Air Volume Boosters
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
The Block & 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.”

Filter Regulator
- Stable setting pressure: Constant output pressure under variable flow rates or supply pressures.
- Corrosion-resistant construction: Aluminum die-casting are finished with chromate.
- Filter: It is designed to equip with high capacity 5 Micron Filter housed.
- Self Relief function: Self-Relief function is operated when the output pressure is higher than setting pressure.
- High flow capacity: It is designed to supply sufficient flow.
- Disc: It is strong in oil resistance.
- Tight shut off: A soft, rubberized pin provides a positive shut off and compensates for dirt and other foreign matter.

Lock-up Valve
A-T Controls' Lock-up Valve is an excellent choice for all fail-in-place applications when air supply drops below acceptable pressure. The LV-1 can be utilized to maintain valve or damper position when properly connected to Triac® Pneumatic Actuators.

Three Position Dribble Control
The Triac® Dribble Control package is a complete unit incorporating two integral solenoid valves within a specifically configured limit switch designed for dribble control. The dribble control package mounts directly to all Triac® pneumatic actuators without additional mounting hardware.
Common Applications:
- Filling or metering vessels - By being able to reduce the flow rate at a given point during a filling operation. It is possible to more accurately and efficiently fill a vessel.
- Flow dampening - With the dribble control package, automated valves can be partially closed rapidly and then completely closed gradually. This dramatically reduces shock to pipes and valves.

Valve Position Dome Indicators
- Rugged Polycarbonate construction
- Provides clear indication of valve/actuator indicator status
- Mounts directly to actuators that have NAMUR interface
