Safety Valves are used to protect the tank from over-pressure in
the event of an accident involving a fire. McKenzie Valve
supplies both low-flow and high-flow capacity designs generally
used for non-insulated non-pressure tank cars. The valve is
available with either a 75 psi or a 165 psi start-to-discharge
pressure.
The low-flow valve mounts on a standard 3-1/2” nozzle using (4)
3/4"-10 bolts on a 6-1/4” bolt circle as prescribed by AAR Fig
E-21. The valves are constructed of either carbon steel or
stainless steel with a stainless trim.
The high-flow valve mounts on a standard 6-1/2” nozzle using (8)
5/8”-11 bolts on a 10-1/4” bolt circle as prescribed by AAR Fig
E-11. The valve is constructed of carbon steel with a stainless
steel trim. Carbon steel components are fully plated for maximum
corrosion protection.
The safety valves are available with the standard O-ring material
options that are color coded and available at the base price.
Alternate O-ring materials are also available as a special order.
They will be supplied black unless otherwise specified.
