GHGHL-1

IntroductionPaladon’s GH and GHL-Series use high pressure process gas to provide the energy required to power the actuator. To provide increased safety and reliability, the process gas acts upon hydraulic fl uid stored in gas/hydraulic tanks, creating hydraulic pressure that is subsequently used to power the actuator. As standard, the gas-over-oil control system provides local open and close control using either the high pressure process gas, or via a hydraulic hand pump. Numerous additional control system options are available; including remote control and linebreak detection (high/low and rate-of-drop) . Although gas-over-oil actuators and control systems are more complicated than direct gas type actuators, they offer many benefi ts including increased safety, reliability and operational lifespan.

Additional ProductslPN & HY-Series Scotch-Yoke Actuators

PN & HY-Series actuators are high performance pneumatic and hydraulic scotch-yoke actuators designed to operate any quarter-turn mechanism in both double-acting and spring-return configurations.

lPNL & HYL-Series Linear Actuators PNL & HYL-Series are high performance pneumatic and hydraulic actuators designed to operate any linear valve or mechanism in both double-acting and spring-return configurations.

lElectro-Hydraulic Control Systems These systems use electric pumps to pressurize hydraulic accumulators to provide hydraulic power. Stand-alone units using solar panels are also available when local utilities are unavailable or unreliable.

lElectro Hydraulic Positional Control Systems Suitable for both Choke and Control Valve applications, operating from either existing ring main or self-contained power sources. Available for both Offshore Hazardous locations and Industrial Power Generation

lDG-Series Direct Gas Actuators DG-Series actuators are typically used in gas pipeline applications in which the pipeline gas is used directly to power the actuators.

lSubsea Actuators The rugged and flexible design does not require pressure compensation for depths down to 650 ft (200m). For deeper applications, a pressure compensated design is available for depths down to 6,500 ft (2,000m).

lAutonomous Shutdown Valve (ASV) The ASV is designed to provide full automatic fail-safe operation of subsea valves to isolate pipelines from flexible risers.
