◆Product Overview
High-performance two-way pressure butterfly valve is my company technical personnel in the absorption of similar foreign products structure and characteristics
it overcomes the defect of existing in the original product is in use after the optimization design,make its more durable service life,more reliable seal
Eccentric butterfly valve uses the three dimensional design principle of sealing pair is composed of two overlapping cones inclined section.butterfly plate
rotation center after the eccentric value of valve body,valve seat,realize the opening and closing of instantaneous contact and separation,and the disc
sealing, ring metal and graphite layer structure to realize labyrinth seal,can make the small torque of valve butterfly valve sealing performance,and can
guarantee two-way pressure butterfly valve adopts reduce eccentric value and enhance the butterfly plate,the strength of the valve spindle,actuators
etc to support zero import and export bidirectional sealing leakage,
The product quality is stable and reliable,by domestic and foreign companies a lot,well received by users,is worth you highly reliable quality products.
◆Use
High-performance two-way pressure butterfly valve is widely used in high,medium and low pressure pipe,high temperature,low temperature,and used as
stop and regulating.Widely used in thermal,electric power,petroleum,chemicalindustry,metallurgy,energy,water conservancy,environmentalprotection,
food,medicine,city building water and drainage industry,especially suitable for sealing requiring higher level.
◆ Characteristics
1,The oblique ellipse butterfly plate radial dynamic balancing sealing system,force approximate balance valve on both sides of the import and export,
and the valve of small open torque,direction,sealed performance is reliable,can achieve two-way pressure 100%;
2.The valve sealing surface adopt and metal sealing ring,through high precision machining,sealing section for elliptic,it and valve seat sealing surface
metal seal.when the valve opening and closing,butterfly plate seal face at various points along the 360° circumferential moments or out of contact,fast
and exact implementation can open or close the action;
3.Use the three eccentric structure,namely on the basis of the double eccentric butterfly valve added a eccentric Angle.
