Product Overview
The Bypass Valve coiled tubing PDM motor matched flow divider valve is a special flow distribution control tool developed for coiled tubing downhole drilling motor flow regulation and annulus cuttings transport improvement remedial workover operations.
This bypass valve is specially matched for combined use with positive displacement drilling motors (PDM / screw drilling motors); the valve body can precisely limit and control the effective liquid flow volume passing through the PDM motor, ensuring the drilling motor operates under stable rated flow conditions. All redundant excess circulating fluid that exceeds the motor allowable flow range is diverted into the wellbore annulus through multiple built-in jet nozzles; the increased annulus fluid flow velocity greatly enhances the return fluid carrying capacity for downhole rock cuttings and solid debris, realizing efficient wellbore debris and cuttings removal. Two core adjustable parameters are reserved for users to customize diversion flow volume: the bore hole orifice diameter size of each individual nozzle, and the total number of installed nozzles, which can be freely modified to adapt to different downhole construction circulation flow rate demands.
The Bypass Valve has no complex internal movable friction components, spring energy storage assemblies or differential pressure release mechanisms, with extremely simplified wellsite operation flow and low maintenance cost; construction crews only need to connect the bypass valve above the PDM motor in the coiled tubing tool string, run the whole tool string down along the tubing inner wall to the target downhole drilling construction section, start the surface circulation pump, the bypass valve will automatically split the circulating fluid into two paths: fixed flow through the PDM motor for drilling power generation, surplus flow diverted into the annulus via nozzles to boost cuttings carrying efficiency, no additional auxiliary operation steps such as drop ball delivery or shear pin impact jarring are needed, shortening wellsite operation time and reducing human error risks.
The standardized product lineup covers outer diameter sizes ranging from 1-3/4" to 2-7/8", with complete outer diameter specification series to match different tubing inner diameter constraint conditions and various coiled tubing downhole drilling construction demands. All standard specifications adopt standard working condition configuration; custom outer diameter, nozzle orifice diameter, nozzle total quantity and base material corrosion resistance grade customization are available upon customer technical drawing submission.

Core Features & Advantages
PDM Positive Displacement Drilling Motor Matched Combined Use Design: The bypass valve is specially designed for matched combined use with positive displacement drilling motors (PDM / screw drilling motors); the valve body can precisely limit and control the effective liquid flow volume passing through the PDM motor, ensuring the drilling motor operates under stable rated flow conditions to maintain constant torque output performance.
Dual Adjustable Nozzle Parameter Customization Design: Two core adjustable parameters are reserved for users to customize diversion flow volume: the bore hole orifice diameter size of each individual nozzle, and the total number of installed nozzles, which can be freely modified to adapt to different downhole construction circulation flow rate demands, realizing flexible adjustment of bypass diversion flow volume.
Surplus Fluid Annulus Diversion & Annulus Flow Velocity Boost Design: All redundant excess circulating fluid that exceeds the motor allowable flow range is diverted into the wellbore annulus through multiple built-in jet nozzles; the increased annulus fluid flow velocity greatly enhances the return fluid carrying capacity for downhole rock cuttings and solid debris, realizing efficient wellbore debris and cuttings removal.
Full Outer Diameter Size Range Coverage: The applicable outer diameter size range of the PDM motor matched bypass flow divider valve covers 1-3/4" to 2-7/8", with complete outer diameter specification series to match different tubing inner diameter constraint conditions and various coiled tubing downhole drilling construction demands.
Ultra-Simplified Wellsite Operation Logic: The bypass valve has no complex internal movable friction components, spring energy storage assemblies or differential pressure release mechanisms, the operation flow is highly streamlined: only need to connect the bypass valve above the PDM motor in the coiled tubing tool string, run the whole tool string down along the tubing inner wall to the target downhole drilling construction section, start the surface circulation pump, the bypass valve will automatically split the circulating fluid into two paths: fixed flow through the PDM motor for drilling power generation, surplus flow diverted into the annulus via nozzles to boost cuttings carrying efficiency, no complex auxiliary operation steps such as drop ball delivery or shear pin impact jarring are needed to shorten wellsite operation time and reduce human error risks.
Low Routine Maintenance Design: The integral cylindrical alloy steel tool body eliminates vulnerable split assembly movable wear parts; after each downhole drilling construction operation, only simple surface nozzle orifice debris cleaning and internal flow passage blockage flushing inspection are required, no complex disassembly, internal nozzle component replacement or spring preload adjustment maintenance procedures, greatly reducing daily maintenance labor and spare parts inventory cost.
