3. Mating line flanges must be properly
aligned. Slip-on or weld flanges can be used.
Never try to make up for misaligned pipe
flanges by the line bolting.
4. Flange fasteners should be tightened in a
uniform manner using a cross-pattern to
prevent distortion of the valve.
5. Pipe supports and/or expansion joints should
be used to minimize pipe loads on valves.
ZP300 valves are suitable for use in either
vertical or horizontal lines. If installation is
other than vertical, additional support will be
required for cylinder actuated valves.
