VSI Series 1000-X and 1000/S-X Electric Actuator use proven technology to provide reliable valve and damper automation. They are available in many control configurations including open/close service and modulating position control. With a deadband adjustable down to 0.5% and an 80% duty cycle modulating service, Series 1000-X and 1000/S-X actuators provide accurate dependable automation packages.

Implementations
The Series 1000-X actuator is designed to be the most robust, space efficient, and easy to install package possible. The compact enclosure minimizes interference problems common in modern piping and control rooms.

The actuator base conforms to international standards, and female drive allows the direct mounting on most valves without expensive and space hogging custom brackets.

The heavy die cast aluminum alloy housing with large cooling fins ensure a life span that will exceed that of most valves.

An Actuator For Every Application
With 8 unit sizes from 443inlbs all the way to 22,127inlbs the Series 1000-X is the perfect solution to most valve actuation applications or other automation such as dampers.

Everything from 1/4″ ball valves all the way to 24″ or larger butterfly valves can easily be automated with the Series 1000-X. The NEMA 4X housing can be used in control rooms or exposed to harsh sunlight and driving rain on building rooftops. Infrequently operated or typical isolation valves can use the economical open/close units while flow control applications operating at duty cycles of up to 80% are easily handled with the servo controlled modulating option.

Every application is different, and VSI or your authorized reseller are here to help you with an actuator to fit your needs. The Series 1000-X is available with simple options such as auxiliary limit switches all the way to project specific accommodations such as local controls, prewired cable connectors, battery backups, or special linkages for installations such as 3-way butterfly valves.

• NUMAR accessory mount.
• PTFE guide bar. Prevents yoke pin axial movement, transferring axial loads directly to the drive module case.
• Thrust Bearing. Connects the piston rod with the guide block, compensating for side load deflection and reducing wear on the rod, bearings and seals.
• Roller. Reduce the friction between the yoke arm and pin, minimizing the wear of the yoke arm and pin.
• PTFE guide ring. Prevents metal to metal contact with the cylinder bore.
• Replaceable Bearings. Protect sliding and rotating components, with suitability for either dry or lubricated working conditions.
• Integral Housing Vent. The main actuator housing incorporates and integral check valve in order to release over pressure.
• 80°~100° Travel Stops. Bi-directional travel stops that allow for 80°-100° total travel
