The basic working principle is to use Pneumatic Air pressure to activate the operator on ISOV. In this configuration a 2/3 Way Solenoid Valve is used to release air pressure to ISOV. In addition to the Pneumatic Operator, each ISOV valve is equipped with a Manual Release Knob. ISOV Pneumatic Valves are widely used on gensets as well as marine and offshore engines. The Pneumatic version is available in sizes from 2" up to 20" (SO - 508 mm). Full Flow Overspeed Valve. Double spring action. Pneumatic, Electric, Failsafe and Manual Technical Data
The Pneumatic ISOV valve N200 is operated by applying Air or Oil pressure to the pneumatic cylinder integrated in the body. The Pressure inlet port is shown in the adjacent drawing. The pneumatic cylinder trips and closes ISOV when a pressure source is applied. The air or oil pressure is applied by using a 2/3 way solenoid valve as shown on the diagram. After tripping the pneumatic cylinder, ISOV will close and the 2/3 way solenoid has to be reset after which the valve can be opened and latched in the same manner as the Manual version. To increase safety, all ISOV pneumatic valves will be equipped with a manual Pull handle in case the solenoid for any reason may fail due to electric blackout. Standard Pressure inlet ports are 1/8 or 1/4 "size.
The Pneumatic ISOV valve N400 is operated by applying Air or Oil pressure to the pneumatic cylinder integrated in the body. The Pressure inlet port is shown in the adjacent drawing. The pneumatic cylinder trips and closes ISOV when a pressure source is applied. The air or oil pressure is applied by using a 2/3 way solenoid valve as shown on the diagram.
