What is the difference between your accessory valves and others I already use?
Vektek accessory valves are sized for the normal flows and conditions present in hydraulic clamping systems. They are not intended for use in general industrial equipment as they are specifically intended for clamping. Maximum intended flow rate on any Vektek accessory valve is 1.5 gpm (unless otherwise noted). Excessive flows may cause damage or erratic behavior.
What is the function of a pressure relief valve (PRV)?
Pressure relief valves are intended to guard against excess pressure. When a circuit builds beyond the setting of a pressure relief valve, it opens and pressure is relieved from the system. If a relief valve is set below the pressure switch adjustment of a pump, the pump will kick on and off frequently. Incorrect adjustment of a pressure relief valve can cause expensive damage to your pump.
Explain why you don't want me to put a group of sequence valves in series.
When a group of sequence valves is put in sequence they have to work harder than if they are fed parallel from a single main feed line. Vektek sequence valves modulate as fluid passes through them, trying to maintain upstream pressure. The interruption of fluid flow through one valve will adversely effect the modulation of the next valve in line, resulting in erratic performance. You may put as many sequence valves in parallel as you wish. We recommend approximately 500 psi difference in their settings for ease of installation.
