product overview
api standard cast steel floating ball valve is supported by a floating ball by two valve seats. under the pressure of the medium, the ball itself will have a certain displacement, so that it will press to the outlet of the sealing ring of the valve seat to produce a sealing effect. floating ball valve can be divided into integrated ball valve structure and split ball valve structure according to the structure.
product features
1. simple structure, good sealing performance and small torque.
2. both reducing diameter and drift diameter structures are designed with the lowest flow resistance (actually 0).
3. low leakage packing.
4. fireproof, anti-static, anti blow out valve stem design.
5. top mounting flange.
