SY Series: Small Steel Scotch Yoke Actuator
SYSSSYA
Steel for Outstanding Corrosion Protection Pneumatic Actuators for Quarter-Turn Valves and Dampers Torques from 800 - 12,370 In-lbs. Double Acting Spring Return TRIAC® SY Series scotch yoke actuators by A-T Controls offer “workhorse” cycle operation. These rugged multi-purpose actuators are the compliment to the already trusted THD Series. The compact design offers options to address your quarter turn torque requirements. The SY Series is a reliable way to automate quarter turn valves and provides options for accessory mounting and manual override operation. The design is modular and allows for easy rotation choices. Simply flip the actuator to achieve clockwise (CW) or counterclockwise (CCW) operation. This design features a supported scotch yoke which is stabilized by significant body bearings for minimal wear. Various spring and pressure options allow you to achieve the torque balance you need. Increased efficiencies in this design give you the most actuator for the money. For many applications, steel is just better. These small steel scotch yoke actuators, compared to aluminum, provide better corrosion resistance in harsh environments such as marine salt water and petro-chemical applications. Additionally, surface coatings adhere better than aluminum. When your application calls for rugged and reliable valve actuation, rely on the TRIAC® SY Series

TA-Luft: Low Emissions Ball Valves
TALuftLEBV
In March of 2007 A-T Controls received TA-Luft Low Emission certification for broad range of valves with a patented Pyramidal Stem Seal system. At that time fourteen different TRIAC series valves with the live-loaded packing system passed the TA-Luft standard that was established by the German TUV agency (Technischer Uberwachungs-Verein). Considered the world's most stringent standard on valve emissions, TU-Luft testing requires less than 1 ppm leakage through the valve stem. Fugitive valve emissions are a major environmental and economic issue for process industries. TRIAC valves can reduce fugitive emissions and lost product by 99% or more compared to legacy control valves. A-T is excited to offer such a range of valve choices to help industries in their drives to reduce emissions. The TRIAC TA-Luft certified valves employ a unique live-loaded pyramidal stem packing system. This features a patented 45° pyramidal stem and stem seal with Belleville washers and PTFE chevron style stem packing, protecting against stem leaks experienced with ordinary ball valves. The TRIAC valves also feature a patented automation pad that allows direct mounting of ISO5211-compliant actuators to eliminate the cost and fabrication of special couplings or brackets. A-T Control's product literature identifies each valve model carrying the TA-Luft certification with a green logo.

Three Position Dribble Control
TPDC
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.

TRIAC® Floor Mounted Damper Drives Available in Pneumatic or Electric Configurations
TriacFMDD
TRIAC® floor mounted damper drives are the best choice for operating dampers, vanes and fan control where high vibration, heat, extreme cold, dust and inaccessibility render direct coupling of actuators to shafts impractical. Available in pneumatic (on-off and modulating), and electric (24 VDC, 120 VAC 1-phase, 220 and 440 volt 3-phase configurations, these rugged drives combine industry proven TRIAC® pneumatic and electric actuators with our engineering expertise. The rugged frames can be ordered to dimensionally replace older drives manufactured by several previous suppliers. TRIAC® frames consist of welded steel housings with pillow block bearings, maintenance access panels, and our unique infinite position lever arms. The units are tough enough for the harshest environments found in today’s refineries, power plants, steel-making boiler rooms, water treatment facilities, pollution controls, pulp and paper industries and co-generation turbine units. Contact A-T Controls for specific drawings and specifications for your replacement or new applications.

V Series: Full V-Port Control Valves
VFVPCV
Triac® V-Port Control Valves are ideal for achieving more precise control with the simplicity and sealing features of a ball valve. The V-port valves are available with 15°, 30°, 60°, and 90° V-notch options (custom cut also available). V-port valves offer better and more consistent control than traditional round ported ball valves. We offer this valve with the control port cast and machined into the ball, not in the seat, which allows for much better flow characteristics and eliminates the need to replace seats. The 15° and 30° options allow for finer tapered control throughout the valve rotation, and the 60° and 90° offer a larger Cv in addition to controlled flow. The PTFE seat is standard in the V7 valves, while the 50/50 STFE seat is standard with V8, V9, and FVD9 V-port valves. The 50% 316 SST powder and 50% PTFE offers both strength and superior sealing properties. While they are available as manual ball valves, we specialize in automating them to suit your particular control requirements. Features Sizes 1/2”-4”, 3-Piece (V7, V8) Sizes 1/2”-6”, 150# Flanged (V9) Sizes 1/2”-6”, 300# Flanged Firesafe (FVD9) 316SST or WCB TA-Luft Certifed Low Emissions (V8, V9) 15°, 30°, 60° and 90° “V” Notch Standard (Others on request) See product catalog for detailed product information.
