Note: This information is applicable to component numbers of 15, 17, and 18 in table 1.
Operation When the inlet pressure overcomes the set sprirg pressure on the disc, it causes the valve to open, releasing flow to bypass and thereby balance the system pressure.
Factory Test
Registration
Every valve is factory tested for cracking and reseal performance.
