Structure

- Full Port or Reduce Port

- One Piece Body,Top Entry,Floating or Trunnion Mounted

- Bolted Bonnet with spiral-would gasket

- Fire Safe Design

- Anti-static Design & Blow-out proof stem

- Double seat structure

- Nace MR-01-75, Optional Locking Device

- The action principle is when the handle drives the stem & ball with 90°rotation to open & close valves. When handle is parallel with body channel, valve is opening. On the contrary, when the handle is perpendicular to body channel, valve is closed. The locating plate can do the limit control.

- The seat is double sealing and soft sealing. These're very convenient to replace, and the technology is also very simple.

- Direct mounting pad also called Top mountain Flange, is suitable to this ISO 5211 Standard.

Features
1:The top enty ball valve features with integral body, top trunnion mounted ball. This type of valves gives convenient of in-line repair or repalcing valve internal components without removing the body from the pipeline. The seat seal design uses unique two-level soft sealing and metal to metal sealing to from triple sealing. The seat piston is designed after accurate calculation to ensure sealing reliablility with small open/cloae torque and easy operation. The valve is widely used in the nature gas and oil pipeline, thr industries of petrochemical, medicine, city construction, etc.
2:Its most difference from common ball valve is that its maintenance can be made on pipe line and without dismounting from the pipe line. The back space seat structure is adopted for the seat and the rear portion of seat retainer is oblique angle to prevent accumulation of impurity from affecting back space of seat.
3:It's featured by its small torque and reliable seal; and unlike common ball valve types, its seat with a spheroidal structure can adjust the seal position automatically.
4:Trunnion-mounted ball: Features a fixed ball and floating seat rings. Bearings absorb the side load generated by the pressure acting on the ball.
5:Independent ball and stem: The ball and stem are independent to minimize the effect of side thrust from pressure acting on the ball.
6:Double block and bleed (DBB): Both seats hold their respective pressures independent of the body cavity pressure which is ideal
to verify the sealing of the seats.
7:Self-relieving seat rings- two seat rings assure bi-directional sealing of the valves.
8:Soft-seated valves: In valves designed for standard service, a resilient material is inserted into the metal seat holder to provide a soft-seating acting in addition to the metal-to-metal seating between the ball and seat rings.

Optional Features
1:Emergency sealant injection stem seal and seat face
2:Metal seated valves
3:Double piston effect seats
4:Extended stem and fittings for below ground service
5:Numerous body, trim, seal area overlay and seal materials available
