Product details
Spherical airlock valve (dome valve)
1、 Overview
Spherical gas lock valve (dome valve) is a new type of fast closing valve that adopts an internationally advanced gas seal structure. When the valve is opened and closed, there is no contact between the valve core and the inflatable sealing ring. The sealing ring is made of special formula rubber and can be widely used for sealing powdered materials in fields such as power, metallurgy, chemical, food, and pharmaceuticals.
2、 Main features
1. The valve core has no contact with the sealing ring during operation, low operating resistance, and long service life;
2. Adopting inflatable sealing rings with good sealing performance;
3. Pneumatic push rod direct cylinder drive, rotary output, reliable performance, large output torque, capable of working under harsh working conditions.
