This sanitary pressure relief valve is a manually adjustable over-pressure device in which the product pushes against the plug of the valve stem. The stem is held in the closed position by the spring, which is adjusted in holding force by an external lockable cap.
Each spring has a force range, dependent upon how much it is compressed. The more compression, the higher the pressure at which the valve will open.
Choose the spring rating large enough to comfortably achieve the desired setting without compressing the spring down to the stack height. Tightening down the adjustable cap to the maximum pressure will limit the stroke of the valve.
For cleaning, unload the valve by turning the cap and backing off the spring pressure.
