Electric Butterfly Valve

Description of Electric Butterfly Valve:ZECO electric butterfly valve is named
after electric actuator operated. Butterfly valve in the pipeline for a long
time to use, may be due to special medium, temperature or pressure causes a
small number of problems, encounter these problems, we must think of ways to
solve, and in order to prevent, no problems of the product for regular
maintenance. The leakage of stem sealing usually caused by packing abrasion，
can make up for tightening the packing gland. Too large packing force may
increase stem friction, and make stem to be hard operated and accelerated the
abrasion of packing. 
Good sealing inside valve will be affected the sealing performance because of
the damage or normal abrasion. For the harsh working conditions, the estimation
and repairment beyond the scope of this manual, due to a variety of different
structural forms, if need to know in advance, should cooperate with the
manufacturer to find a suitable method. The external construction of valve is
easy to check and maintain. So rational approach should be taken to prevent
mechanical to damage the valve, prevent valve corrosion by the sediments in the
atmosphere、chemical substances or wet gas and deterioration of its quality.
Thread、bearings or gears work like the working interface should be periodic
lubrication.
Features of Electric Butterfly Valve:1. In the case of no special
request, ZECO electric butterfly valve is usually equipped with German AUMA
electric actuator, in order to use for a long time in the pipeline, ZECO
wouldn't use the price to change the quality, our goal is to allow the user to
select ZECO because ZECO product quality and reliable can use for a long time
for the user in the long-term use of reduce the maintenance costs of pipeline,
rather than a low price;2. ZECO electric butterfly valve adopts hard sealed
valve seat. The hard sealed valve seat surface can be surfacing welded to
prevent the valve from being unable to be sealed due to damage of the valve
seat and sealing surface by strong abrasive media;3. The stem of ZECO electric
butterfly valve is designed in anti blow out, preventing the stem blow out at
the time of maintenance ;4. The material of ZECO electric butterfly valve is
produced in accordance with international standards.
