The D971X electric clamp type soft seal butterfly valve adopts a double eccentric structure, which has a tighter sealing function as it closes, and reliable sealing performance. The sealing pair is made of stainless steel and nitrile oil resistant rubber, which have a long service life. The rubber sealing ring can be located on the valve body or on1
Low temperature valves refer to valves that can be used under low temperature conditions. Valves with operating temperatures below -40 ℃ are usually referred to as low-temperature valves. Low temperature valves include low-temperature ball valves, low-temperature gate valves, low-temperature globe valves, low-temperature butterfly valves, low-tempe1
The HC41X energy-saving shuttle check valve is mainly used in water supply systems. It is vertically installed in pipelines and can be lifted or lowered by the pressure difference within the system and the weight of the valve disc. It automatically prevents the backflow of medium water and ensures the normal operation and use of pipelines.
The HQ41X ball type ball check valve adopts a rubber wrapped ball as the valve disc. Under the action of the medium, it can roll up, down, left and right on the integral slide inside the valve body to open or close the valve. Silent closure, no water hammer generated, good sealing performance. The valve body adopts a full water flow channel, with h1
The H41H/W lift check valve is selected for use on pipelines under various working conditions, such as petroleum, chemical, and thermal power plants, with a nominal pressure of PN1.6-6.4MPa and a working temperature of -29-550 ℃. Applicable media include: water, oil, steam, etc
D363H/W-C I. P.R butt welded metal hard sealed butterfly valves are suitable for use as opening and closing or regulating media on pipelines with high temperature, high pressure, fire prevention, insulation, and other characteristics. Its main characteristics are as follows: Compact in structure, small in size, light in weight, flexible in operatio1
