ISOV emergency shutoff valves prevent engine overspeeding by shutting off the air intake line.
Prior to starting the engine the manual ISOV emergency valve must be latched open by rotating the manual reset axis. One latched the reset lever will remain in the latched open position until released by pulling the manual trip handle.
The manual trip handle can be mounted directly on the valve or mounted remotely using a special kit which includes a pull cable, available in different lengths.
The remote manual pull handle is usually found on mobile equipment, trucks etc.
The manual pull handle can be equipped on all ISOV valves, regardless of size.
