Product Introduction: Product model: DHT43X/H/F/R Application of handle driven flange eccentric butterfly valve The handle driven flange eccentric butterfly valve adopts a precise U-shaped elastic sealing ring and a three-level metal hard sealing structure with three eccentricities. It is widely used in pure pipelines such as metallurgy, power, pet1
Sealing characteristics of valve seats: The valve seats of floating ball valves are mostly made of polymer materials such as polytetrafluoroethylene and para polystyrene, which have good sealing performance, but the materials are relatively soft. Due to the softness of the material but the need to achieve a certain sealing pressure ratio, it is nec1
