Frequently Asked Questions
Q: What is the main difference between the KE02 and KE05 models?
A: The main difference is the cracking (opening) pressure. The KE02 model has a 0.2 bar opening pressure, while the KE05 models have a 0.5 bar opening pressure, making the KE02 more efficient in low-pressure-drop applications.
Q: What flow rate and pressure can this valve handle?
A: It can handle a flow rate of 300 l/min and a maximum working pressure of 350 bar.
Q: Why would I choose a KE02 valve over a standard model?
A: Choose the KE02 if your hydraulic circuit is highly sensitive to pressure losses or requires maximum energy efficiency, as its 0.2 bar opening pressure minimizes unwanted pressure drop.
Q: What types of seals and fluids is it compatible with?
A: It uses NBR seals and is compatible with HL, HLP, and HFC hydraulic fluids.
Q: In what type of system is this valve particularly beneficial?
A: It is especially beneficial in high-flow systems where maintaining low system pressure drop is critical, such as in energy-efficient mobile hydraulics or large industrial circuits with long pipe runs.
