Frequently Asked Questions
What valve types are available for the drilling mud pump fluid end?
We offer valve types 5#, 6#, and 7# designed for drilling mud pump fluid ends. Each type is manufactured to API 7K standards and is directly interchangeable with OEM part numbers from major brands such as BOMCO, HONGHUA, RG, RONGSHENG, EMSCO, and LSNOV.
What insert materials are available, and how do they affect service life?
Insert materials include Polyurethane (PU), Nitrile Rubber (NBR), Hydrogenated Nitrile (HNBR), and Fluorocarbon (FKM). The choice of material directly impacts service life, which ranges from 150 to 350+ hours. HNBR and FKM are recommended for more aggressive or high-temperature drilling conditions, while PU and NBR are suitable for standard applications.
Are these valve bodies compatible with oil-based and corrosive drilling fluids?
Yes. These valve bodies are designed to operate with water-based, oil-based, and highly corrosive drilling fluids commonly used in oilfield drilling operations. The 20CrMnTi alloy steel body provides excellent strength and corrosion resistance across a wide range of drilling environments.
What quality certifications and third-party inspections are available?
Our valve bodies conform to API 7K standards. Third-party witness and inspection reports are available from recognized international bodies including Bureau Veritas (BV), CCS, ABS, and SJS. These certifications ensure product quality and compliance for demanding oilfield applications.
What working pressure and temperature range do these valve bodies support?
The valve bodies support working pressures of 5000 PSI (35MPa) and 7500 PSI (51.7MPa), with a temperature rating of -20°C to 120°C. This makes them suitable for a wide range of onshore and offshore drilling conditions.
How can I find the correct part number for my specific pump model?
For BOMCO pump models, please refer to the OEM compatible part number table above. For valves used in HONGHUA, RG, RONGSHENG, EMSCO, and LSNOV pumps, please contact our sales team directly. We can provide detailed part number references and technical support to ensure you receive the correct replacement valve body.
