Sequence valves are designed to control the operating order of actuators in a hydraulic system by opening or allowing flow only after a preset pressure is reached. They ensure correct sequencing of movements, stable system operation, and protect pumps, pipelines, and actuators from overloads.
Such valves are widely used in industrial equipment, mobile and heavy machinery, presses, machine tools, lifting equipment, construction, and agricultural machinery, where a defined order of operations based on pressure is required.
Sequence valves are available in subplate-mounted versions for installation on standard mounting plates, as well as in cartridge versions for direct integration into hydraulic manifolds. This allows flexible system design, compact layouts, reduced pressure losses, and easy maintenance.
Those valves are rated for operating pressures of up to 420 bar and flow rates of up to 480 l/min, ensuring reliable, durable, and safe performance under demanding operating conditions.

Argo-Hytos sequence valves control the order of operations in hydraulic systems by opening at a preset pressure. They ensure proper actuator sequencing and are rated for pressures up to 420 bar and flow rates up to 40 l/min.

Duplomatic sequence valves control the order of operations in hydraulic systems by opening at a preset pressure. They ensure proper actuator sequencing and are rated for pressures up to 350 bar and flow rates up to 150 l/min.

SUN Hydraulics sequence valves control the order of operations in hydraulic systems by opening at a preset pressure. They ensure proper actuator sequencing and are rated for pressures up to 350 bar and flow rates up to 480 l/min.
