Air Volume Boosters

Air Volume Boosters

AVB

The AVB Series is an air volume booster that is mounted between the positioner and actuator. It provides the actuator with a high air flow output, whose pressure corresponds exactly to the signal pressure. Delivers high air volume to actuator Provides ample air volume flow between positioner and actuator to eliminate over and/or under travel of the control signal Provides a tight shut off to reduce a costly air consumption Exhaust filters are installed for prevention of contamination by foreign substances from outside

Block and Bleed Valve

Block and Bleed Valve

BBV

The Block and Bleed Valve (BBV) is a NAMUR mounted module for the actuator. The BBV is used as a bypass valve for use with a manual override to shut off supply air and vent actuator ports. The BBV may also be used as a lockout valve which when properly implemented, will satisfy OSHA Standard 1910.147, “The Control of Hazardous Energy.”

Declutchable Gear Override

Declutchable Gear Override

DeclutchableGO

The Declutchable Gear Override “Sandwich Mounts” between a pneumatic quarter-turn actuator and a ball, butterfly, plug or damper valve. This rugged device allows for manual operation during installation, system testing and in the event of an air supply failure. The DGO Series mounts directly to many of the most popular rack and pinion style actuators on the market, and does not require a bracket between the pneumatic actuator and declutchable override. The units come complete with a three-stage coupler that connects to the pneumatic actuator through the gear override and to the valve (or coupler). Output torques cover a broad range of pneumatic actuator and quarter-turn valve sizes that require the convenience of a manual override. FEATURES: There are 2 Industry Standard Mounting Patterns: 3RDGO – Matches the ISO 5211 dimensions 3KDGO – Matches the Keystone 3.25 and 5.00 bolt patterns 3 Stage Coupler (Actuator, Gear, Valve) Rugged Declutch Lever and Engagement Handle BBV – Block and Bleed Valve to exhaust air supply from actuator
