Do you know the common classification of electric butterfly valve? Electric butterfly valve belongs to a variety of electric valve and electric regulating valve. The main connection methods of electric butterfly valve are: flange type and wafer type; the main sealing forms of electric butterfly valve are: rubber seal and metal seal. The electric butterfly valve controls the opening and closing of …

The electric ball valve has the action of rotating 90 degrees, and the cock body is a sphere with a circular through hole or channel passing through its axis. The main features of the electric ball valve are its compact structure, reliable sealing, simple structure and convenient maintenance. The ball valve in the pipeline is mainly used as an electric ball valve to cut off, distribute and change …

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…
