API ANSI JIS Standard Pneumatic V Type Ball Valve
Summary:
VQ640F/H pneumatic ball valve is a kind of high-precision control valve of right-angle rotary structure, which can be divided into pneumatic regulating ball valve and pneumatic v-type cut-off ball valve. It is used in conjunction with valve positioner to achieve proportional adjustment. It cavities with a two-position five-way electromagnetic valve and a control box. Pneumatic v-type ball valve spool is designed with a special shape of v-type notch, with accurate closure and control function, pneumatic v-type ball valve is suitable for various control occasions, with compact structure, small volume, can be installed and other advantages. Pneumatic V type regulating ball valve is suitable for castration of gas, liquid and solid granular media. Because the spool and seat is no clearance between the rotary, so there is a great shear force and self-cleaning performance. It is especially suitable for the control of suspension and solid particles containing fibrous or small solid particles. Therefore, pneumatic v-type ball valve, pneumatic v-type regulating ball valve, pneumatic cut off ball valve can be widely used in petroleum, chemical, paper, chemical fiber, electric power, metallurgy, pharmaceutical, environmental protection and other industrial departments of the automatic control system.
Pneumatic V Type Ball Valve Features
(1) Pneumatic v-type ball valve consists of valve body, pneumatic actuator and other accessories. It is a right Angle rotary structure of the senior control valve. V-type ball valve does not need to be repaired for a long time, long service life, to provide you with a truly efficient control of the process of a valve.
(2) Excellent regulation characteristics. Pneumatic v-type ball valve has an approximate equal percentage of the inherent flow characteristics and up to 300:1 adjustable ratio. Therefore, pneumatic v-type ball valves can provide accurate control over a wide range of variations.
(3) Maximum flow volume. Due to its streamlined shape and full right Angle turn control, this makes the maximum volume particularly high, flow capacity is particularly large, flow resistance is small, so can use a smaller more economical valve size.
(4) Pneumatic ball valve adopts double bearing structure, high mechanical stability, small starting torque, ensure the valve has excellent sensitivity and induction speed.
(5) Maximum reliability (safety). The valve body is an integral mechanism, rugged, operation is not affected by pipe pressure, and can avoid leakage of the valve body.
The Features of Pneumatic Actuators
The new series of pneumatic actuators, double acting and single acting (spring reset), thallium rack transmission, safe and reliable: large diameter valve series AW pneumatic actuator fork type transmission, reasonable structure, large output torque, double acting and single acting.
1. Gear type double piston, large output torque, small volume.
2. The cylinder is made of aluminum alloy with light weight and beautiful appearance.
3. Manual operating mechanism can be installed at the top and bottom.
4. Rack type connection adjustable opening Angle, rated flow.
5. The actuator can choose live signal feedback instruction and various accessories to realize automatic operation.
6. IS05211 standard connection provides convenience for product installation and replacement.
Pneumatic V Type Ball Valve Product Selection
(1) Valve body parameters: nominal size, working pressure, process medium, service situation, valve body material and other series parameters.
(2) Actuator parameters: actuator form, control mode, control signal (4-20ma, 1-5v), action mode (open air type; Air closed type)
