Installation method of silent check valve
Silent check valve: The upper part of the valve clack and the lower part of the bonnet are processed with guide sleeves. The disc guide can be freely raised and lowered in the valve guide. When the medium flows downstream, the disc opens by the thrust of the medium. When the medium stops...Read more -
What are the types of valves?
valve is a mechanical device that controls the flow, direction, pressure, temperature, etc. of the flowing fluid medium. The valve is a basic component in the pipeline system. Valve fittings are technically the same as pumps and are often discussed as a separate category. So what are the t...Read more -
