Before use the valve should be inspected for signs of damage. If damage is evident then the
valve should not be used.
The valve is operated by the pressure control knob, it is rotated clockwise to increase pressure.
In order to adjust the pressure control knob pull the locking plunger out and hold in that position
while rotating the knob. After the required adjustment has been made ensure the locking plunger
returns to its original position and the knob is unable to rotate. Note: With the locking plunger
pulled out, and if subject to vibration, the pressure control knob can rotate due to the flow forces
inside the unit, always ensure the locking plunger is operating correctly and the knob is locked in
position when not being adjusted. The turning effort on the knob should be reasonably constant
as the pressure is progressively increased. A similar torque should be required to turn the
valve anti-clockwise to reduce the pressure. It is not a linear device, this means that one turn
can increase the pressure by different amounts depending on flow, viscosity and where in the
range the valve is positioned. The handle should be turned at a steady rate and only by hand.
Each test should start with the valve fully open and the pressure increased to the desired value.
At the end of each test it is recommended to inspect the unit for leaks.
