一.Product Introduction
Top mounted ball valve,The integrated valve body equipped with ball valve can effectively reduce the leakage point and bear high pressure;
The mounted ball valve below DN100 is designed with double inclined plane structure.Under the action of the spring, the valve can self-compensation sealing, ensure the valve in the middle and low pressure have good sealing performance, long service life;Fixed structure is adopted above DN100 to ensure its performance.
Top mounted ball valves are widely used in petroleum and natural gas pipelines, as well as in oil recovery, refining, petrochemical, chemical industry, metallurgy, nuclear power, food and paper equipment.
二.Product Features
1. Integral valve body design, top pivot fixed support, flange structure
2.High-strength integral pivot fixed cue is designed with blowout proof protection structure to ensure accurate positioning of the ball
3、with double blocking discharge function (DBB function), fire and anti-static
4、2-Block O-ring seal, coupled with fire retardant packing structure on the stem, effectively prevents leakage
5、(INCONEL) spiral spring makes the metal seat of nylon seal move towards the ball, with the function of two-way sealing of inlet and outlet
6、Superior standard nylon and PEEK seats ensure an effective seal at low pressure
7、Sealant injector designed to provide an emergency injection of sealant to seal the stem and seat
8、With unique retractable seating technology, ball clubs, stem seals, metal seats and spiral springs can be replaced online
9、Preset drive device platform and screw hole, ready to assemble the drive device required by the customer
