When selecting the right valve for your application, it's not just about the valve type or material — the end connection plays a critical role in ensuring reliable performance, ease of installation, and maintenance. The end connection type determines how a valve is fitted into a pipeline and influences factors such as pressure ratings, sealing performance, and long-term system integrity.
In this article, we’ll walk through the most common types of valve end connections, along with their advantages, typical applications, and industry considerations.
1. Threaded (Screwed) Ends
Threaded end valves use screw threads (male or female) to connect with the pipeline.
Common Thread Types:
NPT (National Pipe Thread) – Common in North America
BSPT/BSPP (British Standard) – Used in Europe and Asia
Advantages:
Easy to install and remove
No need for welding
Cost-effective for smaller valves
Applications:
General service pipelines
Allow for easy assembly and disassembly during maintenance.
Systems where welding isn’t feasible due to fire hazards or accessibility
2. Flanged Ends
Flanged valves have machined flanges that are bolted to pipe flanges using gaskets for sealing.
Advantages:
Strong and leak-resistant
Easy to install, remove, or inspect
Standardized dimensions (ASME, DIN, JIS, etc.)
Applications:
Oil & gas, chemical, water treatment, and power plants
Larger pipe diameters
Compatible with standardized piping systems across different regions
3. Welded Ends
Types:
Butt Weld – Ends beveled to allow full penetration welding
Socket Weld – Pipe inserts into recessed area before welding
Advantages:
Strongest and most leak-proof joint
Suitable for high-pressure and high-temperature service
Eliminates need for threaded or bolted joints
Applications:
Power plants, refineries, and critical pipelines
Permanent piping systems
High-purity or hazardous media handling
4. Tri-Clamp / Sanitary Ends
These use a clamping mechanism for quick connection and disassembly, mainly used in hygienic environments.
Advantages:
Tool-free assembly and disassembly
Easy to clean (CIP/SIP compatible)
Ideal for maintaining hygiene
Applications:
Food & beverage
Pharmaceutical and biotech
High purity water systems
5. Compression / Tube Fitting Ends
These ends connect to tubes via compression fittings, providing leak-tight seals without welding.
Advantages:
Quick and clean installation
Ideal for small-diameter piping
No heat or threading required
Applications:
Laboratory and instrumentation systems
Semiconductor industry
Pneumatic controls and gas distribution
Choosing the Right Valve End Connection
When selecting the end connection for your valve, consider the following factors:✅ Pressure and temperature requirements✅ Pipe material and size✅ Application environment (hygienic, corrosive, etc.)✅ Installation and maintenance needs✅ Regional or industry-specific standards
Conclusion
Each end connection type serves a specific need — whether it's ease of maintenance, cost-efficiency, high-pressure sealing, or hygienic performance. At Anson Flow Corp., we offer a wide range of valve end connections tailored to meet the needs of various industries including oil & gas, chemical, semiconductor, and power.

🔥 API 607: Firesafe Valve Certification
API 607 is a key firesafe standard issued by the American Petroleum Institute. It outlines fire safety requirements for quarter-turn valves with non-metallic seats. These valves must retain integrity during and after fire exposure, making this certification essential in industries such as oil & gas, petrochemical, and hazardous chemical storage.
Anson Flow provides a wide range of API 607-certified firesafe valves, ensuring reliable operation in high-risk and flammable environments.

In industrial flow control systems, selecting the right valve is crucial for safety, efficiency, and cost-effectiveness. Gate, globe, ball, needle, check, and butterfly valves are among the most commonly used, each with unique features and applications suited to different system demands.
1. Gate Valves
Gate valves are designed for on/off control. They feature a linear motion disk that moves up and down to start or stop flow. Ideal for full-open or full-close operations, gate valves are commonly used in pipelines where minimal pressure drop is required and infrequent operation is expected.
2. Globe Valves
Globe valves are suitable for throttling and regulating flow. Their spherical body and internal baffle allow for precise flow control. Frequently used where flow needs regular adjustment, globe valves are preferred for applications that require flow resistance management.
3. Ball Valves
Ball valves use a rotary ball with a hole through the center to control flow. They are favored for their tight sealing, fast shutoff capabilities, and low maintenance. Ball valves are ideal in applications requiring quick operation and where pressure drop must be minimized.
4. Needle Valves
Needle valves offer extremely precise flow control through a slender, tapered point at the end of the valve stem. Commonly used in instrumentation and fine metering applications, they are ideal when small flow rates must be regulated with high accuracy.
5. Check Valves
Check valves allow flow in only one direction and automatically prevent backflow. They do not require manual operation and are essential in systems where reverse flow could damage equipment or disrupt processes. Applications include pumps, compressors, and pipelines with varying pressures.
6. Butterfly Valves
Butterfly valves use a rotating disc to regulate flow. They are compact, lightweight, and provide fast shutoff. Suitable for large diameter pipes, butterfly valves are widely used in water treatment, HVAC, and applications requiring space-efficient valve solutions with moderate pressure control.
Conclusion
Each valve type plays a critical role depending on the application's requirements:
· Gate valves are ideal for infrequent on/off service.
· Globe valves excel at precise throttling.
· Ball valves offer quick shutoff and reliability.
· Needle valves deliver ultra-fine flow control in instrumentation.
· Check valves ensure unidirectional flow and protect equipment.
· Butterfly valves provide a lightweight, efficient option for fast shutoff in large-scale systems.
At Anson Flow, we offer a comprehensive range of industrial valves designed to meet various operational needs. Whether your system demands precision control, space-saving design, or rugged durability, our experts are here to help you select the right valve solution.
Industries such as chemical, petrochemical, and oil & gas often operate in hazardous environments, where safety and equipment reliability are paramount. Valves play a critical role in flow control, and improper selection may lead to gas leakage, explosions, or environmental hazards. Here's how to choose the right valve for hazardous areas.
1.Select Explosion-Proof Actuators and Compatible Ball Valves for Hazardous Applications
When dealing with hazardous areas, it's critical to choose explosion-proof actuators that ensure safe automation. Equally important is selecting the right ball valve to match the actuator and process environment.
Ball valves are widely used in hazardous applications due to their compact design, tight shut-off, and easy of operation. Depending on your needs, you may consider:
· Fire-safe ball valves for emergency shutdown in fire-prone environments
· Metal seated ball valves for high-pressure or high-temperature systems
· Trunnion-mounted ball valves for large-diameter or high-torque operations
· Cryogenic ball valves for LNG and low-temperature applications
Combining an CE-certified actuator with a robust industrial-grade ball valve improves both system safety and operational efficiency.
2. Choose Corrosion-Resistant Valve Materials
Hazardous areas often involve corrosive chemicals. Therefore, materials like 316 stainless steel, Monel, or Hastelloy are recommended for valve bodies and internal components.
3. Seal Design and Leak-Proof Testing
Valves with high-performance sealing systems and verification through Helium Leak Testing can ensure zero leakage and minimize risks in critical operations.
4. Quality Certification and Test Reports
Choose manufacturers with certifications such as ISO 9001, API 607, and Fugitive Emission. Request documents like MTC (Material Test Certificate) and pressure test reports to verify quality compliance.
Conclusion
Choosing the right valve for hazardous areas ensures the safety and stability of your operation. Anson Flow offers a wide range of explosion-proof, corrosion-resistant, and leak-proof industrial valves tailored for harsh chemical applications. Feel free to contact us for more information!
