PVV-01 (3WAY) is a vacuum ball valve featuring a SUS316 body with a 3WAY ball construction. With a configuration that allows branching, merging, and switching of vacuum lines using a single valve, it is used for 3-way flow control of vacuum piping in semiconductor, display, solar, and laboratory applications.

Frequently Asked Questions
How do I distinguish between L port and T port in the vacuum 3-way ball valve?
L port is used for simple switching applications selecting one of two paths, and T port is used for manifold applications requiring simultaneous branching and merging. Choose L port for simple switching process sequences, T port for simultaneous multi-path control.
How do I choose between ball valves and bellows valves in vacuum lines?
Ball valves are suitable for path switching in general HV lines thanks to their simple structure. Bellows valves are advantageous in high-vacuum, corrosive gas, and long-term high-reliability environments since the stem seal is isolated from the atmosphere, but with complex structure and high price.
How do I choose between manual and automation?
PVV-01 (3WAY) is supplied with bare shaft specification, allowing the field to attach the required drive method among manual handle, pneumatic, or electric. Thanks to the ISO5211 direct mounting pad, initial manual operation can later be expanded to automation.
What level of vacuum can it be used to?
It is designed for path switching in the general high vacuum (HV) range. Environments requiring ultra-high vacuum (UHV) require separate specification review; let us know your operating environment and we will guide you on suitability and options.
