Product catalog summary

Specifications:
The document details specifications for VSS ball valves, covering sizes from ½” to 4” with connection types including clamped, butt weld, and tank bottom. These valves adhere to ASME-BPE guidelines to minimize turbulence and pressure drop.

End Connections:
Valves feature interchangeable end caps for clamped and butt weld connections, machined from bar stock to avoid welded tube extensions.

Surface Finish:
Internal surfaces have a finish of 0.5 micron Ra or better, with mirror-polished external surfaces. Enhanced and electropolished finishes are available upon request.

Seat Material:
Standard seat material is TFM PTFE, compliant with FDA and USP Class VI, but unsuitable for steam service. Alternatives include EPDM, FKM, FEP, and FKKM.

Marking:
Valves are marked with the AR logo, code, material, size, maximum operating pressure (30 bar), CE mark, and traceability code. Customer-specific information can be added.

Pressure/Temperature Rating:
Valves operate from vacuum to 30 bar and -10°C to 150°C, complying with European Directives 97/23/CE (PED) and 94/9/CE (ATEX).

Operator Options:
Options include a manual handle or ISO NAMUR mounting pad for pneumatic actuators, with quarter-turn operation.

TFM PTFE Material:
TFM is a modified PTFE offering improved particle fusion and smoother sealing, compliant with 3A Sanitary, FDA, and USP23 Class VI standards.

Application and Benefits:
The "TB" Series Flush Tank ball valve is ideal for tank bottom applications, minimizing dead space and facilitating easy actuator clearance. It provides high flow rates, quick operation, and easy automation, with an economical and flexible design.

Standards and Operating Conditions:
The VSS-TB-BW ball valve complies with PED 97/23/CE, operating from vacuum to 6 bar and -10°C to 150°C. Special executions are available.

Design Features:
The three-piece sanitary design allows in-line maintenance, featuring self-aligning clamp connections, precision-machined balls, and antistatic devices for electrical continuity. Various seat materials are available for different applications.

tFmtm as a seating material For HigH purity valves AR Inox High Purity ball valves utilize Dyneon™ TFM PTFE as a standard seating material. What is TFM™ ? TFM is chemically modified PTFE that fills the gap between conventional PTFE and melt-processable PFA. According to ASTM D 4894 and ISO Draft WDT 539-1.5, TFM is classified as a PTFE. TFM-PTFE is a second-generation modified polytetra-fluoro-ethylene (PTFE) that maintains the exceptional chemical and heat resistance properties of conventional PTFE, but with significantly lower melt viscosity. This property results in better particle fusion...
