An Isolator Valve Key Tool allows controlled operation of isolator valves during diagnostic and testing procedures. The tool engages square valve interfaces to apply a steady turning force without sudden movement. Controlled valve actuation helps generate specific pressure and temperature conditions needed for accurate testing. This controlled operation supports the reliable evaluation of sensors and switches. The tool allows technicians to adjust conditions gradually during testing tasks.Attributes:• Enables gradual valve movement to control test conditions.• Helps apply a steady turning force to square valve interfaces.• Allows proper adjustment of valve positions during tests.Applications: An Isolator Valve Key Tool is used at isolator valves during testing, where it operates the valve to generate controlled pressure and temperature conditions for checking sensors and switches.
