Bettis PressureGuard Hydraulic Emergency Shutdown System
This hydraulic emergency shutdown system can perform valve shutdown with or without power. It is a self-contained hydraulic ESD system designed to provide reliable valve shut down on production wellheads.
The Bettis PressureGuard Hydraulic Emergency Shutdown (ESD) System is a fail-safe hydraulic control solution designed to ensure reliable valve closure during emergency situations, protecting personnel, equipment, and the environment. Developed by Emerson, this advanced hydraulic system provides rapid and dependable shutdown capability for critical process applications in oil and gas, pipeline, refining, and petrochemical industries. The PressureGuard system operates by maintaining stored hydraulic energy that can be automatically or manually triggered to close the valve in the event of a power failure, pressure loss, or emergency signal. Its self-contained design eliminates dependence on external power sources, ensuring fail-safe operation even in remote or unmanned installations. Engineered for integration with hydraulic actuators, including Bettis and Shafer models, the PressureGuard system delivers precise control, reliable performance, and quick response times. It features rugged construction, corrosion-resistant materials, and modular components that allow for easy installation, testing, and maintenance in demanding field environments. The Bettis PressureGuard system is widely used in pipeline block valve stations, wellhead control systems, and offshore production platforms, providing proven safety, reliability, and compliance with international ESD and SIL (Safety Integrity Level) standards.
