EXPLOSION ISOLATION VALVE
INSTALLATION & OPERATION MANUAL
January, 2015 Document P/N: E06-017-1 (Rev 2) Page: 1
INTRODUCTION
This manual is intended to provide installers with comprehensive information pertaining to the installation of Fike
Explosion Isolation Valves. This information should be used in conjunction with the field installation drawings
provided for the specific application.
1.0 GENERAL INFORMATION
1.1 DESCRIPTION
The Fike Explosion Isolation Valve (EIV) is used in conjunction with other Fike Explosion Protection System
components to prevent the propagation of a flame front through ducts or conveying lines to additional equipment
or occupied areas. The Fike EIV provides a positive mechanical seal in process piping or ducts when activated
by the system controller. The Fike EIV has a stainless steel full ported conduit gate. The pipe flanges fit ANSI
150 bolting. The modular construction of the Fike EIV allows on-site refurbishment and/or rebuilding; typically
without removing the valve from the process piping.
The principal function of the EIV is to rapidly close the pipe or duct to prevent further travel of the deflagration
flame front. Valve closure is initiated when the system controller sends an activation signal to an electrically
actuated cartridge device. This cartridge device generates a high volume, instantaneous pressure that moves a
pneumatic piston connected to the gate. This closed gate seals off the pipe or duct preventing the passage of
flame to other equipment or personnel occupied areas.

WARNING: The GCA shall not be installed until the EIV and control system are installed and checked for
proper operation.
WARNING: The GCA shall only be installed by Fike certified personnel.
WARNING: To prevent possible injury, the GCA shall be disconnected and shunted prior to performing
maintenance on the EIV.
WARNING: When performing maintenance on the valve which exposes internal components, the lockout pin
shall be secured to prevent accidental movement of the gate, piston and piston rod.
