Description
BG-300 type gate valves are widely used in fracturing operations in field and have gained recognitions from customers. The valves are designed to meet API 6A and API 16C specifications and have passed PR2F test. This valve has the characteristics of zero grease injection during fracturing, zero leakage, low operating torque and maintenance free.
Description
- Wave springs, set behind the seats
- Floating slab gate.
- Convertible between manual and hydraulic operation.
- Convertible from manual to hydraulic within 15min under pressure.
- Self-energizing stem packing.
- Tungsten carbide surface on the gate and seat.
Benefit
- Zero grease injection during frac jobs.
- Zero leakage during frac jobs.
- No sand enters into the cavity
- Reduce the working time between fracturing without grease injection.
- Reduce the labor intensity.
- Safer and more reliable.
- Reduce the grease entering the well to causing pollution.
- Weight reduced by over 25%.

Field Service
|
From June 29 to July 28, 2025, the BG-300 type gate valve was used in Xinjiang, and was successfully cycled (opened/closed) 49 times throughout the fracturing process. Valve Status by Well: Open during fracturing of Well 15 and Well 16. Closed during fracturing of Well 17. Fracturing Stages Completed: Well 16: 36 stages Well 15: 33 stages Well 17: 23 stages |

the need for grease injection. Proppant Specifications: Three sand size grades were used: 70-140 mesh, 30-50 mesh, and 40-70 mesh. Overall Site Pressure Range: 40 ~ 90 MPa Detailed On-Site Fracturing Parameters: Pressure: 73 ~ 80 MPa Flow Rate: 4 m³/min ~ 10.2 m³/min Proppant Volume: 10 m³ ~ 100 m³ Valve Teardown Inspection: No sand ingress was found in the valve's middle chamber. Virtually no grease loss was observed in the middle chamber. (This inspection confirms the valve's excellent sealing integrity and resistance to harsh downhole conditions.) |
