FAQ

1. What materials are used in your hydraulic bolts and valve parts?

• Bolts: High-strength alloy steel (Grade 10.9/12.9), stainless steel (A2/A4), or corrosion-resistant coatings (Dacromet/Zinc).

• Valves: Carbon steel, stainless steel, or brass, with optional hard chrome plating for wear resistance.

2. Are these components compatible with standard hydraulic systems?

• Yes. Our bolts comply with DIN/ISO/ANSI standards, and valves meet ISO 4401, SAE J518, or DIN 24340. Custom threads (BSPP/NPT/SAE) are available.

3. What pressure ratings do your products support?

• Bolts: Up to 10,000 PSI (700 bar).

• Valves: Rated for 6,000 PSI (420 bar) (higher pressures available upon request).

4. Can I request custom sizes or configurations?

• Absolutely. We offer OEM/ODM services for non-standard sizes, materials, coatings, or sealing types (e.g., O-ring vs. metal-to-metal).

5. How do I ensure leak-proof performance?

• Use our pre-tested bolts with integrated O-ring grooves and valves with PTFE/metal seals. Proper torque settings and thread lubrication are critical.

6. What certifications do your products have?

• ISO 9001, RoHS, and REACH compliance. Valves may include CE or API 6D (specify if needed).

7. What’s the lead time for standard vs. custom orders?

• Custom: 4–6 weeks (depends on complexity).
