Q47H Fixed American Standard Ball Valve Purpose:

The fixed forged steel high-pressure ball valve is suitable for long-distance pipelines and general industrial pipelines with Class 150-600Lb and working temperature<150 ℃. Its safety and resistance to harsh environments have been specially considered in its design, and it is suitable for media such as water, oil, steam, etc.

Product Structure Features:

When the stagnant pressure in the valve chamber exceeds the pre tension force of the spring, the valve seat will retract and detach from the ball, achieving the effect of automatic pressure relief. After pressure relief, the valve seat will automatically reset.
When a fire occurs or the valve seat sealing ring is burned or softened due to abnormal temperature rise, under the action of spring and medium pressure, the spherical part of the support ring and the sphere form metal to metal contact, achieving temporary sealing effect and preventing the fire from further expanding, in accordance with the provisions of API 6FA.
3. The sealing of the packing gland adopts a dual sealing ring of PTFR packing and O-ring, which is particularly suitable for gas media. The packing is installed in the packing disc and can be replaced with a new type of SF type self-lubricating sliding bushing with low friction system at any time to reduce the operating torque.
