Ball valve is a ball with a round through hole as the opening and closing parts, driven by the valve stem the ball around the center of the valve stem for 90 degrees to complete the opening and closing function. According to the structure of the ball valve, there are mainly two kinds of floating ball valve and fixed ball valve; According to the material composition of the ball valve, there are mainly cast steel ball valve and forged steel ball valve. According to the characteristics of the sealing surface of the ball valve, there are mainly two kinds of soft sealing ball valve and metal hard sealing ball valve; According to the valve body structure, there are mainly three kinds of split type ball valve, top type ball valve and all-welded ball valve.
Read moreGate valve is usually suitable for the condition that it does not need to open and close often, and keep the gate plate fully open or fully closed, suitable for water, steam, oil, oxidizing medium, urea and other media pipelines.
Main product types:
Forged steel gate valve, cast steel gate valve, single, double plate gate valve, plate gate valve, etc. Operating forms are: manual, pneumatic, electric, gas-hydraulic linkage and electro-hydraulic linkage.
The globe valve has a very reliable cutting function, mainly used in chemical, electric power and other fluid pipelines for cutting or regulating and throttling use.
Main product types:
Forged steel stop valve, cast steel stop valve, low temperature stop valve, etc. Operation mode: manual, pneumatic, electric.
Check valve refers to the valve that automatically opens and closes the valve disc to prevent the return of the medium by relying on the flow of the medium itself.
Main product types:
Lift type check valve, swing type check valve, axial type check valve, single disc, double disc clamp type check valve, micro slow closing check valve.
Butterfly valve refers to the closing part (butterfly plate) is a disk, revolving around the valve shaft to achieve the opening and closing of a valve, mainly in the pipeline cutting and throttling role. The butterfly plate is driven by the valve stem, and if it is turned 90°, it can complete a opening and closing. Changing the deflection Angle of the plate can control the flow rate of the medium. Commonly used butterfly valves are clamp butterfly valves, lug butterfly valves and flanged butterfly valves.
Low-temperature valve refers to the medium temperature of the valve at -40℃~-196℃, the packing part of the low-temperature globe valve is increased, that is, the valve stem is lengthened, and it can be reliably and stably applied in conditions below the working temperature of -40℃.
Mainly used in ethylene, liquefied natural gas plant, natural gas LPG LNG storage tank, receiving base and satellite station, air separation equipment, petrochemical exhaust gas separation equipment, liquid oxygen, liquid nitrogen, liquid argon, carbon dioxide low temperature storage tank and tank truck, pressure swing adsorption oxygen production equipment.
Main product type:
Low temperature butterfly valve, low temperature gate valve, low temperature ball valve, low temperature globe valve, low temperature check valve, low temperature throttle valve, etc.
Control valve, also known as control valve, in the field of industrial automation process control, by accepting the control signal output of the control unit, with the help of power operation to change the media flow, pressure, temperature, liquid level and other process parameters of the final control element.
It is generally composed of an actuator and a valve. If according to the stroke characteristics, the regulating valve can be divided into straight stroke and Angle stroke; According to the power used by the actuator, it can be divided into three kinds: pneumatic control valve, electric control valve and hydraulic control valve.
According to its function and characteristics, it can be divided into linear characteristics, equal percentage characteristics and parabolic characteristics.
The regulating valve is suitable for air, water, steam, various corrosive media, mud, oil and other media.
Main product types:
Regulating valve commonly used categories: pneumatic regulating valve, electric regulating valve, hydraulic regulating valve, self-operated regulating valve.
Special valves refer to valves that can be applied to various special environments and adapt to various complex working conditions. It is a widely used general mechanical product in the construction and development of the national economy, and plays an extremely important role in the fields of energy, chemical, medicine, agriculture, food, military and other industries. Compared with ordinary types of valves, special valves have obvious characteristics such as extremely complex internal flow, special structure, special materials and special uses.

After the filter cartridge of the filter screen has a certain specification, its impurities are blocked, and when it needs to be cleaned, as long as the detachable filter cartridge is removed and re-loaded after treatment.
Main product types:
Regulator commonly used categories: self-cleaning filter, automatic filter, brush filter, elastic filter.
