Are all these accessories fully compatible with the SJ Petro ZJ40 seven bank valve lines (Z07060000012AA)?

Yes, all accessories are specially designed and produced for the SJ Petro ZJ40 seven bank valve lines (model: Z07060000012AA). Each part’s model and size strictly match the original equipment, ensuring perfect compatibility. They also comply with API 6D and EN 12516-1 standards, guaranteeing stable connection, tight sealing, and safe operation in harsh drilling environments.

2

How often should key wearing parts (hoses, bushings, sealing-related parts) be replaced to avoid valve line failure?

Under normal drilling conditions (8 hours a day, 5 days a week), hose assemblies should be replaced every 12 months, bushings and fittings every 10-12 months (depending on disassembly frequency), and washers every 6 months. If working in harsh environments (high dust, high temperature, frequent high-pressure operations), shorten the replacement cycle by 30% to prevent unexpected leakage or failure.

3

What should I do if the seven bank valve lines fail to operate smoothly or have abnormal noise?

First, stop the equipment immediately and cut off the hydraulic supply to avoid further damage. Then check three key points: 1. Whether the handle assembly is loose or worn (causing stuck operation); 2. Whether bushings/fittings are loose or blocked (causing uneven oil flow and noise); 3. Whether the hydraulic oil is contaminated or insufficient (causing poor lubrication). Tighten loose components, replace worn parts with matching models from this catalog, clean blocked components, and replace/top up hydraulic oil before resuming operation.
