IMPORTANT
The valve is delivered with relief pins. These pins MUST BE removed from
the valve body before working with the valve.
Once actuation tubing has been set up, and pressure
has been adjusted to 450 kPa (65 psig), actuate the
valve and remove the pins. You may need to increase
the pressure a little to ease hand removal of the pins.
Remember, make sure to properly readjust the
actuating operating pressure after removing the pins,
if you had to change it. Keeps these pins in a safe
place. You may want to re-use them for valve
maintenance. It is good practice to re-install the relief
pins if the valve is not used for a long time.
For details refer to the instructions provided by the valve manufacturer.
