Manual Override Gear Operators
Hydraulic Power Units (HPU)

Switches/Switchboxes/Controllers

El-O-Matic
Make the actuator operate faster or slower, provide position signaling feedback to the controller, or to provide positional control.

Hytork
Switch Enclosures and Position Indicators, Positioners, Accessory Mounting Brackets, Test System for Actuated Emergency Shut Down Valves, and Manual Override

Bettis
Multi-Port Flow Selector Controllers - A microprocessor-based system designed specifically to control and monitor the status of the Multiport Flow Selectors.

Topworx
Valve Controllers, Monitors and Position Sensors - Like no other product of its kind, the Topworx Lumitech line is the world's first direct mount valve controller, monitor or position sensor. Lumitech leads the way in performance and value.

Rotary & Linear Valve Position Monitors - Go Switchpak Rotary valve position monitors that combine position sensors, visual position indication, and terminations in an enclosure that eliminates junction boxes and conduit. Linear valve position monitors combine position sensors and terminations in an explosion proof enclosure and require no linkages or couplers for mounting.

Go Switch Leverless Limit Switches - Industry leader Topworx Switches stands alone in our industry for one main reason: they operate by magnetism. What does that mean? Our switches have no levers or arms to break or jam. Even better, our switches perform hundreds of millions of cycles uninterrupted regardless of what type of harsh environment they’re placed in.

Linebreak Systems

Bettis
A self-contained pneumatic pipeline monitoring and line break detection device intended to be installed at a pipeline valve site. Designated to guard your pipeline in three ways - rate of pressure drop, low pressure protection, and high pressure protection.

The LineGuard 2100 Electronic Linebreak Detection System is a self-contained pipeline monitoring and linebreak detection device intended to be installed at a pipeline valve site. Designated to guard your pipeline in three ways - rate of pressure drop, low pressure protection, and high pressure protection.

Other (Bettis Pressure Pilot & Topworx Smart Tag)

Bettis Pressure Pilot
Pressure Pilot Valves by Bettis - Used to monitor pipeline or process pressure. Suitable for high and low pressure shut down applications utilizing either a pneumatic or hydraulic signal.

Topworx
Smart Tag - Valve Identification System - This paperless valve I.D. system isn’t like ordinary metal I.D. tags. It maintains important valve maintenance and performance data records and can be used on all valve equipment. Each Smart Tag has 64K of memory, an ISA 20.50 Data Sheet and Read/Write maintenance files.
