Performance:
The valve body is light and small in size.
In order to reduce the heat loss of the valve body, especially in order to ensure the use of the valve at ultra-low temperature, the valve body is specially designed to be light in weight and small in size.
?
1. The long valve stem is used to avoid the external heat and keep the gland at normal temperature to prevent the performance of the cover seal from degrading.
2. Ideal valve seat
In the SW and BW valves, the valve body cannot be removed from the piping. In order not to replace the valve body and seat, a soft contact seat is used. The spool seal is stable with low temperature characteristics Teflon or Teflon containing 15% glass fiber with good performance can also be replaced as needed.
3. The gasification pressure-increasing structure gate valve adopts flexible structure and is fully sealed. The valve body adopts a structure in which a relief hole is formed in the valve core. The filler material is Teflon.
4. Gasket t is made of Teflon material or metal wound gasket containing ceramic filler with stable sealing performance
