DN100 Stainless Steel Butterfly Valve All Purpose PTFE And Vinyl With Durable Clamp

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
According to the working pressure
(1) Vacuum butterfly valve. Working pressure is lower than the standard pile of atmospheric calendar butterfly valve.
(2) low-pressure butterfly valve. Nominal pressure PN <1.6MPa butterfly valve.
(3) medium pressure butterfly valve. Nominal pressure PN 2.5 - 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
(5) Ultra-low temperature butterfly valve. t < 100 C butterfly valve
According to the connection
(1)Clamped butterfly valve
(2) flange butterfly valve
(3)Lug type butterfly valve
(4) welded butterfly valve
