The following is a recommendation for ordering a valve: 1. Nominal diameter of the pipe connected to the valve. 2. Valve usage conditions, installation environment, fluid medium, medium temperature range, pressure range. Pressure - Temperature Ratings To meet your exact needs, pay special attention to the pressure - temperature rating of your valve. Pay special attention to the sealing material and gasket material, which to a large extent determine the pressure-temperature rating of the valve. According to the actual needs of the designated sealing material and precipitation materials to meet or better than the actual needs. 3. The type of valve gate valve, globe valve, check valve, ball valve, butterfly valve, regulating valve, etc. 4.
