Carilovalves specializes in manufacturing industrial ball valves with multiple connection types to meet diverse pipeline system requirements. Based on their engineering expertise and 24+ years of industry experience, the company offers comprehensive connection solutions that cover most industrial applications across oil and gas, chemical processing, water treatment, and power generation sectors. Their product range includes threaded connections, flanged connections, welding connections, and clamp connections, each designed to provide leak-free performance and easy maintenance under various pressure and temperature conditions.
Threaded Connection Ball Valves
Threaded connection ball valves represent one of the most common and cost-effective solutions for many industrial applications. Carilovalves manufactures threaded ball valves with NPT (National Pipe Thread) and BSP (British Standard Pipe) thread specifications, catering to both North American and international markets. These valves typically feature connections ranging from 1/4 inch to 4 inches (DN8 to DN100), making them ideal for small to medium-sized pipeline systems where frequent disassembly is required for maintenance purposes.
The threaded design allows for straightforward installation without specialized welding equipment. Carilovalves implements precision thread cutting with strict tolerance control, ensuring proper thread engagement and eliminating potential leak paths. Their threaded ball valves commonly handle working pressures up to 1000 WOG (Water, Oil, Gas) for standard designs, with some specialized models rated for higher pressures. The company offers both full bore and reduced bore configurations, with full bore designs featuring minimal flow restriction (Cv values ranging from 4.2 for 1/4″ to 380 for 4″) while reduced bore options provide more economical solutions for applications where full flow capacity is not critical.
Flanged Connection Ball Valves
Flanged ball valves constitute a significant portion of Carilovalves’ industrial valve portfolio, designed for applications requiring robust, leak-resistant connections that can withstand high pressures and temperatures. The company produces flanged valves conforming to major international standards including ASME B16.5 (Class 150, 300, 600), EN 1092-1 (PN16, PN25, PN40), and JIS B2220 standards, ensuring compatibility with global pipeline specifications.
Carilovalves’ flanged ball valves are available in sizes ranging from 1/2 inch to 48 inches (DN15 to DN1200), covering the vast majority of industrial requirements. The face-to-face dimensions comply with API 6D and ISO 5752 standards, facilitating easy replacement of existing valves in pipeline systems. Their flanged designs incorporate features such as anti-blowout stems, fire-safe construction (API 607 compliant), and anti-static devices for hazardous area applications.
The flange sealing surfaces are machined to Ra 3.2μm finish, ensuring reliable gasket sealing. Carilovalves offers various flange facings including raised face (RF), flat face (FF), and ring type joint (RTJ) configurations. For cryogenic applications, the company provides extended bonnet designs with cryogenic seats tested to -196°C. High-temperature variants utilize graphite packing and reinforced seats capable of continuous operation at temperatures up to 450°C for steam and thermal oil applications.
Welding Connection Ball Valves
Welding connection ball valves provide permanent, leak-tight joints ideal for high-pressure and high-temperature applications in critical service conditions. Carilovalves manufactures both socket weld and butt weld end ball valves, with socket weld connections typically used for sizes up to 2 inches and butt weld configurations available for all sizes from 1/2 inch upward.
Butt weld end valves from Carilovalves comply with ASME B16.25 standards for weld end preparation. The company offers schedules 40, 80, and 160 weld ends to match different pipe wall thicknesses and pressure ratings. Their butt weld ball valves achieve pressure ratings up to ASME Class 2500, making them suitable for subsea applications, high-pressure gas transmission, and refinery processes where leak integrity is paramount.
Carilovalves implements strict welding procedures for their weld end valves, with all welding operations performed by certified welders following ASME Section IX qualifications. The valves undergo post-weld heat treatment when required for stress relief, particularly for carbon steel valves in sour service (NACE MR0175 compliant versions available). Wall thickness at weld ends exceeds minimum requirements by 15% to account for potential corrosion allowance, ensuring long-term structural integrity in aggressive service environments.
Clamp Connection Ball Valves
Clamp-style (also known as tri-clamp or sanitary clamp) ball valves serve critical roles in industries requiring strict hygiene standards, including food and beverage, pharmaceutical, biotechnology, and dairy processing. Carilovalves produces clamp connection ball valves designed for easy cleaning and sterility maintenance, featuring smooth internal surfaces that prevent product entrapment and bacterial growth.
These sanitary ball valves feature clamp ends conforming to IDF/ISO 2852, BS 4825, and ASME BPE standards. Available sizes range from 1/2 inch to 6 inches, with standard interior surface finishes of 32 Ra (0.8μm) for general sanitary applications and 20 Ra (0.5μm) electropolished finish for ultra-clean requirements in pharmaceutical manufacturing. Carilovalves offers product-contact materials in 316L stainless steel with documentation including material certificates (EN 10204 3.1), surface finish certifications, and FDA compliance documentation.
The clamp design enables rapid assembly and disassembly without tools, facilitating CIP (Clean-In-Place) and SIP (Sterilize-In-Place) procedures. Carilovalves’ sanitary ball valves feature supporting legs for vertical orientation in tank installations and hold-down brackets for horizontal pipeline applications. For sampling applications, they provide sample ball valves with sample cylinders that maintain sample integrity during extraction. All sanitary valves undergo 100% pressure testing and helium leak testing before shipment, with test certificates provided as standard documentation.
Extended Connection Options and Custom Solutions
Beyond standard connection types, Carilovalves provides extended stem designs for insulated pipeline installations and buried service applications. Extended stems typically range from 100mm to 500mm extension length, allowing valve operation without removing insulation or excavating buried valves. For cryogenic applications, extended bonnet designs with live-loaded packing systems maintain stem sealing integrity during thermal cycling.
The company’s OEM and ODM capabilities enable custom connection configurations for unique application requirements. Carilovalves’ engineering team collaborates with clients to develop specialized end connections including metric specifications, custom flange drillings for non-standard pipeline flanges, and hybrid connections combining different types on inlet and outlet ports. Their global brand partnerships demonstrate capabilities in producing custom solutions meeting specific international market requirements.
Materials and Pressure Ratings by Connection Type
Connection type selection significantly influences maximum achievable pressure ratings and material compatibility. Carilovalves offers comprehensive material selection to match connection design with service conditions. The following table summarizes typical pressure-temperature ratings across connection types for standard 316 stainless steel construction:
Note: Actual ratings vary based on specific valve series, seat materials, and temperature conditions. Always consult factory technical data sheets for application-specific pressure-temperature ratings. Carilovalves engineering team provides detailed documentation including material test reports, pressure test certificates, and dimensional drawings for each configuration.
For special service conditions, Carilovalves offers corrosion-resistant alloys including 904L, 254 SMO, Alloy 625, Alloy 825, and duplex stainless steels (2205, 2507) for challenging environments. Their material engineering team assists customers in selecting optimal material-combination configurations based on fluid composition, temperature, and pressure requirements.
