Rigsaver

Rigsaver shut off valve

Rigsaver valves can be manually or automatically controlled to help prevent diesel engine over speed by cutting off the air supply to the engine. Rigsaver is an ISO 9001:2008 certified swing gate, spring-operated air shutoff device mounted in the air intake system that stops the airflow into the cylinders and positively immobilises the engine, safeguarding personnel and equipment. It can be manually or automatically controlled, responding to a variety of fault or hazard conditions.

Upgrade your legacy 11SGE shut off valve to the next generation, and extend the life of your valve by introducing the recommended maintenance schedule (see below).

Legacy 11SGE (11 inch) shut off valves (manufactured before January 1, 2014) are highly recommended to be upgraded. After extended periods of vibration, the valve may require higher air pressure to activate or may have a tendency to false trip. The issue may worsen if the regular maintenance schedule is not maintained. It is recommended the user verifies performance with regular cycle testing and adheres to the maintenance schedule (see below).

Benefits of upgrading the valve include:

  • Higher durability and vibration resistance
  • Reduces the required activation pressure to improve reliability
  • High quality O-ring seals for better serviceability
  • Eliminates charge air leakage
  • Larger manual action handle allows user to actuate valve with twist action
  • Optimizes components for serviceability

Maintenance Schedule

An important part of optimising the performance of your Rigsaver air shutoff valve is maintaining a regular service schedule. For legacy-style 11” SGE RIGSAVER valves, first upgrade with a cover kit to ensure your equipment is protected by the latest design. Next, utilise the service schedule to extend the useful life of your valve. For next generation Rigsaver 11” SGE valves, it is strongly recommended to replace older parts with genuine Rigsaver parts according to the maintenance schedule.
