Product Overview:

Gate valve is one kind of equipment which can be widely used on oil and steam pipelines in petrochemical plant and coal-fired power plants to connect or truncate the medium in pipelines. Only used for full turn on or full turn off. This valve has the advantage of compact structure，reasonable design,good rigidity,smooth channel and small flow resistance coefficient.double sealing surface were made to wedge type.

Product Feature & Advantage:

1.small flow resistance .the way inside valve is direct through,the media can easily through the inside way, flow resistance are small.
2,operate portably and flexibly,compare with globe valve ,the way of Disc move is Vertical with media whether open or close.

3.it is take a long time to open or close because long stem.

4.Water hammer phenomenon will nor happen because it cost long time to open and close.

5.The medium can flow in any direction on both sides, and is easy to install. Gate valves are symmetrical on both sides of the channel.

Application area:

They are widely used in architectonics,edibles,medicine,chemical,energy,applying and draining
