Ball Activated Circulation Valve | Adjustable Shear Pin Coiled Tubing Flow Control Sub

Downhole Tool

Product Overview

The Ball Activated Circulation Valve is a flow control tool designed for coiled tubing downhole intervention strings, matched for use with release dart tools. Construction operators deliver a drop ball inside the coiled tubing string, build internal tubing pressure to push the built-in piston downward, the piston shears pre-installed shear pins, and side circulation ports are exposed to create a communicating flow channel between the coiled tubing inner bore and the annulus, re-establishing stable downhole fluid circulation.

This circulation valve adopts fully customizable shear pin design: both the quantity of shear pins and the shear breaking pressure rating can be modified and adjusted according to customer well construction technical requirements. Two complete service grades are supplied to match diverse reservoir environments: STD standard grade for conventional sweet oil wells without hydrogen sulfide corrosive media, and H₂S sour service grade constructed with sulfur-resistant alloy for high-H₂S corrosive sour gas well working conditions.

The standardized product lineup covers outer diameter sizes ranging from 1-11/16" to 3-1/8", with matched inner diameter and make-up length specifications, equipped with standard AMMT and PAC bottom connection threads for universal compatibility with mainstream coiled tubing connectors and downhole service tools. Custom shear pin quantity, custom shear pressure ratings, inner bore sizes, wall thickness and anti-sulfur passivation coatings are available upon customer technical drawing submission.

Core Features & Advantages

Fully adjustable shear pin performance: both the number of installed shear pins and the shear breaking pressure value can be customized to fit different well depth, formation pressure and coiled tubing construction schemes

Drop ball pressure-driven actuation mechanism: deliver drop ball, build internal tubing pressure to drive piston downward, shear pins break automatically to open side circulation ports, realizing remote circulation switching without complex surface control equipment

Independent side circulation port flow channel design, large flow cross-section after port opening, effectively eliminate downhole fluid flow blockage and quickly rebuild stable annulus circulation:

Dual service grade design: STD standard version for conventional sweet oilfield working conditions, H₂S sulfur-resistant alloy version for highly corrosive high-H₂S sour gas well service

Complete outer diameter series compatible with 1-11/16", 2-1/8", 2-7/8" and 3-1/8" coiled tubing matching assemblies, covering all mainstream small and medium-size coiled tubing intervention service demands:

Simple external threaded connection design, convenient for fast disassembly and assembly with various coiled tubing connectors on site, easy to integrate into bottom coiled tubing tool string:

Precision CNC machined high-strength alloy steel valve body, excellent pressure resistance, erosion and fatigue resistance to extend continuous long-term downhole service cycle:

Multi-dimensional customizable technical parameters, including shear pin quantity, shear breaking pressure, outer diameter, inner bore flow size, bottom thread specification and anti-sulfur surface passivation coatings, to satisfy unique proprietary coiled tubing circulation control requirements:

Application Scenarios

1. Coiled tubing sand washing, well cleaning, gas lifting, perforating and other downhole intervention treatments requiring remote circulation switching control
2. Conventional sweet crude oil well coiled tubing intervention flow control service (STD standard service grade)
3. High-H₂S sour gas well corrosive environment coiled tubing circulation rebuilding remote control operations (H₂S sour service grade)
4. Downhole flow blockage, circulation loss emergency treatment matched with drop-ball and release dart coiled tubing operation tools
5. Long-term circulation switching control and emergency flow channel protection for coiled tubing strings in onshore and offshore oilfields

FAQ

Q1: What is the core function of a Ball Activated Circulation Valve??
The Ball Activated Circulation Valve is a remote circulation switching coiled tubing tool installed in the downhole tool string, matched with release dart tools. Operators drop a ball and build internal tubing pressure to push the piston down, shear pins break to open side circulation ports, creating a flow channel between coiled tubing and annulus to rebuild downhole fluid circulation. Q2: What is the core customizable advantage of this ball activated circulation valve? A2: The quantity of installed shear pins and the shear breaking pressure value can both be fully adjusted and customized according to customer well construction technical requirements, adapting to various well pressure and construction process conditions. Q3: What range of outer diameter sizes do these ball activated circulation valves support? A3: Our standard production lineup fully covers 1-11/16", 2-1/8", 2-7/8" and 3-1/8" outer diameter specifications, compatible with global mainstream small and medium-size coiled tubing matching assemblies. Q4: What is the difference between STD standard grade and H₂S sour service grade? A4: STD standard grade is manufactured for conventional sweet oil wells without hydrogen sulfide corrosive fluid. H₂S sour service grade adopts sulfur-resistant alloy substrate and special anti-sulfur passivation coating to resist chemical corrosion in high-H₂S sour gas well environments. Q5: What is the standard production lead time for bulk purchase orders? A5: All standard PN part numbers are kept in factory inventory, goods can be delivered within 7–15 working days. Customized ball activated circulation valves with special shear pin configurations or custom flow bore dimensions require 20–35 working days production cycle, subject to total order quantity.
