Sleeve Type Soft Sealing Plug Valve with Pneumatic Actuator

Benefits:

• Double sealing grooves containing sealing rings are incorporated into the design of the inlet and outflow bores’ structure. When the plug is turned, the pressure between the sealing parts adjusts to maintain a tight seal and prevent any leakage. This can happen either when the pressure is increased or decreased.
• The structure of the valve body, which includes two sealing grooves with sealing rings, prevents the PTFE liner from shifting within the valve body and can accommodate any slight deformation the liner may experience as a result of temperature fluctuations. In addition, the structure of the valve body prevents the PTFE liner from shifting within the valve body. The reduced amount of friction that occurs between the liner and the plug contributes to the longer life of the sealing surfaces.
• The top assembly of the plug shaft is comprised of a PTFE membrane, an O-ring, and a gasket. Due to the design of these components, the pressure ratio between the sealing surfaces can be adjusted. This makes it possible for the plug to be rotated easily while still preserving its ability to prevent leakage across the plug’s inlet, middle, and outlet flanges.
• The entire process of closing the pipeline may be efficiently controlled and regulated, regardless of the pressure that is present inside the pipeline.

Sleeve type soft sealing plug valve product structural features

Sleeve type soft sealing plug valve according to ANS is applicable to the cutting and connection of pipeline’s medium that aroused in various industries such as petroleum, chemical industry, pharmacy, chemical fertilizer, power industry, etc. It is under nominal pressure of CLASS150-900LBS and works at the temperature of -29~180℃.

• The product has a reasonable structure, reliable sealing, excellent performance, and a beautiful appearance.
• Its sealing is realized by the sealing face around the sleeve. It has a unique 360-degree metal edge for protection and fixing of the sleeve.
• There is no cavity in the valve for the accumulation of medium.
• Metal edge provides the function of self-cleaning when the plug is rotated. It is applicable to the operation condition that is glutinous sand apt to smudge.
• Its double-direction flow makes installation and uses more convenient.
• The materials of the parts and sizes of flanges can be configured reasonably according to the actual operation condition the customer required, so as to meet the various needs of engineering.
