Compact Manifold Mount Sequence Valve

Accessory Valves

• Control the timing of fixture devices.
• Specialized construction resists corrosion which can cause other styles to misfire.
• Direct acting poppet style construction.
• Cartridge is installed directly into your manifold.
• True sequence design allows full system pressure downstream of valve after opening.
• Recommended Filtration: 25 Micron (NOM) / 40 Micron (ABS) (minimum).

OPERATION: The VektorFlo® sequence valve operates as a pressure sensitive, normally closed element in a clamping system. When fluid first enters the system at low pressure, the valve is closed, blocking the flow of fluid to devices downstream. After devices in the other branches of the system have moved into position, the pressure begins to increase. The increasing pressure overcomes the spring force holding the valve closed, forcing the poppet off its seat and allowing fluid flow through the valve. After all devices have positioned and clamped, the downstream pressure increases to equal upstream pressure. Pressure throughout the system will increase to the maximum setting on the hydraulic power supply. When unclamping, as pressure falls, force from the adjustment spring pushes the poppet back onto its seat. Fluid trapped in the downstream circuit flows back through the check seat to return to the power unit reservoir.
