First, the use of American standard cast steel fixed ball valve
The three-piece split forged steel fixed ball valve divides the valve body into three parts along the cross section perpendicular to the valve channel axis at the two valve seat parts. The entire valve is symmetrical along the center axis of the valve stem. It is mainly used in pipelines. Cut off, distribute and change the direction of media flow. API American Standard Cast Steel Fixed Ball Valve Its large pivot structure guarantees accurate ball center position under high pressure, ensuring good operation performance of the valve; standard valve seat adopts spring structure to push the valve seat to the ball, API American Standard Cast Steel Fixed ball valve guarantees good two-way sealing performance at the inlet and outlet; API American standard cast steel fixed ball valve uses its own discharge valve, and the cavity in the valve body can be discharged outward; the pivot shaft adopts anti-blowout protection structure to effectively prevent leakage; The coefficient of the bearing reduces the torque to a minimum, which facilitates valve opening and closing; the effective contact between the valve stem and the valve body makes the antistatic grounding device superior in performance. It has the advantages of excellent performance, high reliability, wide use, and reasonable price.

Structural Features of American Standard Cast Steel Fixed Ball Valve
1. The manual part can adopt the handle of steel plate pressing or the handle of stainless steel casting. The handle is provided with a limit structure. The limit is set at the position where the valve is opened and closed. When the valve is used on a key device, a lock hole is provided on the limit block to lock the switch position to avoid misoperation. There are clearly open and closed logos on the handle.
2. The valve stem is made of A182F (1Cr13) as a whole and forged. The hardness reaches HB220 ~ 250. The valve stem is connected to the handle by a flat key or a spline or a deed, which is highly versatile and easy to disassemble. The valve stem is provided with an anti-blow-out structure.
3. The packing of the valve is braided, a flexible graphite seal ring or a tetrafluoroene seal ring, so that the valve stem can achieve a reliable seal under certain lubrication conditions.
4. According to the needs, the ball valve can be designed as an anti-static structure. A conductive spring is set between the ball and the valve stem, and between the valve stem and the valve body, to avoid static ignition and igniting flammable substances to ensure system safety.
5. Various forms of sealing pairs. According to different working conditions, soft seal, hard seal, fire valve seat and other structures can be selected; below DN150 is a floating ball form, and below DN200 is a fixed ball form.
6. The ball valve seat can be equipped with an auxiliary sealing structure. A grease injection valve is installed at the valve seat and the valve stem, which can be temporarily sealed in an emergency, and the valve stem can be extended according to need to be suitable for laying in the ground.
