Product name:Mechanical encryption soft seal gate valve
Product model:FDZ45X-10/16
Product features
The product appearance and general valve, just inside the stem with the covert clutch device, need to unscrew the wheel bolt is fixed, the special key is inserted into the bolt holes to adjust the on-off state, then the operating handwheel switch valve, the operation is finished, and then screwed on the bolt can be fixed hand-wheel. Because the product look from the exterior with ordinary valves are exactly the same, so mysterious.
The product fully mechanical device, open and close to any location can realize self locking, simple, durable, not easy to be damaged, the anti-theft effect is excellent, without a special key cannot open, mounted on a tap water pipeline, heating pipe or other conduit can effectively avoid the stealing phenomenon, very easy to manage.
