Note that volatile liquids, such as hydrogen peroxide (H2O2) and sodium hypochlorite (NaCIO), vaporize in those dead spaces, which may cause abnormal pressure increase in the valve. (When the internal pressure abnormally increases due to vaporization, the gas will be compressive fluid. If the valve breaks in this state, it will be very dangerous, causing explosion and scattering of fragments.) (2) The maximum working pressure is the value including the water hammer pressure. Be careful that the maximum working pressure is not exceeded during use. * Concerning the allowable pressure for each temperature and material, see the technical documents at the end of this catalog. The types are classified according to the size and material.
