  Simple retention valves  
  Modular assembly. Models 12 and 25. Sizes: CETOP 3 NG 6 and CETOP 5 NG 10.  
 
 
Modular retention valves are used when it is necessary to close the pressure or create pressure in one of the channels of the fluid, while allowing free flow in the opposite channel.
Said valves are fitted with a float, which is charged in advance and ensures an unrestricted flow, with a minimum charge loss.
These valves are available in two different sizes: CETOP 3 NG 6 and CETOP 5 NG 10. They are also manufactured for the P and T channels in only one sense, and on the A and B channels in both senses. One valve can have one or two retentions inserted on different channels.

 
 
- Modular assembly – Suitable to link hydraulic systems together.
- The available versions are the following:
EP= Retention on the P channel with free flow towards the valve.
SB= Retention on the B channel with free flow towards the actuator.
SA= Retention on the A channel with free flow towards the actuator.
EA= Retention on the A channel with flow retention towards the actuator.
EB= Retention on the B channel with flow retention towards the actuator.
ST= Retention on the T channel with free flow towards the deposit.
-Three different opening pressures in free flow mode for each model.
-Suitable to operate with flow volumes up to 40 and 80 l/min and pressures up to 320 kg/cm², respectively.
