DN100 Stainless Steel Butterfly Valve All-Purpose PTFE And Vinyl Butterfly Valve With Durable Clamp
1. Introduction
The butterfly plate of the butterfly valve is installed in the
diameter direction of the pipeline. In the cylindrical channel of
the butterfly valve body, the disc-shaped butterfly plate rotates
around the axis, and the rotation angle is between 0° and 90°, and
when it rotates to 90°, the valve is fully open. This valve is
generally installed horizontally. Butterfly valve is simple in
structure, small in size and light in weight, and consists of only
a few parts. And only need to rotate 90 ° can quickly open and
close, simple operation, at the same time the valve has good fluid
control characteristics. When the butterfly valve is in the fully
open position, the thickness of the butterfly plate is the only
resistance when the medium flows through the valve body, so the
pressure drop generated by the valve is very small, so it has good
flow control characteristics. Butterfly valve has two types of
sealing: elastic seal and metal seal. Elastic seal valve, the seal
can be set in the valve body or attached to the butterfly plate
periphery.
2. Classification

6.4MPa butterfly valve.
(4) high-pressure disk valve. Nominal pressure PN 10.0 - 80.0MPa
butterfly valve.
(5) ultra-high pressure butterfly valve. Nominal pressure PN>
100MPa butterfly valve.
According to the operating temperature
(1) high-temperature butterfly valve. t> 450 ℃ butterfly valve
(2) medium-temperature disk valve. 120 C <t <450 C butterfly
valve
(3) room temperature butterfly valve. A 40 C <t <; 120 C
butterfly valve
(4) Low temperature butterfly valve. A 100 <t < 40 C
butterfly valve
