The pneumatic knife gate valve simply uses a pneumatic actuator to control the valve, so as to realize the opening and closing of the valve. Pneumatic knife gate valve is a valve driven by compressed air, which can be divided into upper and lower parts, the upper part is a pneumatic actuator, and the lower part is a valve. The opening and closing part of the pneumatic knife gate valve is the gate,…

We all know that the high-efficiency filter is mainly used for the terminal filtration of various filtration systems. It can effectively filter out various suspended particles of 0.5 microns and above, and the purification efficiency is better. Not only that, the high-efficiency filter also has the advantages of low resistance and large filtration capacity. In the actual production environment, hi…

Lengthened butterfly valves are widely used in: chemical, petrochemical, petroleum, papermaking, mining, electric power, liquefied gas, food, pharmaceutical, water supply and drainage, municipal, mechanical equipment, electronic industry, urban construction and other fields.…

Advantages of electro-hydraulic flat gate valve: small flow resistance, and its flow resistance without shrinkage is similar to that of a short tube. The flat gate valve with diversion hole is installed on the pipeline, and the pig can be used for pigging directly. Since the gate plate slides on the two valve seat surfaces, the flat gate valve fluid can be applied to the medium with suspended part…

The regulating valve is also known as the control valve. By accepting the control signal output by the regulating control unit, the regulating valve is operated by power to change the fluid flow. The regulating valve generally consists of an actuator and a valve. According to the power used by the actuator, the control valve can be divided into three types: pneumatic control valve, electric contro…

The high temperature ball valve is a metal sealing structure, the sealing form is metal-to-metal sealing, the metal sealing ring can be exchanged for metal sealing, and the stainless steel plate and graphite composite plate sealing ring is sealed to metal. In addition to electric, the driving forms of hard-sealed butterfly valves include manual, worm gear drive, pneumatic, etc. The disc of the hig…

Nuclear-grade valves are pressure-bearing parts with very strict quality requirements, and it is very important to ensure the quality of their products. The product quality of the valve is guaranteed by the whole process of design, production and use. Doing a good job in valve manufacturing and quality inspection is of great significance to the economical and safe operation of nuclear power valve …

The plug valve is a rotary valve in the shape of a closing member or a plunger. By rotating 90 degrees, the channel port on the valve plug is the same as or separated from the channel port on the valve body, so as to realize the opening or closing of a valve. The shape of the plug of the plug valve can be cylindrical or conical. In cylindrical valve plugs, the passages are generally rectangular; i…
