7. Design Features & Benefits (Halliburton Lo-Torc® Replacement)

Feature Description Benefit
Cylindrical Plug Design Cylindrical (non-tapered) plug eliminates wedging action Prevents jamming under pressure; significantly reduces operating torque
Pressure-Balanced Plug Identical stem seals at both ends Eliminates need for thrust bearings; low torque even at 15,000 psi
Split Inserts Design Inserts are parted into identical halves, tapered OD to match body cavity; ID precision ground to plug diameter Firm uniform clamping; easy adjustment; no lapping required
Floating Plug & Inserts Assembly Assembly “floats” downstream under pressure Compensates for body deflection; seal improves with pressure
Reduced Bearing Area Raised boss on inserts is only contact area Minimizes frictional forces; reduces operating torque
In-Line Maintenance All parts replaceable with valve body left in line Minimal downtime; no special tools required
Dual-Function Lubrication System Grease fitting with lubrication chambers above/below plug Lubricates and enhances sealing simultaneously
Metal-to-Metal + Elastomer Sealing Precision cylindrical fit + O-ring seals Reliable leak-proof operation under extreme conditions
Clear Open/Close Indication Apparent open/close identification and position limiting mechanism Improved operational safety; quick visual status verification
Multiple Actuation Options Handle, pneumatic, hydraulic or gear operators available Flexible integration into manual or automated systems
