overview
The American standard flange type card sleeve plug valve is suitable for cutting off or connecting pipeline media in various working conditions such as petroleum, chemical, pharmaceutical, fertilizer, and power industries with nominal pressure of CLASS150-CLASS900 and working temperature of -29-180 ℃. There is an oil groove between the valve body and sealing surface of the plug valve, which can inject sealing grease into the valve seat at any time through the oil nozzle to increase the sealing performance. The material and flange size of the parts can be reasonably selected according to actual working conditions or user requirements to meet various engineering needs.
Structural features:
① The movement between the sealing surfaces of the plug valve has a wiping effect, and when fully opened, it can completely prevent the sealing surface from coming into contact with the medium, so it can be used for media with suspended particles.
② The cylindrical closure of the steel plug valve can be opened and closed by rotating 900 degrees, making it very suitable for quick opening and closing situations.
③ The structure of the plug valve is simple and easy to maintain and clean. For example, the tight fitting circular plug valve can be removed from the valve body by unscrewing the tightening nut and removing the gasket valve plug for cleaning and maintenance. American standard plug valves made of austenitic stainless steel are the best choice for the food and pharmaceutical industries.
