SFPA Electro-Hydraulic Actuator - Bettis E Series
The SFPA electro-hydraulic system utilizes the Bettis hydraulic actuator powered by an SFPA power unit and controls. Efficient heavy-duty modular designed motor and pump convert electric power to hydraulic power. Self-contained in a highly efficient package with controls, provide the benefits of electric actuators, but with advantages for fail-safe action, modulation and high torques (from 3,000 - 6,000,000 lb. In. depending on models)

SFPA/Fenner/Shafer - Hydraulic Power Units
Our power units can meet many standards (CSA/UL including hazardous locations) and weather environments. SFP also builds controls and enclosures for both hydraulic and pneumatic valve automation applications.

 

Diaphram - GVO Series Linear Operator
Bettis GVO Series linear operators have been designed for service in safety shutdown and control applications. There are six basic models that address low pressure or high pressure operation and double-acting, spring-return or fail-safe configurations. Double-acting models are adaptable to any type of gate valve and have cylinder sizes ranging from 3 inches through 36 inches.

They come with optional jackscrew manual overrides and materials of construction for special applications. Spring-return models are adaptable to direct or reverse acting gate valves, API or ANSI and have cylinder sizes ranging from 8 inches through 36 inches. High pressure models are suitable for 2000 psig hydraulic service.

WellGuard Series Actuator
The WellGuardTM diaphragm range of pneumatic Control Fluid Powered linear actuators is designed to be used in conjunction with Bettis valve bonnets to provide open and close control for major brands of API 6A through conduit reverse acting gate valves fitted to oil and gas wellheads and production flow lines. These actuators can be used with API 6D and ANSI B16.34 valves where the bonnets are built to Bettis design.
 
Emergency Shutdown Systems
The PressureGuard(tm) Self-Contained Hydraulic Emergency Shutdown Systems are designed to provide reliable valve shutdown capability when an external power source is either not available or not dependable. The PressureGuard system has proven to be highly successful in years of field service under some of the most demanding operating and environmental conditions. The module can be used with either rotary or linear spring-return hydraulic operators to provide a fail-safe system adaptable to ball, plug and other quarter-turn valves as well as reverse-acting gate and other linear operated valves. The PressureGuard system offers built in temperature compensation and pressure relief. It provides the foundation for a flexible system utilizing a variety of available sensing and control options Bettis - PressureGuard
 
Gas/Hydraulic Operators and Control System
Gas/Hydraulic Valve Actuators (often referred to as Gas over Oil type) use a high pressure gas supply (typically 300 to 1480 psig) as their power source. Often used in gas/transmission pipelines in which the pipeline media is used for the actuator's power source. Actuators are available in rotary (1/4 - turn) and linear versions and can be supplied with practically any required control system including remote control and linebreak systems.
 
Electro-Hydraulic Operators and Control System
Our electro-hydraulic power units are manufactured using field proven
components and technology to satisfy the most rigorous applications.

Hydraulically powered double acting and spring return valve actuators are the primary application for this type of system. We offer central hydraulic systems designed to operate several valves from a single control center. Electro-hydraulic systems are designed to provide sufficient pressure and volume to stroke mutliple valves either singly or in unison, depending on the customer's requirements. Accumulators are also available to provide fail-safe and ESD functionality.
 
Multiport Flow Selector
The Bettis Multiport Flow Selector allows the diversion of fluids from a single flow line to a test outlet or a sampling device. A single Multiport Flow Selector can manifold as many as eight flow lines through it simultaneously. While the one outlet is isolated, the flow from the other seven is combined into a separate group outlet. This unique flow selector can be used in a variety of oil and gas or process applications.
 

Multiport Electronic Controller
The Bettis Multiport Electronic Controller (MEC) is a microprocessor - based system designed specifically to control and monitor the status of the MPFS. The MEC contains an absolute optical encoder allowing the monitoring of the plug's position to approximately 0.5°, retaining the memory of the position even without power. The controller card micro-processor analyzes input from the encoder and the host computer to accurately position the plug.
 
Quarter-Turn Electronic Controller
The Quarter Turn Electronic Controller (QEC) is a rugged optically encoded position controller suitable for on-off valve applications. It is a micro-controller based system which provides improved accuracy for position monitoring, eliminates problems associated with the mechanical adjustment of micro-switch cams and allows digital communication with multiple units over a single cable.
 

 

 

 

Linebreak Detection Systems:

LineGuard
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 and is designated to provide data acquisition and supervisory control (both locally and remotely through telemetry/SCADA) of a single valve actuator. The LineGuard 2100 guards your pipeline in three ways - rate of pressure drop (ROD), low pressure protection and high pressure protection. Further it records data for future analysis

DeltaMatic
The Bettis DeltaMatic(tm) linebreak detection system is designed to automatically monitor a gas pipeline and send an instrument pressure signal if a predetermined rate of pressure drop is exceeded. The system is typically used to detect a pipeline break situation and signal a valve operator. This automatic shutdown function provides safety and environmental protection in populated areas, river crossings, remote areas and other locations.

 

SP Pressure Pilot
The Pressurematic SP series pressure pilot is part of the Bettis line of pressure sensory devices used to monitor input pipeline or process pressure.
The pilot is suitable for use in high or low pressure shut down applications, utilizing either a pneumatic or hydraulic signal. Pilot set
points are determined by piston size and spring rate. A piston converts pressure into motion when a pre-determined set point is reached

PressureMatic High/Low Pressure Pilot
The Bettis Pressurematic line of pressure sensory devices are used to monitor pipeline or process pressure. They are suitable for use in high and low pressure shut down applications utilizing either a pneumatic or hydraulic signal. Set points are determined by piston size, spring rate and adjustments to the trip mechanism.
 
Isotest
Bettis Isolation test valve is used in conjunction with the SP and
Pressurematic sensing devices, and enables calibration of the pressure pilot/switch without shutting down the flow line.
 
Relays and General Control Components
Bettis Switching Relays are pneumatic/hydraulic poppet style switching devices - manual or pilot operated - for use with high or low pressure control applications. In pneumatic service, they can operate with high pressure gas to 1500 psig, or to 150 psig in low pressure service. The switching relays are also available as hydraulic models, operating to a maximum of 2160 psig. The Bettis relays are available as 3-way and 4-way 2-position bodies with a range of switching options including pneumatic or hydraulic pilot, mechanical and manual lever
