Wafer Butterfly Valve -LWBV-4

Pneumatic butterfly valve is composed of pneumatic actuator and butterfly valve. Pneumatic butterfly valve is a

pneumatic valve that uses a circular butterfly plate that rotates with the stem to achieve activation. It is mainly

used as a cut-off valve. It can also be designed to have the function of adjustment or segment valve. The use of

medium-diameter pipes is increasing. Pneumatic butterfly valve classification: stainless steel pneumatic butterfly

valve, hard sealing pneumatic butterfly valve, soft sealing pneumatic butterfly valve, carbon steel pneumatic

butterfly valve. The main advantages of the pneumatic butterfly valve are simple structure, small size, light weight

and low cost. This feature of the pneumatic butterfly valve is particularly remarkable. It is installed in a dark tunnel

at high altitude and is controlled by a two-position five-way solenoid valve. It is easy to operate and can also

adjust the flow medium.

Advantage

The pneumatic wafer butterfly valve has a novel structure. The valve body is constructed to meet the short-distance wafer structure formed by the narrow pipeline space. The external leakage is zero and the internal leakage meets the national standards.

Pneumatic rubber-lined butterfly valve, connection method has flange, wafer, sealing lined with nitrile butad

iene rubber, ethylene propylene rubber, heat-resistant ethylene propylene rubber, natural rubber, neoprene,

fluorine rubber, PTFE, according to medium chemistry Nature has a more reasonable choice.

Pneumatic fluorine-lined butterfly valve, anti-corrosion fluorine-lined butterfly valve adopts a two-piece valve

body combination, the valve seat and the valve body lining are integrated, when the valve is working, only the

all-plastic valve seat and the plastic-lined butterfly plate are in contact with the medium, and the product can

withstand Corrosion of any medium except for molten alkali metal and elemental fluorine, in which D71F46

valve stem and butterfly plate (forging) are integrated, and the surface is evenly coated with a layer of FEP.

The inner surface of the valve body channel is smooth, the fluid resistance is small, the CV value is high, the

flow capacity is strong, and the torque is moderate. It adopts a four-stage sealing structure and is equipped

with a temperature-resistant and anti-aging SI rubber elastic gasket valve seat outside the sealing surface,

which is fully achieved. Zero leakage of the medium.
