First, fill the non-retention design
Product surface structure using double ball ring design the whole package, even with the ball and comprehensive engagement ring, can eliminate the gap between ball and body, space, reducing the accumulation of pollutants and product curing problems, but outside the ring round and full body contact with the body cavity filled structure to ensure that the tank bottom valve body cavity without dead ends, can be completely drained medium, easy-to-valve and pipe cleaning and disinfection, there is no residue retention, do not worry about rot will become liquid mixed with the new fluid retention phenomenon.
Second, the tank bottom flange design
Bottom of the tank ball valve with a special tank bottom surface of flange connections for welding in the bottom of reaction tank or container, the end of the profile and the gravitational radius with an effective emission function, smooth tapered hole and close the tank ball over accumulation in the valve at the entrance to prevent the media, which ensure smooth drainage.
Third, the ball stuck drain hole design
In the sphere of export of the sealing surface to open a small hole in the bottom of the tank valve immediately shut down the state, will remain empty sphere of residue.
Fourth, leak-proof stem design
1. The use of anti-blow out stem design.
2. The first stage sealed, tapered stem with tapered stem seals effectively prevent stem rotation in the process of media leaks, and unusual boost in the state, also effective to prevent leakage.
3. The second stage seal, a combination of V-shaped packing is compressed in the expansion to either side, thus preventing leakage.
4. The release of compressive preload disc springs automatically compensate for packing and stem seal wear.
5. The use of stem nut compress all of the stem seal system, to prevent leakage.
6. Only the back pad fixed stem nut to prevent its release.
Fifth, switch lock design
Switch must be kept locked in the position of the valve to prevent the existing risk of accidental misuse. Platform and the handle with a ball lock, padlock will be used in the closed position or open valve position lock.
Six, three-piece design
Three-piece structure, easy installation, removal and maintenance
Seven high platform design
Directly using ISO5211 actuator platform, without connecting brackets and bushings can be installed drive, easy to implement intelligent
