Description of 12 Inch ButterflyValve:

Most of ZECO 12 inch butterfly valves operated by hand-wheel, wrench and handles, pay attention to the operation speed, neither too fast nor too slow, and exert force at proper position. End position is vital important to valve performance. In Close position, ball shall be at right position to seat. The closure parts of the valve seat so close to the campaign and leave the valve seat, the valve sealing performance depends in part on the relative pieces of stem-driven closure of the valve seat to remain sealed and the resulting mechanical force. If the role of a particular incident in the direction of the closure of the closure of the pressure to close the case up from the seat, and that this power is essential. Most of the internal closure of the sliding piece in the valve seat does not rely on force stem seals, but this type of valve position to close the right thing or not is very important. In some cases, when the closure parts close to the final closed position, the driving force needed to close the case may be greatly increased, to reach the required position has been shut down parts of an auxiliary compression. Close cases are not accessible or not stopped in the customs location will have a seal leak and damage. Butterfly Valves requires right position to guarantee sealing. When the indicator shows Close position, movement shall be stopped. Now the 12 butterfly valve priceis affordable.
