American standard plug valve
I. Introduction:
The X41F American Standard plug valve is suitable for pipelines in various working conditions such as petroleum, chemical, pharmaceutical, fertilizer, and power industries with a nominal pressure of CLASS150-900LBS and a working temperature of -29-180℃, used to cut off or connect the pipeline medium. By installing a balance valve, the total water volume of the system can be controlled within a reasonable range, thus overcoming the unreasonable operating condition of "large flow and small temperature difference". It can also effectively solve the problem of uneven room temperature in heating systems. The plug valve has a simple structure and is easy to maintain and clean. For example, in a tight-fitting conical plug valve, unscrewing the set screw and removing the washer and plug allows the plug to be taken out of the valve body for cleaning and maintenance. This type of valve made of austenitic stainless steel is the choice for the food and pharmaceutical industries. This can simplify the design of the piping system, reduce the number of valves, and eliminate some connecting fittings required in the equipment. Plug valves are widely used in oil field exploitation, transportation, and refining equipment, and are also widely used in petrochemical, chemical, gas, natural gas, liquefied petroleum gas, HVAC industries, and general industrial applications.
II. Features:
①. The movement between the sealing surfaces of the X41F American Standard plug valve has a wiping effect, and when fully open, it can completely prevent the sealing surface from contacting the medium, so it can be used for media with suspended particles.
②. The cylindrical closing member of the plug valve can be opened and closed by rotating 90 degrees, so this valve is very suitable for occasions requiring quick opening and closing.
③. The plug valve has a simple structure and is easy to maintain and clean. For example, in a tight-fitting conical plug valve, unscrewing the set screw and removing the washer and plug allows the plug to be taken out of the valve body for cleaning and maintenance.
