Hydraulic valve actuator GH

linearrotaryquarter-turn

Product Description
The Bettis-GH Series is a high-pressure scotch yoke hydraulic valve actuator designed to automate valves on gas transmission pipelines where pneumatic or centralized hydraulic supplies are not available. It is engineered for remote and harsh-field installations to provide reliable quarter-turn and linear actuation for large-scale pipeline control.

Key Features

• Operates high-pressure natural gas pipelines in remote locations and under severe climatic conditions
• Zero-leak pistons and rod seals with materials selected for each application
• Multiple control system options including remote control, high/low shutoff and line-break protection
• Five-year material and workmanship warranty
• Converts linear motion to rotary motion (scotch yoke) with breakaway torques from 5,000 lb‑in (565 Nm) to 6,000,000 lb‑in (678,000 Nm)
• Standard lightweight cast aluminum drive case; optional ductile iron or cast steel cases available
