Accessory Valves

Sequence Valves

Manifold Mount Sequence Valve  20% narrower than standard sequence valve.  Valve is 100% stainless steel construction and resists the corrosion which can cause other styles to "misfire."  The valve is the same one used in the larger block.  Direct acting poppet style, adjustable cartridge type construction.  The cartridge may be installed directly into your manifold.  Pressure adjustment ranges are: 52 bar (5.2 MPa) to 350 bar (3.5 MPa) and 20 bar (2.0 MPa) to 62 bar (6.2 MPa).  True sequence design allows full system pressure downstream of valve after opening. n Recommended Filtration: 25 Micron (NOM) / 40 Micron (ABS) (min.)

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 A

For proper sealing, the mating surface must be flat within 0.08 mm with a maximum surface roughness of 1.6 µm R a 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.

NOTE: Maximum system flow rate is 5.7 l/min. for all VektorFlo® special function valves unless otherwise noted. When using multiple sequence valves. For pressure set range 20 to 62 bar a 7 bar spread between pressures is recommended. For pressure set range 52 to 350 bar a 35 bar spread between pressures is recommended.
