Expanding metal-seal valve is a new type of cut-off valve developed by our company and Sinopec Engineering Incorporation, and its seal assembly has no friction when it opens or closes, so it is easy to operate with a long service life;
More >Parallel single gate structure, pressure self-sealing valve cover, integral body forging, valve seat and gate sealing surface sprayed with hard alloy, valve seat DBB structure design, small fluid resistance, sealing surface is less washed and erosion by medium, There are three types of structures: diversion hole, no diversi..
More >Adopting fixed ball structure, the valve seat and the ball surface are sprayed with hard alloy, which has fireproof, anti-static, valve stem anti-blowing structure design, two-way seal zero leakage, and can also be equipped with purging system, extended stem structure, anti-wear bushing, etc. Other structural design.
More >The hard-sealed plug valve not only has the advantages of small flow resistance and quick opening and closing of the hard-sealed ball valve, but also has the advantages of no opening of the valve opening sealing surface, no labor, and the like, and is suitable for high and low temperature and various corrosive medium pipes,..
More >The opening and closing member of the cast steel gate valve is a gate. The direction of movement of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully open and fully closed, and cannot be adjusted and throttled. The ram has two sealing faces, and the two sealing faces of the ram form a..
More >Forged steel valves are mainly used on the pipelines of various systems of thermal power stations, cutting or connecting the pipeline media. Applicable medium: non-corrosive medium such as water and steam. Compared with other valve products, forged steel valves are characterized by high temperature and high pressure, unique..
More >The hard-sealed disc valve adopts a three-eccentric structure, the valve body sealing surface is welded with hard alloy, the butterfly valve sealing ring is made of stainless steel and flexible graphite, the elasticity is good, the use temperature is high, and the two-way seal has zero leakage.
More >"Power plant valve" is also called power station special valve, which is mainly used for the pipeline of various systems of thermal power station, cutting or connecting the pipeline medium. Compared with other valve products, power station valves are characterized by high temperature and high pressure and unique s..
More >The cryogenic valves are mainly used in ethylene, liquefied natural gas plants, natural gas LPG LNG storage tanks, receiving bases and satellite stations, air separation equipment, petrochemical tail gas separation equipment, liquid oxygen, liquid nitrogen, liquid argon, carbon dioxide cryogenic storage tanks and tank truck..
More >A hydrogen valve refers to a valve that can be used under hydrogen conditions.Hydrogen valves are not a standard for valve manufacturing. Although valve manufacturers will claim or inform users based on user requirements that those valves are suitable for hydrogen conditions. But in fact, the hydrogen valve is the user'..
More >The instrument valve is a pipe accessory. It is a device used to change the passage section and the direction of flow of the medium to control the flow of the conveying medium. The sealing performance of the instrument valve refers to the ability of the instrument valve to prevent leakage of the medium. It is the most impor..
More >Oxygen valves In the physicochemical experiments, gases such as oxygen, nitrogen, hydrogen, and argon are often used. These gases are typically stored in dedicated high pressure gas cylinders. In use, the gas pressure is reduced to the required range by the pressure reducing valve, and then finely adjusted by other control ..
More >That is, the valve body has a two-layer structure in which a medium having a certain temperature (such as steam) can be circulated to maintain the temperature of the medium in the valve. Much like the northern part of China, the sponge is wrapped outside the pipe to prevent the pipe from being cracked.
More >It is a special valve for sulfur recovery and its tail gas treatment. It is a non-standard product. The valve was jointly designed, developed and developed by the company and Qilu Design Institute. In October 1999, the trial production was successful. It has been running successfully in Shengli Refinery, Shanghai Jinshan Pe..
More >Valves with bellows as the stem sealing element are often used in applications where valve stem sealing is critical, such as in high vacuum applications and in the nuclear industry. Use a bellows instead of a stuffing box on a common valve or use it with a stuffing box.
More >It is composed of jacket joint, oil pipe joint and drilling/Christmas tree, and the drilling/ Christmas tree can be on one side or on both sides.Wellhead and drilling/Christmas tree can be attached with under-well safety valves, above-well safety valves, pneumatic or hydraulic control systems for remote automatic control on..
