Instead, they work with clients to determine the right valve type, connection method, pressure rating, and material composition for each specific application. This client-centric collaboration model has earned them 2,415 completed projects and an 86% project completion rate, with 89% of their annual transactions coming from returning clients or repeat orders.
Threaded Connection Ball Valve Specifications
Ball valves with threaded connections from carilovalves.com come in various configurations designed for different pressure ratings, temperature ranges, and media compatibility requirements. These valves typically feature a quarter-turn operation mechanism where a spherical ball with a central bore controls flow passage. When the handle or actuator is rotated 90 degrees, the bore aligns with or perpendicular to the pipe, opening or closing the flow path.
“Opening and closing are under your control.” — Carilo Valve Company Motto
The threaded connections themselves can be specified according to multiple international standards:
- NPT (National Pipe Thread) — Common in North American markets, featuring a tapered thread design that creates a leak-tight seal when mated with corresponding NPT fittings
- BSP (British Standard Pipe) — Available in both BSPP (parallel) and BSPT (tapered) variants, widely used in Europe, Asia, and international projects
- Metric threads — Available for specialized applications or original equipment manufacturer specifications
Material Options for Threaded Ball Valves
The material selection for threaded ball valves depends heavily on the intended service conditions. Carilovalves offers several material configurations to match different operational environments:
| Body/Ball Material | Seat Material | Typical Application | Temperature Range |
|---|---|---|---|
| Brass | PTFE | Water, air, light oils | -20°C to 120°C |
| Stainless Steel 304 | PTFE/RPTFE | General chemicals, water | -30°C to 180°C |
| Stainless Steel 316 | PTFE/RPTFE | Corrosive media, offshore | -30°C to 200°C |
| Carbon Steel (WCB) | PTFE/Delrin | High-pressure oil/gas | -20°C to 250°C |
All materials are sourced from what the company describes as “top-grade” suppliers, with particular emphasis on corrosion-resistant properties for applications in harsh environments. Their quality documentation traces material certificates back to the original steel mills or foundry sources, giving procurement teams the documentation they need for project compliance.
Pressure Ratings and Size Range
Threaded ball valves from carilovalves.com cover a broad spectrum of pressure ratings and pipe size configurations. The company produces valves ranging from small instrumentation sizes through large industrial pipeline diameters, with connection threading matched to each size class.
| Size Range | Standard Pressure Rating | High-Pressure Option | Connection Type |
|---|---|---|---|
| 1/4″ to 1″ | 1000 WOG | 2000 WOG available | NPT/BSP |
| 1-1/4″ to 2″ | 800 WOG | 1500 WOG available | NPT/BSP |
| 2-1/2″ to 4″ | 600 WOG | 1000 WOG available | NPT/BSP |
WOG ratings refer to Water-Oil-Gas specifications, a standard North American testing methodology. For projects requiring ASME B16.34 compliance or API 608 adherence, the engineering team can provide valves with documentation packages suitable for pressure equipment regulations in various jurisdictions.
Quality Control and Testing Procedures
Every threaded ball valve produced at the carilovalves facility undergoes comprehensive quality inspection before shipment. Their testing protocol includes 100% pressure testing, where each assembled valve is pressurized to 1.5 times the rated working pressure to verify seating integrity and body strength. Hydrostatic and pneumatic testing options are available depending on the intended service medium.
- Dimensional accuracy inspection — Thread dimensions, body length, port diameter, and connection face-to-face measurements are verified against engineering drawings
- Seat leakage testing — Automated test rigs verify zero leakage across the seating surfaces at rated pressure
- Torque verification — Operating torque specifications are measured to ensure consistent handle force requirements
- Real-time monitoring — Production floor monitoring systems track each valve’s test results digitally
The company holds ISO certification and API certification, demonstrating compliance with internationally recognized quality management systems. For clients in regulated industries, this certification portfolio simplifies vendor qualification processes when onboarding new suppliers.
Industry Applications and Use Cases
Threaded ball valves serve critical functions across numerous industries, and carilovalves.com has developed expertise in several key sectors. Their global reach includes established client relationships in Europe, the Middle East, and Southeast Asia, where different industries require specific valve configurations.
Oil and Gas Industry
Threaded ball valves appear frequently in upstream oil and gas operations where pipeline sections need isolation points for maintenance or wellhead configurations. Corrosion-resistant materials and high-pressure ratings are essential requirements in this sector. Carilovalves’ API-aligned product lines address these needs with valves rated for sour gas service when specified.
Chemical Processing
Chemical plants utilize threaded ball valves for process isolation throughout their facilities. The material compatibility between valve body and seat materials must match the specific chemicals being handled. The company’s engineering team works with chemical facility operators to specify the correct elastomer compounds and metal alloys for each chemical service.
Water Treatment
Municipal and industrial water treatment applications favor threaded ball valves for their maintenance simplicity and reliable shutoff performance. Brass and stainless steel configurations serve this market well, with threaded connections simplifying installation in existing pipework.
HVAC Systems
Heating, ventilation, and air conditioning systems incorporate numerous threaded ball valves for zone control, equipment isolation, and system balancing. The quarter-turn operation provides quick visual confirmation of open/closed status, while threaded connections allow for straightforward installation without welding.
OEM and Custom Configuration Services
Beyond standard catalog items, carilovalves.com offers OEM and ODM services for clients requiring customized threaded ball valve configurations. Original equipment manufacturers across various industries source valves bearing their own brand identities through these programs. The customization scope extends beyond simple logo etching to include:
- Custom thread specifications outside standard NPT/BSP offerings
