VA7800 Valve Actuator

VA7800 Series Electric Valve Actuators

Code No. LIT-1900558 Issued June 4, 2015

Description

The VA7800 Series of electric valve actuators control VG7000 Series Bronze Globe Valves in HVAC systems. The VA7800 Series produce a minimum linear output force of 180 lb (800 N) and are ordered field mounted or factory coupled to 1/2 through 2 in. VG7000 Series Bronze Globe Valves. All actuators are direct mount and available in both spring-return and non-spring-return models.

Spring-return models ship from the factory set for DC 0 to 10 V Proportional Control. With a change of DIP switch settings, this model can be field configured to On/Off or Floating Control. In addition to these settings, optional auxiliary switches are also available.

Non-spring-return models are available in AC 24 V On/Off (Floating) Control, or DC 0 to 10 V Proportional Control. Models are available with or without optional auxiliary switches.

Refer to the VA7800 Series Electric Valve Actuators Product Bulletin (LIT-12011474) for

important product application information.

Features

• Automatic Stroke Adjustment — provides easy, quick, and precise commissioning.

• Manual Override as Standard — allows manual positioning of valve for easy commissioning and servicing.

• IP54 Enclosure Protection — allows installation in a wide range of environments.

• Unique Swing-Gate Yoke — offers fast and secure attachment to the valve.

• Brushless Motor — ensures low energy consumption and long life.

• Proportional Model — enables one model to be used for various control types.

• Force-Controlled Motor Shutoff — reduces energy consumption, wear of the actuator, and protects the valve from excessive forces.

• Stroke Position Indicator — gives visual indication of valve operation, provides automatic adjustment of stroke indicators during first cycle of operation.

• Status Light-Emitting Diode (LED) — gives visual indication of actuator status and assists with diagnostic.

• Optional Integrated Auxiliary Switches — provides adjustable switch points with line voltage capability.

• Integral Cable with Colored Conductors — simplifies installation and field wiring.

• Integral Connector for 3/8 in. (10mm) Flexible Metal Conduit (FMC) — simplifies installation and field wiring.

• Underwriters Laboratories Inc.® (UL) and CE Compliant — provides internationally recognized regulatory agency approval.
