1.Technical Parameter

Characteristics:

• Bi-directional sealing with two seal rings on both side. No packing is needed.
• The gate forms a cavemous port whose role is that when the gate opens,medium may flow away completely without any detention;when the gate closes,it may be completely sealed.
• When the media are of high concentration, it may also keep the valve seat sealed.As there is no detention area,the bottom of the gate without medium accumulation.
• This products is suitable for the loading and unloading of sugar-making and chemical equipment(dryer and reactor)and th outlet of sizing agent in paper making plants.It may also be used for the recycling of old paper mingled with a large amount of imputities.

Advantages:

• 1.Renewable Seat.Easy maintenance and Reliabiliy are economic acquisition for customers.
• 2.Multi-Seat material can be used in different fluids and solid media
