Approvals

Features

• The on-off accelerator is a pilot accessory that increases the speed of hydraulic control valve operation by providing a large-volume rapid flow path in the pilot circuit during the opening or closing stroke
• Used on slow-acting control valves where faster response is needed, while still maintaining controllable stroke rates to prevent water hammer
• The adjustable orifice allows stroke rate to be tuned to the specific installation

Description

The on-off accelerator is a pilot accessory that increases the speed of hydraulic control valve operation by providing a large-volume rapid flow path in the pilot circuit during the opening or closing stroke. Used on slow-acting control valves where faster response is needed, while still maintaining controllable stroke rates to prevent water hammer. The adjustable orifice allows stroke rate to be tuned to the specific installation.
