AIR VOLUME BOOSTER

AVB-3000

Introduction

The AVB-3000 series is the heavy-duty volume booster relays with bigger ports and a more flow capacity to help a large actuator move faster by converting a low flow control signal to the higher flow

AVB - 3000

AVB - 3100

Features

  • Delivers a high air volume for a fast actuator movement

  • Tunes a unit response to eliminate an actuator overshoot or overdamping

  • Provides a tight shut off to reduce a costly air consumption

  • Available in aluminum or stainless steel 316

  • Exhaust filters are installed for prevention of contamination by foreign substances from outside

Options

  • NPT 1/2 threaded exhaust ports

  • Supply pressure gauge port

  • High temperature: -20°C – +120°C

  • Low temperature: -40°C – +80°C
