HVA Gate Valves

HVA is the premier provider of vacuum gate valve products and is the only vacuum gate valve manufacturer located in the USA. The HVA manufacturing facility located near Reno, NV is a modern facility housing state-of-the-art CNC and other tooling for precision manufacturing. Sizing capability ranges from 16 mm to 800 mm on gate valves and 2 meters on rectangular/slit valves. The body along with all major internal components of the stainless steel valves are vacuum furnace brazed in-house. This eliminates the possibility of virtual leaks along with minimizing distortion of the valve body found in conventionally welded or cast valves. All products are 100% first article inspected to ensure the highest quality product.

High Vacuum Gate Valves

High Vacuum Gate Valves provide isolation for high vacuum pumps, such as turbo pumps, ion-pumps, or cryo-pumps. Gate Valves are provided in manual and pneumatic designs, and for clean and low outgassing high vacuum applications. Flanges can be either NW, ISO or CF(ConFlat). Gate Valves with 3-position actuation are available for pressure control process steps.

Ultra-High Vacuum Gate Valves

Ultra-High Vacuum (UHV) Gate Valves provide low outgassing isolation for applications needing ultra-high vacuum or vacuum bake-out. CF Flanged Gate Valves use a knife edge seal with a copper gasket bonnet seal. Both manual and pneumatic designs are available. Bake-out temperatures can be as high as 200°C with the valve open, and 150°C with the valve closed.

21200 Series
Stainless Steel
Viton Seal
Million Cycle
Gate Valve

The Million Cycle Gate Valves Series are vacuum valves designed for high vacuum applications when pressure ranges approximate 1 x 10-9 mbar and bakeout temperatures do not exceed 150°C. There are no mechanical locks inside the vacuum, which is extremely beneficial for semiconductor and sensitive processes requiring vibration-free operation. All moving joints have hardened shafts, reducing particulate generation and providing smoother actuation. These valves provide valving for Cryopumps, Turbo Pumps, Ion Pumps, and other applications requiring clean, high cycle, low outgassing valves.

3-Position

The 3-Position Gate Valves are designed for use in etching, CVD, and any other process that requires pressure control. When used in conjunction with upstream mass flow controllers, this series valve has exceptional pressure control capability. The valves employ two pneumatic solenoids and an air pressure regulator to achieve three positions: fully-open, fully-closed, and an adjustable third position. The first solenoid controls the fully-open, fully-closed positions while a second solenoid controls the third position.
