Description
DEENPU Adjustable Choke Valve is engineered for precise, continuous flow control in high-pressure fracturing and flowback operations. Built to API 6A specification with NACE MR-0175 sour-service compliance, the DEENPU choke valve delivers reliable throttling performance across a wide range of wellhead and manifold applications. The fully-lined carbide stem and tungsten carbide trim provide exceptional wear resistance in the most abrasive service conditions.
Available in 2″ and 3″ body sizes with Figure 1502 hammer union end connections, the DEENPU adjustable choke valve is designed for fast rig-up and rig-down in mobile wellsite operations. The forged alloy steel body, stainless steel internals, and tungsten carbide wear surfaces are engineered for long service life in both standard and sour (H₂S) service environments.
Key Features
- Continuous, fine-adjustable flow control — ideal for fracturing and flowback operations
- Fully-lined carbide stem for superior wear and erosion resistance
- Figure 1502 hammer union end connections for fast rig-up/rig-down
- Forged alloy steel body for high-pressure integrity
- Stainless steel and tungsten carbide internal trim
- Available in standard service (15,000 psi) and sour gas service (10,000 psi) configurations
- NACE MR-0175 / ISO 15156 compliant materials for H₂S environments
- PSL-3 product specification level
- Positive locking handle with vernier scale for repeatable flow settings
- Field-replaceable wear parts (seat, stem, packing) for reduced downtime
- Pressure tested to maximum working pressure before shipment

How It Works
The adjustable choke valve regulates fluid flow by progressively restricting the orifice area between the stem tip and the seat. As the handwheel turns, the carbide-lined stem moves linearly, changing the gap between the stem and the seat. This creates a variable restriction that can be precisely set to any flow rate between fully open and fully closed, with a vernier scale on the handle allowing operators to return to specific set points repeatedly.
The tungsten carbide overlays on both the stem and seat provide exceptional resistance to erosion from sand, proppant, and other abrasive materials commonly encountered during fracturing operations. The Figure 1502 hammer union end connections allow the valve to be installed or replaced quickly without special tools, making it ideal for mobile wellsite service.
Applications
- Hydraulic fracturing (frac) flowback operations
- Wellhead testing and clean-up
- Choke and kill manifolds (drilling and production)
- Stream injection and water disposal wells
- Wellhead production flow control
- Sour gas (H₂S) wellhead service
- Mobile wellsite service and workover rigs
- Combined with positive choke valves in dual-run manifold configurations
