The two-position three-way multi-functional pneumatic solenoid valve is available in normally closed and normally open types. The outer shell is made of aluminum alloy, providing high durability and strength as well as excellent heat dissipation. 

It features a high-precision pilot head with a response rate of up to 5 times per second. The sufficient coil winding prevents overheating, and it can be used interchangeably with three plugs. The power connection does not distinguish between positive and negative poles, ensuring safe grounding.

The electromagnetic valves are essential components of on-and-off pneumatic valves. These valves control the opening and closing of pneumatic valves through excitation and demagnetization.

The vertical pneumatic sanitary butterfly valve cylinder is made of whole stainless steel with a polished appearance and high cleanliness for all food and beverage industries. They are adopting the pneumatic driving mode, and driving the valve by compressing clean air so that the circulation and shutdown of the pipeline medium can be strongly controlled.

Tri-clamp, thread, and weld connections are available; welcome to contact us for ODM service!

The fluorine-lined flanged pneumatic butterfly valve is specially used to control corrosive or highly corrosive media. The inner surface of the valve body is covered with various fluorine plastics to choose from, which has the characteristics of high strength and good corrosion resistance.

The pneumatic fluorine-lined valve is used in conjunction with the actuator. It has dual functions of switching and flow adjustment. It can conveniently open and close the gas path without affecting the flow rate, ensuring the repeatability of the flow rate. Slow start-up reduces the impact of instantaneous pipeline pressure on the instrument.

It applies to all kinds of acids, alkalis, oxidants, reductants, organic solvents, and other media.

Assembly by the pneumatic actuator and butterfly valve body, controlled conveniently by a 2/5-way solenoid valve. When equipped with a valve positioner, it can also adjust parameters such as fluid flow, temperature, and pressure. The pneumatic flanged butterfly valve has low fluid resistance, and the butterfly lever can rotate 90 degrees to complete the opening and closing.

The flanged pneumatic hard-sealed butterfly valve features a multi-layered metallic hard seal, offering the advantages of elastic sealing and excellent sealing performance at low temperatures.

Due to the nearly equal forces acting on the butterfly plate on both sides of the shaft, and the opposite direction of the generated torque, the opening and closing torque is relatively small, ensuring good sealing under low pressure.

The pneumatic flange butterfly valve is simple structure, small size, lightweight, and low cost. This feature is particularly significant for pneumatic butterfly valves, installed in high-altitude tunnels and controlled by a two-position five-way solenoid valve for easy operation. They can also adjust the flow medium.

Pneumatic flange butterfly valves, equipped with pneumatic actuators, have relatively fast execution speed and do not require manual labor, greatly saving human resources and time.

The pneumatic triple eccentric butterfly valve adopts a precision J-shaped elastic sealing ring and triple eccentric multi-layer metal hard sealing structure. It is widely used in industrial pipelines such as metallurgy, electric power, petrochemical industry, water supply and drainage, and municipal construction where the medium temperature is ≤425℃. Regulate flow and load-break fluid usage.

The valve adopts a triple-eccentric structure. The valve seat and butterfly plate sealing surfaces are made of stainless steel with different hardnesses. It has good corrosion resistance and long service life. The valve has a two-way sealing function.

The valve is a low-platform rising pole industrial straight stroke pneumatic gate valve (double-layer cylinder with buffer mechanism) and manual with protection mechanism (manual and self-locking air manual switching device). Adopting a double-layer cylinder structure, fundamentally solves the common problem in single-cylinder pneumatic gate valves that the valve body wedge is stuck and cannot be opened. It is also equipped with a buffer mechanism, reducing wear on the sealing surfaces and preventing the gate from seizing.

Pneumatic knife gate valves are mainly used to quickly cut off or start fluid flow. Its blade design allows for a larger channel when open and quickly cuts off fluid flow when closed. Suitable for emergency stop fluid flow situations, such as leak control or emergency shutdown.

The blade design and structure of the pneumatic knife gate valve enable it to effectively cut and process media containing suspended solid particles, such as sludge, waste, sewage, etc.

The AW-type cast iron cylinder consists of two separate cylinders, providing a large output torque, low friction coefficient, and flexible rotation, making it suitable for large-diameter valves. The double flanged butterfly valve with pneumatic actuator features a carbon steel valve body and PTFE-lined fluorine valve plate, belonging to the category of mid-line soft-sealed butterfly valves. These valves exhibit excellent corrosion resistance and chemical stability.

Feel free to contact us for customizing AW double-acting or single-acting pneumatic actuators and valves.

Spring return pneumatic butterfly valve made of ductile iron QT450, with a painted appearance and thickened valve body. Lined with PTFE seal and stainless steel 304 valve plate, the anti-corrosion and wear resistance are improved and suitable for acid and alkaline media. The AW type cast iron cylinder is composed of two split cylinders with large output torque, low friction coefficient and flexible rotation. It is suitable for large-diameter valves.

Pneumatic globe valve is a forced sealing valve. The sealing surfaces of the valve disc and valve seat are made of iron-based alloy surfacing or Stellite cobalt-based hard alloy surfacing, which has the characteristics of good wear resistance, high temperature resistance, corrosion resistance, scratch resistance and long service life. When the pneumatic valve is closed, pressure must be applied to the valve disc to force the sealing surface to prevent leakage.

The valve disc and valve seat sealing surface of the pneumatic control globe valve are made of iron-based alloy surfacing or Stellite cobalt-based hard alloy surfacing. The valve stem has been tempered and surface nitrided, and has good wear resistance, high temperature resistance, and corrosion resistance. Corrosion-resistant, scratch-resistant, and long service life.

The medium flow direction of the stop valve changes from the top of the valve disc to the valve cavity. Under medium pressure, the force to close the valve is small, but the force to open the valve is large, and the diameter of the valve stem can be reduced accordingly.

3-way sanitary tri-clamp L-type and T-type ball valve with pneumatic actuator: The valve body is made of SUS304/316L, which can meet the special requirements of various media in the fields of food, biopharmaceuticals and other fields; it adopts all-inclusive PTFE sealing with no dead corners, and its flow channel is smooth, seamless and easy to clean.

PVC, CPVC plastic pneumatic ball valves are light in weight, have excellent corrosion resistance, are flexible in rotation and easy to use. They are suitable for shutting off the transportation process of corrosive media.

It is suitable for many industries such as drainage and sewage pipeline systems, brine and seawater pipeline systems, acid-base and chemical solution systems, etc.
