  • Selection of chemical valves

    Most of the media in chemical production equipment are highly toxic, flammable, explosive and highly corrosive. The working conditions are complex and harsh, and the operating temperature and pressure are high. Once the valve fails, the mild one will cause the medium to leak, and the severe one will cause the device to shut down Stop production, and even cause vicious accidents. Therefore, scientific and reasonable selection of valves can not only reduce the construction cost of the device, but also ensure the safe operation of production.
