Product Introduction: Hydraulic Valve Extractor Assembly Hydraulic valve extractor assembly is a dedicated hydraulic tool for dismounting valve assemblies inside triplex mud pump fluid ends, widely used in oil drilling, geological exploration and horizontal directional trenchless construction. It solves the difficulty of removing stuck valve discs, valve seats and spring guides after long-term high-pressure mud scouring, greatly improving on-site maintenance efficiency. This assembly consists of hydraulic power unit, pulling cylinder, puller claw, positioning adapter and high-pressure connecting hose, all key load-bearing parts forged from high-strength alloy steel and subject to fatigue pressure testing. The integrated hydraulic drive generates stable axial pulling force, which evenly acts on the valve fitting without damaging valve seat sealing surfaces, pump cavity inner walls and other precision parts. Multiple matched positioning adapters are designed for different models of mud pump valve assemblies, with high universality and interchangeability. Self-locking clamping structure prevents slipping during pulling operation, effectively avoiding safety accidents caused by sudden ejection of valve parts under residual pressure. The hydraulic system adopts oil-filled anti-leakage design, with stable output pressure and adjustable pulling force to cope with severely stuck valve components blocked by rock cuttings and mud scale. All metal surfaces are treated with rust-proof and wear-resistant coating, adapting to muddy, humid open-air construction environments. Lightweight split structure is easy to carry and operate by a single worker, eliminating labor-intensive manual knocking and prying that easily cause component scrapping. It shortens the downtime for fluid end overhaul, reduces the scrap rate of valve seats and pump bodies, and cuts comprehensive maintenance costs. As a special maintenance tool for mud pump fluid end, it realizes safe, fast and damage-free disassembly of valve assemblies, ensuring efficient progress of drilling and trenchless construction.
