The rotary valve's good to see you know

1. The adjustable limit of the rotary valve is about 150, 1 ( VALTEK adjustable range of ball valve can reach 300:1, the butterfly valve and the CAM flexure valve is adjustable in the range of 100:1) 2. Carefully cut and straight trip valve shaft is stem in and out of the body, each cycle is out of the product, for the straight travel design it is difficult to avoid leakage, it can not to want products into the production process in the system, and produce a larger plant volatile external leakage that is not acceptable. The rotation of the rotary valve design essentially does not exist the problem, because this kind of valve adopts low hysteresis, high thrust actuator cylinder type, can provide more accurate than other forms of actuator higher stability, can provide long-term close to cut off the metal valve seat. 3. Flow capacity, straight trip valve flow capacity is to install valve pipe flow capacity score, improve the method of flow capacity is improved straight trip valve size, usually may is greater than the pipe. Rotary valve capacity is about the same size of 2 ~ 3 times of straight travel valve, rotary valve can be used to improve without changing the amount of the size of the feed line, can greatly reduce the cost, for this reason, part of the rotary valve has been designed to replace the cut-off valve on the surface of the flange in the face of the flange connection, and is equipped with a connection bolt, this type of valve and stop valve are cheaper than they replaced. 4. Resistance to cavitation, throttling in process industry can cause a lot of cavitation erosion, cavitation may damage the pipes, unacceptable noise level, but also can be produced for metering system disturbance caused by the unclear or unreliable readings, rotary valve has a strong design, greatly reduces the caused by water hammer of valve failure, at the same time, the valve core can absorb part of the excess energy, obviously reduce cavitation and related issues. 5. No external leakage, the standard of rotary valve is better than the standard globe valve design of external leakage 100 times, the cut-off valve stem campaign will pull out of the sand dust into the valve which damaged the graphite packing. In the rotary valve stem do not make any move in and out of, and the rotary motion, thus not damage packing, avoid the external leakage. 6. Spare parts, metal revolving valve spare part is much less than cut-off valve, usually also relatively easy to maintain.
