Q77 Clamp V-type ball valve,V-type ball valve

This kind of ball valve is a fixed ball valve, but also a single seat sealed ball valve, the adjustment performance is the best ball valve, the flow characteristic is equal to the percentage, adjustable ratio of 100:1. It has a shear effect between the V-shaped incision and the metal seat, especially suitable for media containing fibers, small solid particles, slurry and so on.

It has the same action of rotating 90 degrees, except that the cock body is spherical and has circular through-holes or channels through its axis. Ball valve in the pipeline is mainly used to cut off, distribute and change the direction of the flow of the medium, it only needs to rotate 90 degrees of operation and a small torque to close tight. Ball valves are best used as switches and cut-off valves, but recent developments have designed ball valves to throttle and control flow, such as V-shaped ball valves.

Using cylindrical spring preload with compensatory movable metal seat structure, reliable sealing performance. The ball core and the seat will not produce blockage or detachment, long service life.

The V-shaped incision on the ball core has a shearing effect between the metal seat, which is especially suitable for controlling high viscosity, containing fiber, solid particles and slurry media. The pulp of the structure manufacturing paper industry is particularly superior.

The flow capacity of the valve is large, the pressure loss is small, and the medium will not be deposited in the valve body cavity, the valve not only has the flow characteristics of approximately equal proportion, the adjustable range is large, the maximum adjustable ratio is 100:1, but also has the function of accurate adjustment and reliable positioning

Product implementation standards:

a. Structure length standard: GB/T12221-2005

b. Connection flange standard: GB/T9113

c. Pressure temperature grade: GB/T12224-2005

d. Test and inspection standard: GB/T13927-2008

Product use:

The utility model relates to an advanced control valve with a right Angle rotating structure, which can be used with a valve positioner to realize proportional adjustment; It can be used with two five-way electromagnetic and control box to realize switch control.

Suitable for gas, liquid, solid particle media control. Because there is no gap rotation between the spool and the seat, it has great shear force and self-cleaning performance, especially suitable for the control of suspension and solid particles containing fiber or small solid particles.

Therefore, this product can be widely used in petroleum, chemical industry, paper making, chemical fiber, electric power, metallurgy, pharmaceutical, environmental protection and other industrial automatic control system.

Packing of Standard Packing: 

Typical bulk packaging includes palletized plastic 5 gallon/25 kg. pails, fiber and steel drums to 1 ton super sacks in full container (FCL) or truck load (T/L) quantities. Research and sample quantities and hygroscopic, oxidizing or other air sensitive materials may be packaged under argon or vacuum. Solutions are packaged in polypropylene, plastic or glass jars up to palletized 470 gallon liquid totes Special package is available on request. E FORUs’  is carefully handled to minimize damage during storage and transportation and to preserve the quality of our products in their original condition

Design features:

① V-shaped valve body is composed of pneumatic actuator and other accessories. It is a kind of advanced control valve with right Angle rotating structure.

Excellent adjustment characteristics: V-type valves have an approximate equal percentage of natural flow characteristics and up to 300:1 adjustable ratio. V-valves therefore provide precise control over a wide range of variations.

(3) Maximum flow volume: due to its streamlined shape and full right Angle rotation control, the maximum volume is particularly high, the passing capacity is particularly large, and the flow resistance is small, so a smaller and more economical and practical valve size can be used.

④ V-type valve adopts double bearing structure, high mechanical stability, small starting torque, to ensure that the valve has excellent sensitivity and induction speed.

⑤ Maximum reliability (safety) : the valve body is an overall structure, durable, the operation is not affected by pipeline pressure, and the valve body leakage can be avoided.

Superior sealing of metal seat: V-type valve uses movable metal seat, with self-compensation function, and has superior sealing performance and long service life. In the flow direction, the leakage is ≤10-6× rated flow coefficient.

⑦ Super shear capacity: V-type valve adopts metal hard seal structure, V-type valve core and metal seat in the rotation process, V-type notch and seat produce a strong shear can cut off fibers and other impurities, and has a self-cleaning function, to avoid the valve stuck phenomenon.

⑧ Compact structure, compact and light, easy installation and easy maintenance.
