Horizontal tanks are exempt from the OPD Law and the old valves are fine
I can't seem to find what the old code says so they must have changed it in the newer codes to date,
2-3.1.5 Cylinders with 4 lb (1.8 kg) through 40 lb (18 kg) propane
capacity for vapor service shall comply with the following:
(a) * Cylinders fabricated after September 30, 1998, shall
be equipped or fitted with a listed overfilling prevention
device and a fixed maximum liquid level gauge. These
devices shall be part of the container assembly. The length of
the fixed maximum liquid level gauge dip tube shall be in
accordance with 4-4.3.3(a).
(b) Cylinders requalified after September 30, 1998, shall
be equipped with an overfilling prevention device and a fixed
maximum liquid level gauge prior to being filled.
(c) Effective April 1, 2002, no cylinder shall be filled
unless it is equipped with an overfilling prevention device
and a fixed maximum liquid level gauge. The length of the
fixed maximum liquid level gauge dip tube shall be in accordance
with 4-4.3.3(a).
