Special Hydraulic System Bolts & Valve Parts For Machining Components
Product Overview
Our high-performance bolts and precision valve components are specifically engineered for hydraulic systems in mechanical processing equipment, ensuring leak-proof sealing, high-pressure resistance, and long-term durability.
Key Features
✔ Material Excellence – Made from hardened alloy steel/stainless steel for corrosion resistance and high tensile strength.
✔ Precision Machining – Tight tolerances (ISO/DIN standards) for seamless integration into hydraulic systems.
✔ Pressure & Vibration Resistance – Designed to withstand extreme hydraulic pressures (up to XXX bar/psi) and dynamic loads.
✔ Customization Options – Available in various sizes, thread types, and sealing configurations (O-ring, tapered, flange).
✔ Wide Applications – Ideal for CNC machines, presses, injection molding systems, and other heavy-duty machining equipment.

FAQ
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.
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.
Bolts: Up to 10,000 PSI (700 bar).
Valves: Rated for 6,000 PSI (420 bar) (higher pressures available upon request).
Absolutely. We offer OEM/ODM services for non-standard sizes, materials, coatings, or sealing types (e.g., O-ring vs. metal-to-metal).
Use our pre-tested bolts with integrated O-ring grooves and valves with PTFE/metal seals. Proper torque settings and thread lubrication are critical.
ISO 9001, RoHS, and REACH compliance. Valves may include CE or API 6D (specify if needed).
Custom: 4–6 weeks (depends on complexity).
