Flange-connection lifting plug valve
PRODUCT STRUCTURAL FEATURES
Flange-connection lifting plug valve acc.to ANSl is applicable to the cutting and connection of pipelines medium that are used in various industries such as petroleum, chemical industry, pharmacy,chemical ferilizer,power industry etc under niminal pressure ofCLASS150~1500LBS, and wrrking temperature of-29~550C
MAIN STRUCTURAL FEATURES
1.The product has reasonable structure,reliable sealing,excellent performance and beautiful appearance.
2.Opening and closing of the valve is car rideout while the sealed surface is taken off,so it will not cause abrasion on the sealedsurface
3.lIts characteristic double-direction flow makes installation anduse more Convenient.
