Pneumatic Hard Seal Butterfly Valve
Pneumatic Hard Seal Butterfly Valve Introduction
Pneumatic hard seal butterfly valve utilized a U shape seal ring which is made of stainless steel. The elastic seal ring connects with an eccentric disc which has been polished. The disc separates form sealing face when the valve opened. The disc connects sealing face when valve closed to realize sealing, having the advantages of long service life and good sealing. It is applied to below 550℃.
Pneumatic hard seal butterfly valve is widely used for pipelines to regulate flow or closure fluid in metallurgy, petroleum, gas and other industries.
Pneumatic hard seal butterfly valve Characteristics:
1. The butterfly valve has a simple structure, lightweight and convenient utilization.
2. The valve utilizes U shape stainless steel seal ring, having elasticity. The seal ring, cooperating with the disc, ensure the excellent seal with the disc, under low temperature or high temperature.
3. The three-dimensional eccentricity of the valve is calculated strictly. U shape seal ring has advantages of long service life and excellent seal.
4. Seal facing overlay with STL has the advantages of wear resistance and long service life.
5. The valve has a unique structure and is convenient to use.
6. Heat resistance, low-temperature resistance, and corrosion resistance.
Pneumatic Hard Seal Butterfly Valve Actuator
Pneumatic wafer butterfly valve utilizes GT pneumatic actuator, having double-acting and single-acting (spring reset). It is driven by gear, safe and reliable. Large diameter valve utilizes AW pneumatic actuator. It has reasonable structure, large torque output, double-acting and single-acting.
1. Gear dual piston, large torque output, small volume
2. Cylinder, made of aluminum gold, has lightweight and beautiful form.
3. The manual handle can be installed on the top or at the bottom.
4. Gear connection can regulate opening angle and rated flow.
5. The actuator can be attached to an electric signal indication or other attachment to realize automation.
6. ISO05211 ensures installment of product
