Application
SP-75/180 plastic granules extgruder is suitable for PVC
Various Cables and pipes materials: HDPE/LDPE/LLPE/EVA/ PVC/PP etc.
Features
The first stage extruder is TSE twin screw extruder without die. Through the combination of barrel and screw the extruder can exert its strong ability the thermo sensibility materials like PVC melting, compounding, dispersing and decentralizing under the condition of no back pressure
The second stage is sj single screw extruder. Because of the lower rotating speed, it can melt, compound lengthways and form strands steadily, avoiding over heating;
Various pelletizing line for PVC
Air cooling pelletizing line
Twin stage extruder air cooling pelletizing line is speical for PVC/wpc  compounds for cable, shoe sole, transparent container, and medical applications EVA shield cable compounds; Carbon black materbatches of PE, EVA, etc.
Two Stage Extruder for pvc
This is another application of Tandem Line. Together with special low pressure and short channel die as well as eccentric die-face cutting technology, the tandem line is capable of effectively mixing/compounding PE resins, antioxidants, and peroxides etc. At a low temperature, to minimize premature, crosslinking of polyethlene.
Other materials it can processed
Heat-susceptible plastics: PVC Cables, low smoke and low halogen, transparent and for medical use, package, and sole.

Pneumatic ball valve is a ball valve equipped with a pneumatic actuator. The execution speed of the pneumatic actuator is relatively fast. The fastest switching speed is 0.05 seconds / time, so it is usually also called pneumatic quick cut-off ball valve. Pneumatic ball valve is usually equipped with various accessories, such as solenoid valve, air source treatment triplet, limit switch, positioner, control box, etc., to realize local control and remote centralized control. The valve can be controlled in the control room without running to the site or high altitude and dangerous areas for manual control, which saves human resources, time and safety to a great extent.
The pneumatic ball valve can be closed tightly only by using the pneumatic actuator to rotate 90 degrees with the air source and a small rotating torque. The completely equal inner cavity of the valve body provides a very small resistance and straight flow channel for the medium. It is generally considered that the ball valve is most suitable for direct opening and closing. The main feature of the ball valve is its compact structure and easy operation and maintenance. It is suitable for general working media such as water, solvent, acid and natural gas, as well as media with poor working conditions, such as oxygen, hydrogen peroxide, methane and ethylene. The ball valve body can be integral or combined.
Pneumatic butterfly valve is composed of pneumatic actuator and butterfly valve. Pneumatic butterfly valve is a pneumatic valve that uses the circular butterfly plate rotating with the valve stem as the opening and closing property to realize the opening and closing action. It is mainly used as a block valve. It can also be designed to have the function of regulation or section valve and regulation. Butterfly valve is more and more used in low-pressure large and medium-sized pipelines. Classification of pneumatic butterfly valve: stainless steel pneumatic butterfly valve, hard seal pneumatic butterfly valve, soft seal pneumatic butterfly valve and carbon steel pneumatic butterfly valve. The main advantages of pneumatic butterfly valve are simple structure, small volume, light weight and low cost. The characteristics of pneumatic butterfly valve are particularly remarkable. It is installed in a high-altitude concealed channel, controlled by two position five way solenoid valve, easy to operate and can also adjust the flow medium.
