Seeking advice on how to choose the sealing surface for valves specifically designed for chlorine use
Thread Content
When concave-convex surfaces are used for the valve sealing surface, what kind of surface is generally chosen for the valve itself? ——PS: Can we use the RF surface? Is it specified that the design pressure is around 0.1~0.6 MPa, with a pipe diameter of DN15?
Valves generally use a concave surface. RF cannot be used. In accordance with clause 13.2.13 of GB50316, for Class A2 fluids, \"when soft gaskets are used, flanges with male-female surfaces or tenon-socket surfaces should be selected.\" Class A2 fluids refer to toxic fluids; contact with such fluids can lead to poisoning to varying degrees, and recovery is possible after ceasing contact. These fluids correspond to toxins that fall within the medium or lower levels of hazard in the classification system for occupational exposure to toxic substances, namely high, medium, and low severity hazards”
