ZSSV不锈钢法兰气阀

Pneumatic V-type ball valve is of quarter-turn structure, its use with valve positioner can achieve ratio regulation and its use with 2-position 5-way electromagnetic valve and control box can achieve open/close control. V-type ball is designed to have V-type and U-type notch of special shape,the ball is available with standard Cv value and low Cv value.It has the most advanced cutoff characteristic and control function of ball valve,most suitable for various regulation applications,and has advantage of big rated flow coefficient, big turndown ratio, good sealing dffect, flexible regulating performance, small volume, vertical or horizontal installation,etc.It is suitable for control of such medium as gas,vapor and liquid. It is an ideal product particularly suitable for control of suspension medium containing fibers and fine solid particles.Therefore,this product can be widely used in industrial departments as of petroleum, chemical engineering, papermaking, electric power, foodstuff, metallurgy, etc. Features: 1.V-type ball valve is elaborately designed to have precision quarter-turn structure: it consists of V-shaped valve body and ZSS/ZSH type pneumatic actuator, positioner and other accessories. V-type ball valve does not need repair for a long time and has a long service life,so it is a valve that provides you with truly high efficiency in controlling the process conditions. 2. Integral valve core:V-type valve core and valve stem are of integral structure without mechanical dead space,during rotation of valve core relative to valve seat, apowerful shear force is produced between V notch and valve seat, which can cut off foreign matter such as fibers,etc.,thus avoiding the seizure phenomenon of valve. 3.Big turndown ratio:the turndown ratio of V-type regulating valve can reach 300:1,such wide range ability en sures the control performance of advanced regulating procedures. 4.Maximum discharge volume:its streamlined contour and full quarter-turn control makes the max. value of the volume extremely high and the flow capacity particularly big,this often indicates that smaller and more economical and practical valve size can be used. 5.V-type valve adopts duplex bearing structure:it has a high mechanical stability and small starting torque, thus ensuring the valve has excellent sensitivity and inductivity. 6.Max.reliability(safety):integral vavle body structure,robust and durable,therefore,there is no effect by pipeline presssure, can avoid leakage of valve body. 7.Integral elastic hard sealed seat:V-type ball valve has elastic metallic seat, and super strong reliable cutoff ability.The tightness in flow direction is better than 10-6 × rated flow coefficient. 8.Easy repair:V-type regulating valve is compact and light,easily installed,maintained conveniently and operated simply. 9.Penumatic actuator adopts imported stainless steel cylinder, oil-free lubricated and corrosion resistant,with superstrong durability and reliability.
