1116FM (Angle) - Pressure Relief Valve
Installation and Start-up
Start-up of an Automatic Control Valve requires following proper procedures. Time must be allowed for the valve to react
to adjustments and the system to stabilize. The objective is to bring the valve into service in a controlled manner to protect
the system from damaging overpressure.
NOTICE: Avoid mounting valves in a vertical discharge postion (valve stem horizontal or cover pointed sideways.) Valves mounted in
this position may not perform as tested and approved.
• Clear the line of slag and other debris.
• Install the valve so that the FLOW ARROW marked on the valve body matches the flow through the line.
• Install pressure gauge (supplied) in the fitting on valve tubing.
1. Turn the Relief Control adjustment screw counterclockwise (out). This lowers the initial relief set-point, allowing the set-point to be
increased to the desired setting.
2. Loosen a tube fitting at a high point on the valve. This allows the cover to vent trapped air during initial filling of the valve.
3. Start the pump to supply fluid/pressure to the valve.
4. Tighten the tubing when all air is vented from the cover as indicated by continual flow of fluid.
NOTICE: THE RELIEF SET-POINT SHOULD BE LOWER THAN DESIRED AT THIS TIME.
5. Turn the Relief Control adjustment screw clockwise (in) slowly, allowing time for the pressure to gradually increase to the desired
set-point.
