Product Description Product profile:Category : Pneumatic Butterfly ValveProduct Name: Triple Eccentric Pneumatic Butterfly ValveProduct introduction:Triple eccentric pneumatic butterfly valve adopts a "U" type stainless steel seal ring. This precision elastic seal ring and the 3D eccentric polishing disc contact each other to solve the problem that the seal surface is in the sliding contact friction when the traditional eccentric butterfly valve opened and closed from 0 ° to 10 ° which makes the seal surface separating when the disc opened in a twinkle and seal recovery when the disc closed. It also achieves the purpose of the best seal performance and prolonged service life. Hence this valve is widely suited to the pipeline of medium temperature ≤ 550 oC as the best device to regulate and cut off fluid which is applied in the fields of metallurgy electric power petroleum chemical air gas combustible gas water supply drainage and other corrosive medium.PRODUCT CHARACTERISTICS(1) The sealing ring by the stainless steel plate and graphite composite plate superimposed.It has the double advantages of metal hard seal and elastic seal no matter in the case of low temperature and high temperature it has excellent sealing performance abrasion resistance corrosion resistance and long service life.(2) Unique lengthen valve stem structure effectively increase the distance between the actuator and high temperature media better heat dissipation performance.(3)Single action pneumatic piston actuator prevent midway air source broken spring reset function automatically reset close valve.(4) Valve opening resistance is small butterfly plate sealing surface for an upward raised cone open the butterfly plate circle at the same time to complete the point from the sealing ring solid objects are not easy to pile up on the sealing surface.(5) The use of three eccentric sealing structure valve seat and butterfly valve almost no friction the more closed the more tight sealing function.
