Why the structure of the pneumatic valve sealing effect so good

Pneumatic valve including pneumatic device and the body, the product of the body with the stem and disc, the valve stem out the upper body and connected to the pneumatic device, the product of the stem and disc for unibody design, whose character is: the extension of the pneumatic device is equipped with plate products, products of the valve body and right in the left body, left the body and the right body by bolt connection, connect the left upper part of the body and the right body bolts through the extension board implementation left body, the right body and extending plate fixed connection. This pneumatic valve is easy to remove and good sealing. The major advantages of the pneumatic valve, simple structure, small volume light weight, low cost, the characteristics of the pneumatic valve is particularly significant, installed in the upper air tunnel, through two five-way solenoid valve control is easy to operate, also can adjust flow medium. Fluid resistance is small, large caliber of pneumatic valve fully open effective circulation area is larger, easy opening and closing fast, disc pull rotation Angle can complete opening and closing, due to the rotation axis force wrench medium close to equal, and the torque in the opposite direction, thus opening and closing torque is small, low pressure can achieve good sealing, the sealing material is nitrile butadiene rubber, fluorine rubber, rubber, four fluorine lining so sealed performance is good, which is suitable for soft hard cascading metal hard seal valve with metal hard seal and elastic sealing advantages, under low temperature circumstances has excellent sealing performance.
