1.
Without maintenance, adjustment and lubrication, it is easy to install
and operate reliably for a long time at low operating cost. The surface
adopts spray treatment technology, with beautiful luster. There will be
no external leakage. The valve body is of welded construction, so the
valve is light and easy to insulate. It is very simple to install the
adjusting mechanism. The operating handle can be removed and installed
in reverse direction.
2. Since the valve seat is composed of PTFE
sealing ring and butterfly spring, it has strong adaptability to the
changes of pressure and temperature, and there will be no leakage in the
use range.
3. The machining process of the ball has advanced
computer detector tracking detection, so the machining accuracy of the
ball is high.
4. As the valve body material is the same as the pipe
material, it will not cause uneven stress and deformation due to
earthquake and vehicle passing through the ground, so the pipeline is
aging resistant.
5. Integral full welding, equal diameter and
variable diameter channel, fixed ball and floating ball, double piston
effect sealing system, automatic injection sealant type bearing.
6.
In order to prevent static electricity, steel balls and springs are
respectively installed between the valve stem and the ball and between
the valve stem and the packing box, which can keep the electric
conduction between all parts of the valve and the valve body, and let
the current pass through the area to release static electricity. Not
only to prevent fire, but also to prevent corrosion, to achieve
temporary cut-off for timely maintenance.
