The stopcock opens shuts has the hole circular cylinder, circles is vertical to channel's spool thread revolving, thus achieves opens shuts channel's goal. Stopcock mainly for opening and closure pipeline and equipment medium. The stopcock principal advantage is as follows:Is suitable for operates frequently, opens shuts is rapid, is facile.The fluid resistance is small. The structure is simple, the relative volume is small,

Plug valve, also called cock or stop-cock valves, is one of the most widely used valves for both on/off and throttling services. Their design is fairly simple; the body is comprised of three main parts: body, cover and plug. The plug is a cylindrical, tapered, or generally cone-shaped device that can be raised or lowered within the seat to maintain, restrict or completely shut off flow. The valve is opened by rotation,

Bolt cover,plug 90 degree around.Its sealing is realized by the sealing face around the sleeve.It has unique 360 degree metal edge for protection and fixing of the sleeve.There is no cavity in the valve for accumulation of medium.Metal edge provides the function of self-cleaning when the plug is rotated,applicable to the operation condition thatis glutinous and apt to smudge.Double direction.
