Sequence Valve Features

Model No. L7-0412-00 Assembly 100% stainless steel valve. Construction resists corrosion which can cause other styles to "misfire". Direct acting poppet style, ad­just­able, cartridge type con­struc­tion. Cartridge may be installed directly into your manifold. Set Pressure adjustment range: 2.0 MPa (20 bar) to 6.2 MPa (62 bar). Two-port design eliminates need for third fluid line to drain bypass flow (internal leakage) back to system res­er­voir. True sequence design allows full system pressure downstream of valve after opening Up to 10 MPa (100 bar) system pressure. Recommended Filtration: 25 Micron (NOM) / 40 Micron (ABS) minimum. We recommend a 1 - 1.5 MPa (10 -15 bar) spread between pressures when using multiple valves. 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 down stream. 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.

Note: Maximum system flowrate is 11.4 l/m. Excess flow voids warranty.

Manifold Mount

• Valve is 100% stainless steel construction and resists the corrosion which can cause other styles to "misfire."
• Direct acting poppet style, adjustable cartridge type construction.
• The cartridge may be installed directly into your manifold.
• Two-port design eliminates need for third fluid line to drain bypass flow (internal leakage) back to system reservoir.
• True sequence design allows full system pressure downstream of valve after opening.
• Recommended Filtration: 25 Micron (Nom)/40 Micron (ABS)(minimum).

All dimensions are in inches.

For proper sealing, mating surface must be flat within .08, with a maximum surface roughness of 1.6 Ra μm.
