Low-Pressure Pneumatic

This is a highly unique and reliable actuator for operating ball, butterfly or plug valves which are quarter turn style. Suitable for use in demanding SIL-required applications.

Our pneumatic actuators include rack-and-pinion and scotch yoke designs.

Scotch yoke design creates high break-out torques, hence suitable for quarter-turn valves up to the largest sizes. Double acting and spring return gas actuators for remote and local operation of valves in on-off and modulating heavy-duty service.

Features

  • Consistently operates in challenging environments, hostile environments, and when power is challenged
  • Modular design improves efficiency reduces wear extends life
  • Tension-Lok™ device positively locks the spring module to allow its safe removal and installation, eliminating accidental release of the spring force
  • PED 2014/68/EU compliant to meet the stringent requirements of pressure mounting vessels
  • Meets both IP66 and IP67M specifications for submergence and high pressure water deluge test and offers superior water ingress and corrosion protection
  • Offers multiple configurations, with a modular design that enables safe field maintenance and reduced inventory costs
  • Interchangeable power and spring modules for quick reversal of the fail-safe mode

Rack-and-pinion actuators

Provides the most economical on-off and modulating control for small to medium quarter-turn valves. available in 12 sizes as spring return or double-acting models. The actuators have a tough and reliable design and are intended to operate quarter-turn valves or any other quarter-turn application. This actuator comes with coated body and endcaps, has a special high corrosion-resistant aluminum pinion design, and has stainless steel fasteners, resulting in a long-lasting, durable actuator design.

Features

  • Heavy duty body castings provide maximum protection in the harsh environment of process plant locations.
  • Polyurethane powder coating provides excellent corrosion resistance on housing and end caps.
  • One piece blow-out proof, pressure balanced, pinion allows safe in-field re-configuration from Fail-Close to Fail-Open.
  • Precision dual stroke adjustment provides accurate and intuitive end of stroke adjustment for the Open and Closed valve position.
  • Low maintenance bearings for pistons and pinion.
  • Accurately designed and machined components assure a perfect fit and long cycle life.
  • Stainless steel or Deltatone™ coated fasteners.
  • VDI/VDE 3845 (NAMUR) solenoid interface and top accessory interface.
  • Dual ISO 5211 mounting patterns allow low-profile direct mounting to valves.
  • Drive inserts on the valve flange make direct mounting flexible, either for square, flat head, or round with key way stems.

Electro-hydraulic

Our Standard Electro-Hydraulic Operator(EHO) is a self-contained electro-hydraulic actuator designed to actuate quarter-turn valves. It is designed to provide fail-safe actuation for Emergency Shut Down(ESD) valves. The Bettis Standard EHO provides a straight forward, simple, reliable ESD actuator solution.

Features

  • Utilizes a dependable spring-return actuator for the fail-safe stroke combined with an integral hydraulic power pack and electronic control module
  • Designed as an emergency shutdown actuation solution to stop process flow upon the detection of a command signal or loss of power, protecting personnel, equipment, and the environment
  • Consistently operates in challenging environments, hostile environments, and when power is challenged
  • Over fifteen alerts and alarms to help alert users of abnormalities in the system
  • Can be integrated into systems with existing common communication protocols and DCMLink
  • Communication Protocols- HART and FOUNDATION Fieldbus, DCMlink configuration and monitoring software compatibility
  • Environmental Protection: Control enclosure: IP68, Hydraulic actuator: IP67M, Motor: IP68

Double Speed and Standard Gears

High-performance manual valve operators feature autolock technology that enables high-performance worm-gear solutions with the self-locking characteristics of conventional gearboxes. As a result, less work is required for valve operation.

Features

  • Self-locking design
  • Up to 75% less work required
  • Enhanced worker efficiency on manual valves, reduced need for actuators, and smaller actuators on motorized valves
  • Improved HSE profile
  • Quick stroke times when required
  • Double-enveloping gear set
  • Unique tooth form to reduce microscopic stresses
  • Superior sealing system and IP68 ingress protection rating
  • Rigorous testing and qualification
  • Best-in-class construction materials, including bronze output bearings to prevent galling
  • ATEX certification
  • Compliance with American Water Works Association (AWWA), US military (MIL) specifications, and ISO 9001:2000
  • Manufactured in the USA
