Q347H high-pressure three piece fixed forged steel ball valve

Product Overview

The Q347H high-pressure three piece fixed forged steel ball valve is used to cut off or connect media in pipelines, distribute and change the flow direction of media. The ball core adopts a fixed spherical design, which does not move under high pressure. During the design, the two sealing rings have sufficient pre tightening force to ensure sealing, which belongs to double-sided forced sealing. Usually, thrust or forward acting bearings are installed on the upper and lower valve stems that are integrated with the ball, which can be used to connect the high and medium pressure pipelines. The seal is made of reinforced polytetrafluoroethylene embedded in a stainless steel ring, and there is no spring at the back of the steel ring to ensure that the valve seat is tightly attached to the ball, maintaining a seal. There are no PTFE bearings on both the upper and lower valve stems, reducing friction and making operation effortless. There are no adjustment plates at the bottom of the small shaft to ensure the joint position between the ball and the sealing ring. Full bore: The flow aperture of the American standard fixed ball valve is consistent with the inner diameter of the pipeline for pipeline cleaning. By selecting different materials, it can be applied to various media such as water, steam, oil products, liquefied gas, natural gas, coal gas, nitric acid, acetic acid, oxidizing media, urea, etc.

Performance Characteristics

• Effortless operation: The ball is supported by upper and lower bearings, reducing friction and eliminating excessive torque caused by the huge sealing load formed by the inlet pressure pushing the ball and the sealing seat.
• Reliable sealing performance: The PTFE single sex material sealing ring is embedded in the stainless steel valve seat, and the metal valve seat end is equipped with a spring to ensure sufficient pre tightening force of the sealing ring. When the sealing surface of the valve wears out during use, the valve continues to ensure good sealing performance under the action of the spring.
• Fireproof structure: In order to prevent the PTFE sealing ring from burning out due to sudden heat or fire, causing significant leakage and fueling the fire, a fireproof sealing ring is installed between the sphere and the valve seat. When the sealing ring burns out, the valve seat sealing ring is quickly pushed onto the sphere by the spring force, forming a metal to metal seal and achieving a certain degree of sealing effect. The fire resistance test meets the requirements of API6FA and APl607 standards.
• Automatic pressure relief function: When the pressure of the stagnant medium in the valve chamber abnormally increases beyond the preload 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.
