High temperature high pressure butterfly valve In order to meet the industrial requirements of high temperature, low temperature, strong corrosion, strong erosion and long life, Milestone Valve Company generally adopts metal hard sealing butterfly valves, stainless steel, carbon steel and alloy materials, and the high temperature resistance can reach 600 ℃; And the High temperature high pressure butterfly valve adopts double eccentric and three-dimensional eccentric sealing principles. Both of these sealing structures are in the state of media positive flow to achieve the best sealing effect.

1) High temperature high pressure butterfly valve body type: wafer type, lug type, flange type, welding type
2) High temperature high pressure butterfly valve sealing type: PTFE, NBR, elastic metal seal, composite metal seal, metal hard seal
3) The high temperature high pressure butterfly valve adopts more triple eccentric design to avoid the wear of the sealing connection surface, and maintain the integrity of the seal and long service life;
4) High temperature high pressure butterfly valve patented elastic metal sealing ring, which produces uniform compression when the valve disc contacts the sealing ring, achieving elastic compensation and high-performance two-way sealing.
5) High temperature high pressure butterfly valve wide-angle valve seat design avoids excessive squeezing of the valve seat and the valve clapper seal to produce wear and deformation;
6) High temperature high pressure butterfly valve valve disc 360 ° round edge sealing contour design to ensure the maximum flow rate and corresponding percentage control.
7) High temperature high pressure butterfly valve solid valve shaft provides stable support for the disc
8) High temperature high pressure butterfly valve can adjust the flange gland sealing packing to prevent uneven distribution of the sealing packing.
High temperature high pressure butterfly valve adopts standard:
Welding size: GB12224; ANSI B16.25; DIN2559
Structure length: GB/T12221; API609
Pressure test: GB/T13927; API598; JB/Y992
