4-Port (4x4 Configuration) Choke Valve Trim - Tungsten Carbide, External Sleeve Style

4-Port (4x4 Configuration) Choke Valve Trim - Tungsten Carbide, External Sleeve Style About

Product Overview

Our 4-Port (4x4 Configuration) Choke Valve Trim is a precision-engineered valve trim component designed for external sleeve over ported cage choke valves. This trim features a 4x4 port flow profile 4 small ports in the lower section and 4 larger ports in the upper section delivering a modified equal percentage flow characteristic for exceptional control across the entire operating range.

The 4 small ports in the lower section provide fine control at low openings, while the 4 larger ports provide capacity for higher flows. This design makes the trim ideal for oil and gas production, well testing, flowback operations, and other applications requiring precise flow control under severe erosive and high-pressure-drop conditions.

Manufactured from premium solid tungsten carbide, our 4x4 choke valve trim offers superior resistance to erosion, abrasion, and corrosion making it the preferred choice for the most demanding oilfield applications where standard trims would wear out quickly.

Key Features

1) 4x4 port flow geometry - 4 diametrically opposed ports provide the highest wear resistance in cage-type flow trims

2) 4 small lower ports + 4 large upper ports - Fine control at low openings + high capacity for higher flows

3) Modified equal percentage flow characteristic - Precise control across the entire operating range

4) Balanced flow pattern - Starts as equal percentage and transitions toward linear

5) Pressure-balanced design - Reduces operating torque and stem loads

6) Solid tungsten carbide construction - Maximum erosion resistance from sand-laden fluids

7) Cartridge-style installation - No internal threads or special tools simplifies field maintenance

8) Metal-to-metal shut-off - Positive shut-off in accordance with ANSI Class IV & V

Technical Specifications

Port Geometry: How It Works

The 4x4 port configuration is designed to optimize both flow control and wear resistance:

4 small ports in the lower section provide the fine control needed at low openings, managing the initial portion of the valves control range with precision.

4 larger ports in the upper section provide capacity for higher flows, ensuring ample flow capacity when demand increases.

4 diametrically opposed ports direct flow into the center of the trim where it impinges on flow from the opposite port, creating a balanced flow pattern that provides the highest wear resistance in cage-type flow trims.

The flow geometry starts as an equal percentage type characteristic and transitions toward linear as the valve opens further.

• Abrasive Service - Ideal for wells with sand production and formation solids

Why Choose Our 4-Port (4x4 Configuration) Choke Valve Trim?

Superior Wear Resistance

The 4 diametrically opposed port design provides the highest wear resistance in cage-type flow trims. Manufactured from solid tungsten carbide, our trim delivers exceptional resistance to abrasive wear from sand and other solid particles entrained in production fluids.

Precision Flow Control

The 4x4 port configuration ensures fine-tuned control over the entire operational range. The 4 small lower ports manage low-opening control with precision, while the 4 larger upper ports provide ample capacity for higher flows.

Balanced Flow Characteristics

Flow is directed through ports into the center of the trim where it impinges on flow from the opposite port. This balanced flow pattern starts as an equal percentage characteristic and transitions toward linear, ensuring stable control across varying flow conditions.

Pressure-Balanced Design

The pressure-balanced trim design reduces operating torque and stem loads, enabling smoother operation and extending the service life of associated components.

Easy Field Maintenance

The cartridge-style installation uses no internal threads or special tools. Maintenance personnel can replace or service the trim quickly and efficiently in the field no specialized training or equipment required.

100% Interchangeable

Our 4-Port (4x4 Configuration) Choke Valve Trim is 100% interchangeable with major OEM external sleeve choke designs, ensuring seamless compatibility with existing equipment.
