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 up­stream of the valve have moved into position and pressure begins to increase, the in­creas­ing pressure overcomes the spring force holding the valve closed, forcing the poppet off its seat al­low­ing fluid flow through the valve. After downstream devices have positioned and clamped, and pressure has increased to equal upstream pressure, the entire system pressure rises to the maximum level 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 valve to return to the power unit reservoir.

Model No. 47-0440-02  and 47-0440-03 Assemblies Model No. 47-0440-00 and 47-0440-01 Cartridges Only 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. Pressure adjustment range is: 52 bar (5.2 MPa) to 350 bar (35 MPa) and 20 bar (2.0 MPa) to 62 bar (6.2 MPa). 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)

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.

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.
