Welcome to purchase discount source super-h plug valve from our company, which is one of the best China super-h plug valve manufacturers and suppliers.


Plug Valve  -- shaped rotary valve by rotating 90 degrees so that the channel port channel port valve plug and valve body communicating or separately, to achieve open or close a valve. Plug valve plug shape into a cylindrical or conical. In the cylindrical valve plug, the channel is generally rectangular; while in the tapered plug, the channel into a trapezoid. These shapes make stopcock (plug  valve )structure becomes lighter, but it also had some losses. Stopcock most suitable as off and on media and shunt applicable, but in accordance with applicable properties and resistance to erosion of the sealing surface, and sometimes can also be used for throttling.


Classification

By Application plug comprising: a soft sealing plug valves, oil lubrication hard seal plug valves, poppet plug, three and four-way stopcock.


Work principle
With a hole drilled through the plug body as the valve opening and closing member. Plug body with stem rotation to achieve open and close action. Small no filler plug valves, also known as "Hancock." Plug the plug body mostly cone (also cylinder), with tapered bore surface of the valve body with the composition of seal pair. Stopcock is the earliest use of a valve, the structure is simple, fast switching, fluid resistance. Ordinary stopcock by the finishing of metal to metal contact between the plug body and the body is sealed, so poor sealing, opening and closing force, easy to wear, usually only for low voltage (not higher than 1 MPa) and small diameter (less than 100 mm) of the occasion.


Advantage

1, plug for the regular operation, open and close rapidly, lightweight.
2, small cock fluid resistance.
3, the plug structure is simple, relative


Application

Plug valve is widely used  for  oil exploration, refining and transportation equipment, but also widely used for  petrochemical, chemical, gas, natural gas, liquefied petroleum gas, HVAC industry and general industry.
