Butterfly Valves:
Description:
These manual butterfly valves provide a cost-effective alternative to bellows-sealed gate valves, offering rapid, quarter-turn actuation from fully closed to fully open. A patented self-centering disk design ensures even pressure distribution across the Viton O-ring seal, significantly reducing O-ring scuffing and rolling to extend service life. Combining quick operation, a compact footprint, and a highly minimized gas path, these valves are the preferred choice for a wide range of high-vacuum applications.
These AVT Products vacuum butterfly valves are engineered for high-integrity isolation, delivering an exceptionally low leak rate typically on the order of times 10^-9 std. cc/sec Helium. Constructed from premium stainless steel, these manually operated valves feature standard ISO-KF vacuum flanges for seamless, secure integration into your system. Their low-profile design provides a high-conductance pathway, making them an ideal choice for reliable, clean vacuum process control.
Right Angle Manual Bellows Valve:
Description:
This manually operated, 90-degree right-angle Ideal Vacuum Super-Seal bellows valve features standard KF flanges on both the inlet and outlet ports, allowing for 360-degree rotational orientation during installation. Engineered for high-vacuum applications 10^-5 mbar and rated to withstand positive pressures up to 60–80 psi, this valve delivers an ultra-low helium leak rate of 10^-9 mbar l/s. The valve body and internal mechanisms are constructed from premium 304L stainless steel, paired with Viton O-rings for the bonnet and poppet seals. Designed for low-friction, abrasion-free operation, the polymer elastomer seals ensure thousands of repeatable cycles. This high-conductance valve maximizes gas flow rates, can be mounted in any orientation, and is bakeable up to 150°C.
Ball valves:
Description:
These manually operated ball valves combine rapid, quarter-turn actuation with high gas throughput and maximum conductance. Engineered for efficient flow control, they actuate fully from on to off with a simple 90-degree handle rotation. Constructed from durable stainless steel, these valves are designed to maintain an exceptionally low helium leak rate, typically on the order of 1X10^-7 std. cc/sec. They feature standard NW-10, NW-16, and NW-25 flanges for fast, secure integration into your vacuum system.
