Use and characteristic
Pneumatic sanitary butterfly's valve Adopt the electronic polishing of standard, the smooth surface
guarantees to clean, there is not medium that pile up the area ,
will not produce potential pollution . Dismantling and installing
the valve fast, it is swift and easy to make the valve opened and
maintained , make the time of shutting down of course shorten . Apply if food , pharmacy , cosmetics , clean steam , drinks ,
beverage , biochemical industrial process control the occasion
extensively. Have structure compactness , is it dismantle advantage
such as being convenient to load with.
Its main characteristic is:
1, novel in design , rational, the structure is unique , light,
open and close it rapidly.
2, it is small , easy to operate to hold the moment, it is
dexterous to save effort.
3, install in any all right position, maintain it conveniently.
4, the sealed material is ageing-resistant , corrosion-resistant,
characteristic of having long performance life etc..
Adopt the standard
Design standard: GB/T2238-1989
The flange connects size: GB/T9113.1-2000; GB/T9115.1-2000; JB78
The length of structure: GB/T12221-1989
The pressure is tested: GB/T13927-1992; JB/T9092-1999
Executive body
Adopt new-type serial GT type pneumatic carrying out devices ,
there are one pair of function types and single function type
(spring is restored to the throne), gear wheel transmission, safe
and reliable; The heavy-calibre valve adopts serial AW type
pneumatic carrying out devices and pulls out the fork type
transmission, the structure is rational , it is great to export the
torsion, there are one pair of function types and single function
type.
1, gear wheel type dual pistons, it is great , small to output the
moment.
2, the air cylinder selects the aluminium money material for use,
light, the appearance is beautiful .
3, can install the manual operating organization on the top ,
bottom .
4, the rack type joins and opens the angle, specified flow
adjustably.
5, person who carry out available to bring telecom symbol to is it
point out and all kinds of enclosures by realizing the automation
mechanized operation to feedback.
6, IS05211 standard has joined and changed and provided convenience
for the installation of the products.
7, the festival that both ends adjust screw can make the
standardized product on 0° and adjustable range with4°of 90° .
Guarantee the synchronous precision with the valve.
Selecting of the enclosure
According to controlling and requiring to choose the following
enclosures differently:
Cutting off type enclosure : Single automatically controlled electromagnetic valve , pairs of
automatically controlled electromagnetic valve , limit location
switch answer the news device .
Regulating type enclosure : Electric positioner , pneumatic positioner , electric converter.
Deal with the enclosure in source of the gas : Deal with and unite one three times in relief pressure valve of
air filtration , source of the gas.
Manual organization : HVSD hands hold the organization
