J11w-16t copper globe valve overview:
J11W copper globe valve is also called brass globe valve, brass globe valve is a series of products. Its main material is brass. Brass is also called copper zinc alloy, the most commonly known as 37 brass, that is, the ratio of zinc and pure copper. Because of its good mechanical properties and processing is widely drunk. Brass globe valves are widely used in Marine valves. It has the advantages that ordinary globe valve does not have. Because this kind of valve stem open or close stroke is relatively short, and has a very reliable cutting function, and because the valve seat vent changes and the stroke of the valve disc into a direct proportional relationship, very suitable for the flow of the regulation. Therefore, this type of valve is ideal for use as cutting or regulating as well as throttling.
J11w-16t copper globe valve working principle:
Brass globe valve body and cover are forged brass, seal seat is reinforced tetrafluoroethylene, stem is stainless steel, and handwheel is cast iron. Only for opening and closing all kinds of pipeline or equipment medium operation, not allowed for throttling. Clockwise rotation of the handwheel is closed, otherwise open, the flow direction of the medium is consistent with the arrow of the valve body, without the help of any lever switch.
J11w-16t copper globe valve features:
1, in the opening and closing process, because the friction between the disc and the valve body sealing surface is smaller than the gate valve, so the wear resistance.
2, open height is generally only seat passage diameter L / 4, so much smaller than gate valves.
3. Usually there is only one sealing face on the valve body and disc, so the manufacturing process is better and convenient for maintenance. However, the disadvantages of the globe valve can not be ignored. The main disadvantage is that the flow resistance coefficient is relatively large, so the pressure loss, especially in the hydraulic device, the pressure loss is particularly obvious.
J11w-16t copper globe valve
Suitable for urban construction, chemical industry, metallurgy, petroleum, pharmaceutical, food, beverage, environmental protection and other fields.
