XPS10.3301 Sequence Valve

The XPS10 series valve is a pressure control valve that automatically controls the sequence of actuator operations using system pressure changes. It functions as a "pressure switch" in hydraulic systems—when the inlet pressure reaches the set value, the valve opens, allowing pressure oil to flow to the secondary circuit, enabling multiple actuators to operate automatically in a predetermined sequence.

Features

Sequence Control: Enables automatic operation of multiple actuators in predetermined sequence, simplifying hydraulic control systems
Normally Closed Structure: Inlet and outlet are normally closed, opens when set pressure is reached
Multiple Control Types: Direct-acting and pilot-operated options available for different flow and pressure requirements
Check Valve Option: Parallel check valve creates a sequence valve with free reverse flow capability
Drain Port Design: Requires separate tank line to relieve spring chamber pressure and maintain setting accuracy
Balanced Piston Design: High-pressure models feature balanced piston design, insensitive to outlet backpressure for stable operation

Operating Principle

Sequence valves are typically normally closed. When inlet pressure is below the set value, the inlet and outlet are blocked; when inlet pressure reaches the spring set value, the spool opens, connecting inlet and outlet, allowing pressure oil to flow to the secondary circuit. When used as a counterbalance valve, it prevents vertical loads from falling due to gravity.
Typical Applications
- Clamping-Drilling Circuits: Clamp workpiece first, drill feeds when set pressure is reached
- Multi-Cylinder Sequential Operation: Achieve predetermined sequence of multiple hydraulic cylinders
- Counterbalance Circuits: Prevent overspeed descent of vertical loads (models with check valve)
- Accumulator Charging Systems: Automatically switch charging status when pressure is reached
- Unloading Valve Function: Externally piloted sequence valve with outlet to tank can serve as unloading valve

Selection Note

The drain port of sequence valves must be connected separately back to the tank. Control type (internal/external pilot), pressure range, and flow must match system requirements. Contact us for selection assistance.
