Delta Control Products Actuator Valve Assembly

D-53 Actuator

The D-53 Series is a direct-mount line of motor actuators that operates on 24 VAC power and is available for use with incremental or proportional controllers. These non-spring return actuators are easily installed on variable air volume (VAV) boxes as well as Bray SoftTouch Series characterized ball valves. The D-53 Series have a 53 lb-in (6 Nm) running torque. They have a nominal 90 second travel time for 90° of rotation at 60
Hz (108 seconds at 50 Hz).  The D-53 Series are available with integral auxiliary switches to perform switching functions at any angle within the selected rotation range. Proportional models feature 0 to 10 VDC position feedback.

Features:

• 35 dBA Rating
• 100,000-Cycle Rating
• Direct Shaft Mount with Single-screw Coupler
• Magnetic Clutch
• Jumper-selectable Rotation Direction on Proportional Models Simplifies installation
• Adjustable Rotation Stops
• 1/2 in. NPT Threaded Conduit Openings
• Manual Gear Release
• 0 to 10 VDC Feedback on Proportional Models

SoftTouch 2 Series Ball Valve

The Soft Touch 2 (ST2) series characterized ball valves provide accurate and cost effective control of a wide range of equipment in HVAC applications. The ST2 series features a forged brass 2-piece body with
Stainless Steel balls and stems for water temperature up to 284˚F (140˚C) and saturated steam up to 15 PSI. The Amodel® Flow Characterizing Disk maintains equal percentage Flow Characteristics for optimum
temperature control. The blowout-proof stem and mounting flange, combined with an innovative double O-Ring stem seal and self-centering stem bushing design provides quick and easy electric actuator field mounting while ensuring long life and leak-free valve performance. Graphite reinforced PTFE seats backed with EPDM O-rings significantly reduce operating torque, allowing the use of the most economical actuator to provide the torque required for the application.  All valve and actuator assemblies provide 200 psig (1,379 kPa) close-off pressure while ensuring operation after long idle periods. Because of their cost effective, reliable design, ST2 Series Ball Valves are maintenance free.

Features:

• 580 PSI (PN 40) Body Rating
• 200 PSI Close-off Rating
• ANSI Class IV (<.01%) Leakage
• Low Torque
• Greater than 500:1 Rangeability
