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℃.
Sleeve type soft seal plug valve is mainly composed of valve body, cock, seal ring seat and valve cover. The valve body adopts the straight cylinder type internal cavity structure, and the surface of the internal cavity adopts different surface hardening technology to improve the hardness of the valve body sealing surface, wear resistance and corrosion resistance, so as to adapt to different working conditions.
Electric butterfly valves control the flow of process media by moving a round disc to an open or closed position. When the disc is open it is held parallel to the pipes, and media is permitted to flow past it on either side and into the next section of pipe.
Wafer high performance butterfly valve provides a cost-effective solution for a wide range of applications where bubble-tight shut-off is required. Utilizing an eccentric disc and offset shaft, the design incorporates the flexible-lip sealing system into a lightweight, compact body. The result is that in many cases the valve can replace globe valve and gate valve yet easier operating, longer lasting and lower cost.
Axial flow check valve products: by the valve body, the diversion body, the axial movement of the disc and spring components. The product can effectively prevent the reverse flow of pipeline media and ensure the safe operation of pipeline equipment and system.
Design features of axial flow check valves：(1) design with shock absorber spring, to avoid the common check valve open when the direct impact between the disc and the valve body produces vibration and noise.
