Product highlights:
1. By Pass Valve has Precision Shear System
- Calibrated shear pins require only "0.5~1.5MPa higher pump pressure than original" to rupture
- Pressure-tested to 15,000 psi with 200% safety margin
2. By Pass Valve Gas Formation Readiness*Gas Formation Readiness
- Mandatory installation "before drilling in a gas formation" per well control protocols
- Positioned at critical BHA points (near-bit/sub-assemblies)
3.By Pass Valve Fail-Safe Activation Sequence
- Four-step activation:
① Ball deployment via circulation ("put ball into retainer by pump")
② Pressure increase to shear pins ("fluid is closed... add pressure")
③ Sleeve displacement ("seal sleeve moves down")
④ Discharge hole opening ("pump pressure drops")
Overview of By Pass Valve：
The By-Pass Valve is a critical safety valve within the drilling tools ecosystem, engineered to restore circulation during well control emergencies. Installed near or directly on the drill bit before entering gas formations, this petroleum equipment provides a secondary flow path when the bit bore becomes blocked during kicks. As essential oil tools, it enables well killing operations by diverting fluid through discharge holes when conventional circulation fails, preventing catastrophic blowouts.
Advantages of By Pass Valve：
✅ Kicks-to-Control Transformation
> When well kick takes place and pump pressure is too high or blocked, activation restores circulation within minutes - converting
emergencies into controlled operations.
✅ Proactive Gas Zone Protection
> Pre-positioned per drilling plan to eliminate "bit nozzle blockage" scenarios in high-risk formations.
✅ Pressure-Relief Precision
> Shear pins calibrated to rupture at minimal overpressure ("0.5~1.5MPa") prevent string damage during activation.
✅ Zero Rig Downtime Activation
> Entire activation sequence ("connect with Kelly... pump circulation") executes without tripping.
✅ Dual-Material Ball Compatibility
> Functions with steel balls (standard) or nylon balls (H₂S environments).
✅ API Compliance
> Certified for HP/HT service up to 350°F (177°C) and 15k psi.
