Issues regarding salt-acid resistant desiccant valves
Thread Content
Currently, environmental protection agencies in chemical parks across the country pay close attention to issues related to leaks. Our factory now needs a DN50 suction valve that is capable of drawing in air only, but not expelling it. It must be completely sealed, with no gas escaping at all. I hope the experts here can help me find a suitable product (soft-sealed, capable of only drawing in air and not allowing any air to be expelled). The operating conditions are: working medium as saline acidic gas, normal temperature, and exhaust pressure of 0.3~0.4 Mpa.
