Metric Accessory Valves
- Vektek accessory valve designs are specifically intended for use in hydraulic clamping systems.
- Steel components, hardened operating parts and flow rates matched to the demands of workholding.
- Vektek valves will deliver safe, reliable long-life.
- Vektek accessory valves prevent system damage and erratic operation frequently experienced through the use of valves designed for general industrial applications.
- Sequence Valves' two-port design eliminates the need for a third fluid line to drain bypass flow (internal leakage) back to system reservoir.

Precision In-port Flow Control Valve
The new In-port Flow control can be used on all standard manifold mounted Swing Clamps and on both high and low pressure Link Clamps. These tiny units may be especially useful for flexible part applications where components must clamp at nearly the same time.
- Time clamp on sensitive fixtures
- Reverse free flow check valve
- Smallest high pressure flow control on the market
- Prevent component cam damage from unexpected or accidental surges in flow rate>
- Use with single or double acting Swing Clamps
- Flow control requires use of manifold mount ports

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.
