Product characteristic |
|
¢ÙThe product design manufacture conforms to US national standards ANSI B16.34, BS1873 and so on overseas advanced standard request.
¢ÚThe valve chest contour is the doliform or the streamline shape handsome appearance. The circulation shape to go nonstop to-like. The fluid resistance is small.
¢ÛThe closure (valve petal) uses the conical surface seal with the valve seat packing surface, the closure strength is small, bears the washout, the seal is reliable.
¢ÜThe valve seat may for the replacement type valve seat, be possible to combine and the shutting down packing surface material pair willfully, satisfied operating mode request, extension service life.
¢ÝHeavy-caliber, the high pressure Globe valve uses the lifter according to the shutting down strength's need valve lever's type of drive, and has the rolling bearing type to use the percussion handwheel to reduce the closure strength.
¢ÞThe main body material, the contents material, the padding, fastener's material may combines reasonably according to the user request or the actual operating mode condition. |
