Stainless steel high platform ball valve is one of the more common
ball valve, mainly used for supporting the use of electric and
pneumatic valves, because above the ball valve also need to add a
driving device, whether it is electric or pneumatic, need to pay
attention to several details:
1) to leave the position of valve handle rotation;
2) the valve shall not be used as throttling;
3) the ball valve with transmission mechanism must be installed
Stainless steel high platform ball valve working principle: is
dependent on the rotary valve to make the valve unblocked or
blocked.Ball valve switch light, small size, can be made into a
large diameter, reliable seal, simple structure, easy maintenance,
sealing surface and the sphere often closed state, not easy to be
medium erosion, in various industries have been widely used;
In addition, the high platform ball valve is mainly used to cut
off, distribute and change the flow direction of medium in the
pipeline.Of course, this kind of valve will also be different
according to the material, the effect is not the same, but the
market above relatively speaking stainless steel is more, some
requirements of cast steel is difficult to achieve.
The stainless steel high platform ball valve adopts the ISO5211
standard platform design, does not need to connect the bracket and
the axle sleeve, makes the actuator installation to be simple.
Stem leak proof design
1. The stem is designed to prevent blow-out.
2, phase seal, conical stem gasket effectively prevent medium
leakage in the process of stem rotation, and in the abnormal boost
state, also effectively prevent leakage.
3, the second phase of the seal, a group of v-shaped composite
packing in compression to the side expansion, thus preventing
4, release the disc spring preload, automatic compensation of
packing and stem gasket wear.
5. Use stem nut to tighten all stem seal systems to prevent
6. Stop back pad secures stem nut to prevent loosening.
Manual locking design
Switch lock prevents the risk of accidental misoperation when the
valve must remain in its current position.The platform and handle
of the ball valve are provided with a keyhole to lock the valve in
the off or open position with a padlock.
Stainless steel high platform ball valve, excellent sealing
performance, large flow coefficient, small flow resistance
coefficient, simple structure, long service life;Pneumatic actuator
has excellent anticorrosive shell, visual position pointer display,
lightweight design, maintenance-free.The mechanical friction of the
actuator is between Ra0.
4 and 0.6, so as to minimize the friction and ensure the life of
the actuator.The smooth components ensure a low friction rate to
avoid metal to metal friction and prolong the working life of the
actuator.Each actuator has been tested by 100% rotation and sealing
in the factory, and its service life reaches more than 1 million
Stainless steel high platform ball valve adopts dewaxing precision
casting, fireproof structure design, unique high platform meter is
easy to install actuator;The valve stem and the valve body are
provided with an anti-static device, the valve stem is provided
with an explosion-proof device, and the steel ball has a pressure
balance hole;Double stem packing and two disc shrapnel devices,
stem leakage in accordance with the German TUV ta-luft test
requirements, the valve body with a clean valve cavity device.
