Can the check valve replace the ball valve?
- Check valves are not a substitute for ball valves.Ball valve sealing is superior to all kinds of valves, ball valve according to the implementation of different control mechanisms, can achieve a variety of functions, throttling, regulating, temperature control, headstock, vacuum and so on. These are non-return valves that are not available.The main advantage of the check valve is that it can automatically prevent the backflow of medium and prevent back pressure, water hammer and other effects.s
1 and 1/2 ball valve is how much?
- 1 and 1/2 ball valves, DN40mm.The ball (ball valve as the cut-off valve in the marine and marine field), standard GB/T21465-2008 "valve terminology" is defined as: opening and closing parts (ball) driven by the stem, and around the valve axis for rotation of the valve. Can also be used to regulate and control fluid, strong shear force between the metal seat seal V type ball valve V type ball core and welding hard alloy, especially suitable for containing fibers, small solid particles and other media. Switch and multi way valve in the pipeline not only can flow, and flow diversion, flexible control of the medium, but also to turn off any channel to the other two channels. This kind of valve should be installed horizontally in the pipeline. In accordance with the way to drive the ball valve is divided into: pneumatic ball valve, electric ball valve, manual ball valve.s

Butterfly valve, globe valve, ball valve used what is different
- Butterfly valve, globe valve, ball valve used in different occasions:1. valve (Butterfly Butterfly) refers to the closure of parts (valve or butterfly plate) for the disk, around the valve shaft to achieve rotation and closure of a valve, the main cut off on the pipe and throttling. Butterfly valve headstock is a disc shaped disc, in the valve body around its own axis of rotation, so as to achieve the purpose of opening or closing or regulation. Butterfly valve is fully open to fully closed is usually less than 90 degrees, butterfly and butterfly stroke itself has no self-locking capability, in order to position the disc to install the valve stem on the worm gear. Using worm gear reducer, not only can the butterfly plate have self-locking ability, so that the butterfly board stops at any position, but also can improve the operation performance of the valve.Industrial butterfly valve features, capable of high temperature, applicable pressure range is higher, the valve nominal diameter is large, the valve made of carbon steel, the valve plate sealing ring using metal rings instead of rubber rings. Large high temperature butterfly valve welded by steel plate, mainly used for high temperature smoke duct and gas pipe.s
