81000 Series Aluminum Gate Valves
Introduction

Product Features- Body is precision machined from aluminum 6061-T6 billet- 250,000 to 400,000 cycles- Sizes from 1.5” ID (DN40) to 12” ID (DN300)- Manual and pneumatic actuation- Unique dual quad ring long life shaft seals- Standard KF, ISO, CF, ANSI, JIS or custom flange options- Easily customizable to work with almost any application

81000- Designed, manufactured and assembled in the USA

Model Number 81110-0403
4” ID (DN100) Manual ISO-FDescription
The 81000 Series Aluminum Gate Valves feature dual quad ring shaft seals for long life and improved leak integrity.
High performance PEEK® is used on high cycle internal components to reduce friction and lower particle levels. The
body and all major internal components are precision machined out of solid 6061-T6 aluminum billet. This eliminates
pinhole and virtual leaks that are common in cast or welded aluminum bodies. The valve is also direct drive and uses
a large diameter driveshaft for reduced vibration. For maintenance purposes, the body is split above the flange forminimal clearance when removing the internal parts for servicing, while the lower portion can remain on the system.

Applications
KF Flanges, ISO Bolted and Clamped Flanges, ANSI and optional JIS Models are designed for high vacuum
applications specifically when pressure ranges approximate 1x10-7 mbar and bakeout temperatures do not exceed
150°C. They can be customized to work with almost any application.

ANSI, JIS & Custom Flanges
ANSI Flange Models
ANSI Flange Models are designed for high vacuum applications, specifically when pressure ranges approximate 1x10-9
mbar and bakeout temperatures do not exceed 200ºC. The
bonnet comes standard with a Viton® elastomer O-ring.
These valves provide valving for cryopumps, turbomolecularpumps, ion pumps and other applications requiring clean,
low outgassing valves. Pneumatic valves are supplied with a120 VAC solenoid and a Reed switch position indicator.
Standard flanges are smooth faced, non-rotatable
and threaded. When O-ring grooves are required onflanges, please specify one of the following options:• O-ring groove on gate side only
• O-ring groove on carriage side only
• O-ring grooves on both gate side and carriage side
O-ring groove I.D. is 0.250-inch larger than the valve I.D.
Flange O-rings are not included with the valve, and may bepurchased separately.

81000

JIS and Custom Flange Models
Valves requiring JIS flanges may be obtained through HVA(see page 195). Additionally, other specialty flanges fornon-standard installations may be custom ordered throughHVA. Contact HVA Technical Services to discuss yourrequirements.
