    • All ISOV E Valves are closed by activating a linear 12 or 24 VDC solenoid. The Solenoid Valve generates a large Pull force to release the internal tripping mechanism. Unlike other suppliers of safety valves, ISOV mounted solenoids are equipped with an IP65 rated junctionbox to guarantee safe and reliable wiring. In addition to this, all E versions are equipped with the Manual Pull Handle to close safely in case electric power is lost.

    • ISOV Failsafe Valves are often used on offshore cranes as well as on Oil and Gas installations whereby the valve has to close whenever electric power is lost. The FS version requires Oil or Air pressure to guarantee its functionality. The basic working principle is that Pressure holds the valve open by energizing a 2/3 way Normally Closed solenoid valve. When power is lost the solenoid creates loss of pressure causing ISOV to trip and close.

    • 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).

    • 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 ISOV valve is a positive spring operated air intake shutoff valve that provides emergency overspeed shutdown of a diesel engine. Mechanical failure or the presence of combustible vapors like hydrocarbons in the engine’s intake system may cause the engine to overspeed beyond control, causing severe damage to the engine or even explosion.
We offer the most comprehensive and diverse line of positive air shutoff valves.
In addition, our installation and activation kits are specifically engineered for your application.
