The ADR/EN Pneumatic Footvalve meets the requirements of an internal self-closing stop valve in accordance to 49CFR§178.345-11 and a non-pressure balanced footvalve in accordance to EN13308. It is designed for use with a wide variety of products and features a readily removable spring housing assembly and a pneumatic actuator that can be serviced without removing the valve from the tank.   The valve body is constructed of aluminum and features a shear section which meets break-away requirements of EN13308 and TTMA RP 84 per 49CFR§178.345-8.  A resilient Viton© B o-ring with a tapered seat provides positive sealing.  A heavy mounting flange is provided to insure a flat gasket surface, and a jack screw is included in the event of an air system failure.  The valve features an interlock system for sequential actuation of other components or indicator signals.  A stainless steel screen prevents objects in the tank from entering the piping. The Maximum Operating Pressure is defined as the maximum tank pressure that valve can open against w/ given air-line pressure.  Maximum Operating Pressure is 21 psi with 80 psi line pressure and 27 psi with 100 psi line pressure.  The Valve MAWP is 73 psi [5 bar] and the Minimum Shell Strength is 365 psi [25 bar].*
