Фланец из нержавеющей стали пневматический шаровой клапан

Our company after 20 years of development, have developed our own products. Many of them are O-type rotary cutoff ball valve is a new generation of patented control ball valve, its use with electronic electric actuator can realize 2-position switching control under the action of working power source. Therefore, it is widely used in the automatic control system of industrial department as of petroleum,chemical engineering, papermaking, metallurge, foodstuff,sewage reeatment, pharmacy etc.to realize cutoff or flow control of the fluid within the transfer piping. Features: 1.Max.reliability(safety):integral vavle body structure,robust and durable,therefore,there is no effect by pipeline presssure,and can avoid permeation of valve body. 2. Integral O-type ball:the ball and valve stem are of integral structure without mechanical dead space,during the rotation of valve ball relative to valve seat,a powerful shear force is produces to control flow or cutoff of the fluid, its service life is more than 10 times that of conventional ball valve. 3.Integral elastic hard sealed seat:O-type ball valve adopts elastic stainless steel hard sealed double-seat structure, has super strong sealing performance,its leakage rate is ≤10-6 × rated flow coefficient. 4.O-type ball valve adopts duplex bearing structure:it has a high mechanical stability and small starting torque,thus ensuring the ball has excellent senstitivity and inductivity.
