Frequently Asked Questions
Q1: Can this valve be used with water-based hydraulic fluids?
A: Yes, when equipped with compatible seals such as FKM or PTFE, it can handle water-glycol and other water-based fluids. Please specify your fluid type when ordering.
Q2: What is the typical lead time for custom bore plunger valves?
A: Standard customization takes 15-20 working days. Urgent orders may be expedited upon request.
Q3: Do you provide technical drawings for integration?
A: Yes, we provide 2D and 3D CAD drawings for your design team to verify fitment before production.
Q4: How do I determine the correct bore size for my press?
A: Our engineering team can assist based on your required flow rate and pressure. Generally, larger bores provide higher flow but require more actuation force.
Q5: What is the maximum stroke length available?
A: Stroke length is customizable; typical range is 20-300 mm. Longer strokes may require special design considerations.
Q6: Is there a minimum order quantity (MOQ)?
A: No MOQ for standard sizes. For fully custom designs, MOQ may apply depending on complexity.
Q7: How do you ensure valve quality?
A: Each valve undergoes pressure testing, leakage testing, and dimensional inspection per ISO9001 procedures.
Q8: Can this valve be used in high-cycle applications?
A: Absolutely. The hardened plunger and bore surface are designed for millions of cycles with minimal wear.
