Operation

The Rigsaver air intake shutoff valve is a swing-gate, spring-operated air shut-off device mounted in the air intake system. It will impede the airflow into the cylinders and positively stop the engine. It can be installed pre- or post-turbo. The Rigsaver shutoff valve can be manually or automatically controlled to respond to a variety of fault or hazard conditions.

Tripping options

Manual/pull cable: This is the simplest method. The gate is released by pulling on a handle or cable attached to the tip spindle.

Manual/pneumatic: The trip is retracted by an integrated pneumatic cylinder. A manually-operated three-way valve directs air pressure to release the trip spindle. The pneumatic trip cylinder may also be tripped manually by pulling on a handle or cable attached to the trip spindle.

Electric: The trip is retracted by a 12 volt or 24 volt electric solenoid which is controlled by an automatic overspeed sensor and associated valving. The pneumatic trip cylinder may also be tripped manually by pulling on a handle or cable attached to the tip spindle.

Pneumatic: The trip spindle is retracted by a pneumatic cylinder. The trip cylinder is controlled by an automatic overspeed sensor and associated valving. The pneumatic trip cylinder may also be tripped manually by pulling on a handle or cable attached to the tip spindle.
