Ball Valves

Ball Valves for Vacuum, Process, and Industrial Applications

ThinFilmMaterials offers a wide selection of Ball Valves engineered for high vacuum, clean gas, and process control systems. These valves are ideal for shut-off and flow control in roughing lines, forelines, and general vacuum plumbing. Featuring low torque operation and quick quarter-turn actuation, Ball Valves provide a reliable and compact solution for systems requiring frequent cycling.

Our Ball Valves are constructed using corrosion-resistant materials such as 316L stainless steel and brass, and are available with a variety of end connections including tube stub, VCR®, compression, and ASA flange types. Whether for laboratory vacuum setups or industrial gas lines, our Ball Valves deliver leak-tight sealing and long service life.

Key Features of Ball Valves:

• Construction: 316L stainless steel, brass, or aluminum

• End connections: Tube weld, ASA flange, VCR®, compression

• Valve type: 2-way and 3-way ball configurations

• Pressure range: Vacuum to 3,000 psi depending on model

• Temperature rating: Up to 200°C with PTFE seals

Applications:

Ball Valves are widely used in:

• Foreline and roughing line isolation

• Gas distribution and purge systems

• Thin film deposition and PVD/CVD tools

• Analytical instruments and gloveboxes

• Semiconductor and vacuum chamber systems

ThinFilmMaterials also supports custom Ball Valve assemblies with modified port lengths, special actuation handles, and vacuum-cleaned preparation for cleanroom environments. Every valve is designed to provide smooth operation, minimal dead space, and long-term sealing performance.
