71000 Series Long Life Harsh Process Gate Valves
Introduction

Product Features- Extreme durability for the most demanding processes- Robust dual containment design and low particles- > 250,000 cycles- HV with machined stainless steel billet body- Sizes from 2” ID (DN50) to 8” ID (DN200)- Manual and pneumatic actuation

71000- Stainless steel welded bellows outside of process- Standard KF, ISO, CF, ANSI, JIS or custom flange options- High temperature options up to 250°C
Model Number 71210-0403R4” ID (DN100) Pneumatic ISO-F- Easily customizable to work with almost any application- Designed, manufactured and assembled in the USA

Description
The 71000 Series Gate Valves are machined out of solid stainless steel billet and feature a simple dual
containment design at the gate that seals on both sides. There are very few moving parts, so the valves have
low particle generation. With virtually no moving parts in the gate mechanism the movement is not affected bydirty processes that would normally interfere with a standard mechanical gate. The bellows is outside of process, and is protected by a wiper ring. The body and all major internal components are vacuum furnace brazed
at 1100°C, at 1x10-6 mbar, ensuring maximum joint integrity. This eliminates the possibility of virtual leaks orentrapment areas and minimizes body distortion found in conventionally welded valves. For maintenance purposes, the carriage assembly can easily be removed from the body without removing the valve from 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 1x10-9 mbar and bakeout temperatures do not exceed
250°C. These valves provide valving for anything needing vacuum in a dirty or harsh environment. They can becustomized to work with almost any application.

Internally Heated and Water-Cooled
These valves can easily be fitted with heaters to internally heat a process from the inside up to 250°C. See custom
internally heated valve section on page 187. They can also be used to cool process internally via the gate and theflanges.

Position Indicator: R = Reed Switch / M = Microswitch /P = Reed switch w/6-pin / V = Visual
