  Commanded retention valves  
  Modular assembly. Models 12 and 25. Sizes: CETOP 3 NG 6 and CETOP 5 NG 10.  
 
 
Commanded retention valves with modular assembly can be either simple or double. These valves prevent the fluid from flowing in a certain sense, unless there is a piloting pressure on the opposite channel so that there is a free backward movement. Their main purpose is to block an actuator in one or both channels, according to the valve applied, either simple or double.
They are supplied in three different assemble options as shown in the picture and with three different free flow pressures in each of the three models. They are manufactured in two different sizes: CETOP 3/ NG 6 and CETOP 5 / NG 10 for different flow volumes. The shape of the tops demonstrate the position of the retained channel, be it one of them or both.

 
 
- The following are the different model for each size:
RHC-M-12-#-RA one retained channel (A) CETOP 3 NG 6
RHC-M-12-#-RB one retained channel (B) CETOP 3 NG 6
RHC-M-12-#-RR two retained channels (A y B) CETOP 3 NG 6
RHC-M-25-#-RA one retained channel (A) CETOP 5 NG 10
RHC-M-25-#-RB one retained channel (B) CETOP 5 NG 10
RHC-M-25-#- RR two retained channels (A y B) CETOP 5 NG10
- Modular assembly system suitable to combine hydraulic systems.
- Three opening pressures for free passage in each model.
- Suitable to operate with up to 40 and 80 l/min and pressures up to 320 kg/cm² respectively.
