3-Piece Ball Valve Overview
This section provides technical specifications and details for a 3-piece ball valve, highlighting its components, materials, and operational features. The valve is available in sizes ranging from DN 08 to DN 150 (1/4" to 6"). Key components include the body, stem, seats, and seals, made from materials such as stainless steel (316L), carbon steel, PTFE, and PEEK. The valve design ensures optimal sealing and pressure handling, with built-in body seals for internal and external tightness.

Material and Temperature Range
Various seat materials are available, including TFM 1600, PTFE with 20% PEEK, and PEEK, each with specific temperature ranges. For example, TFM 1600 seats operate between -50°C and +190°C, while PEEK seats handle 0°C to +280°C.

Approvals and Options
The valve complies with standards such as PED 97/23/CE and TA-Luft for fugitive emissions. Options include ATEX certification and specific configurations for cavity relief in open or closed positions.

Pressure/Temperature Diagrams
Pressure and temperature diagrams are provided for full bore sizes, detailing the mechanical strength of the body and seats under various conditions.

Connection and Material Options
Connection types include loose ends, butt welding, and socket welding, with material options such as carbon steel, stainless steel (316L, 304L), and super duplex alloys.

Actuation Systems
The document details pneumatic actuation systems, including PS4, PY4, and PZ4 models. Each model is available in single and double-acting configurations, with specific pressure ratings and operational parameters. The TRUTORQ system is highlighted for its spring return and double-acting capabilities.

Applications and Recommendations
The valves are suitable for various industrial applications, with specific configurations for cryogenic services and standard pressure conditions. Recommendations include maintaining service pressures within specified limits to ensure optimal performance.

Specifications for Application Ball Valves
The document provides specifications for application ball valves ranging from sizes DN 08 to DN 150 (1/4" to 6"). The valves are designed with a PN 25 jacket and threading options. Key dimensions and volumes for thermal envelopes and steam jackets are provided for each size.

Materials and Construction
The valves are constructed using materials such as 1.4409 and 1.4404 for the body and steam jacket, respectively, with ASTM equivalents CF-3M and 316L. Additional components include PTFE seals and various stainless steel grades for other parts.

Installation and Operation
Vertical mounting is recommended for upward flow, with a directional arrow marked on the body. For horizontal mounting, a minimum pressure difference of 1 bar is required to ensure sealing. Optional features include ATEX certification, degreased versions for oxygen applications, and cryogenic applications.

Actuation Systems
The document details pneumatic and electric actuation systems, including C-Type, E-Type, and CNi-Type actuators. These systems are designed to minimize air consumption and ensure reliable operation. Features include a removable Body Adaptor Kit for direct mounting and a unique nickel impregnation coating for enhanced durability.

Additional Features
Optional features include the TRUVISION indicator for local visual indication, triple shaft bearings to eliminate metal contact, and patented spring designs for enhanced performance. The document emphasizes the flexibility and reliability of the actuator configurations.

Conclusion
This comprehensive guide provides essential information for selecting and operating various types of valves, ensuring compatibility with specific industrial applications and compliance with relevant standards.
