2. Install the 9400 series in a vertical position so the valve body is self-

draining. The inlet piping should be short as possible, with no elbows,

and equal to or greater than the size of the pressure relief valve inlet

connection.

3. The discharge piping should be equal to or greater than the size of the

pressure relief valve outlet connection so as to prevent backpressure

when relieving. The piping termination point must be in a safe location

and away from ignition sources. The termination point must be

positioned to prevent the accumulation of moisture. An appropriate

load-bearing device should support discharge piping, other than a

short tailpipe.

MAINTENANCE

The relief valve should be inspected every 12-18 months to ensure proper

working order. Depending on the service and the condition of the valve, the

inspection interval may be adjusted.
