Description of Air Valve Sealing Ring Located on Butterfly Plate

The air flow regulating valve has two-way sealing performance, which is especially suitable for the condition that the medium has both positive flow and reverse flow requirements; adopting double eccentric sealing structure, it has the function of tighter closure and tighter sealing performance; adopting half-shaft structure for valve stem and honing structure for butterfly plate, it has high strength and flow surface. Large volume and small flow resistance; replacement of valve body material, sealing ring on butterfly plate, replacement of sealing ring material, can be applied to different media; worm gear transmission device is fully closed, can be used in long-term immersion in water, and flexible operation; electric device selection of imported integrated products, can be on-site or remote control, safe and reliable control.
Air flow control valve

The valve adopts double eccentric soft sealing structure, which absorbs the structure and characteristics of similar products abroad, overcomes the defects existing in the use of the original products, and makes its life more durable and sealing more reliable. The air flow regulating valve is suitable for all kinds of pipelines, especially installed at the outlet of circulating water pump to cut off or regulate the medium flow, and can restrain the impact when the pump starts and stops, and is not affected by the medium flow direction. Its structural features are: small volume, light weight, compact structure, quick opening, reliable sealing performance, light labor-saving, long service life and convenient maintenance. The sealing ring is natural rubber, and the valve body adopts carbon steel surfacing stainless steel, which has the advantages of reliable sealing.
