1.3 times the pressure generated by the maximum load.

* The back pressure of the vent 2 should be within the set pressure. 

* The reset pressure should be greater than 85% of the set pressure. 

* The load pressure is 210 bar when setting pressure at 280 bar for CA*A, CA*K. 

* The load pressure is 320 bar when setting pressure at 420 bar for CA*G, CA*L.
