Q747Y-25C hydraulic fixed hard seal flange forged steel ball valve material has a much higher density than cast. The forged steel ball valve is a type of ball valve that rotates around the center line of the valve body to achieve opening and closing. The sealing element is embedded in the stainless steel valve seat, and the metal valve seat tail end is equipped with a spring. When the sealing surface wears out or burns out, the spring pushes the valve seat and the ball to form a metal seal. It has a unique automatic pressure relief function. When the pressure of the medium in the valve chamber exceeds the pre tension force of the spring, the outlet valve seat retreats and disengages from the ball, achieving the effect of automatic pressure relief. After pressure relief, the valve seat automatically resets. It is suitable for general working media such as water, solvents, acids, and natural gas, as well as for media with harsh working conditions such as oxygen, methane, and ethylene. It is widely used in various industries.

Product Introduction

The standard valve seat adopts a spring structure, which pushes the valve seat towards the sphere, providing excellent bidirectional sealing performance for inlet and outlet; By using the built-in discharge valve, the chamber in the valve body can be discharged outward; The pivot adopts an anti blow out protection structure, effectively preventing leakage; Low friction coefficient bearings minimize torque and facilitate valve opening and closing;

The contact between the valve stem and the valve body enhances the performance of the anti-static grounding device.

It has the advantages of excellent performance, high reliability, wide applicability, and reasonable price.

2. Q347F-600LBC American standard professional manufacturer of turbine fixed soft seal flange forged steel ball valve manufacturer:

The valve body is divided into three parts along the section perpendicular to the valve passage axis at the two valve seats. The entire valve is symmetrical left and right along the central axis of the valve stem. The high-pressure forged steel ball valve is mainly used in pipelines to cut off, distribute, and change the direction of medium flow. Its large pivot structure accurately positions the center of the sphere under high pressure, ensuring excellent operational performance of the valve.
