Direct Acting Sequence Valves
The sequence valve with primary pressure cut-off is mainly used to feed two cylinders in sequence: when a certain setting is reached, the valve opens and provides flow to a second actuator. The check valve enables the free passage of the flow in the opposite direction. It is suitable for systems in which the pressure on the secondary actuator is limited, given the fact that the pressures are added up.

Application Scheme
USE AND OPERATION:
Sequence valve is used to feed 2 cylinders in sequence: it provides flow to the secondary circuit when a primary circuit function has been completed reaching the pressure setting.
Return flow is free. It’s ideal for circuits with low pressure on the secondary actuator as the pressures add to.
MATERIALS AND FEATURES:
Body: zinc-plated steel
Internal parts: hardened and ground steel
Seals: BUNA N standard
Poppet type: minor leakage
APPLICATIONS:
For use with 2 actuators, follow the mounting instructions indicated in the scheme.
For different uses, mount the valve keeping into consideration that, when the valve reaches the setting pressure, the flow goes from V towards C, whilst flow is free from C to V.
ON REQUEST
• different setting range (see the table)
• other settings available (CODE/T: please specify the desired setting)
