Pneumatic actuators are essential components for controlling ball and butterfly valves in industrial applications. The model AT-63 is designed to provide reliable performance, with a standard trademark or customizable options available. This actuator is manufactured in China and falls under HS Code 8412390000.
Key features of the AT-63 pneumatic actuator include:
1. **Position Indicator**: A multi-functional position indicator with a NAMUR standard mounting groove allows for easy installation of accessories like valve positioners and limit switches.
2. **Output Shaft**: The high-precision one-piece gear output shaft is made from nickel-plated alloy steel, meeting ISO5211, DIN337, and NAMUR standards. It can be customized in size and is available in stainless steel options.
3. **Cylinder Body**: Constructed from ASTM6005 extruded aluminum, the cylinder is treated with hard oxidation and offers optional surface treatments such as epoxy coating, PTFE, or nickel plating.
4. **End Cap**: The die-cast aluminum end cap is available in various colors with metal powder coatings, PTFE, or nickel plating for enhanced durability.
5. **Pistons**: The double piston rack is made from cast aluminum or galvanized cast steel, ensuring symmetrical installation, fast operation, and long service life. Reversing the piston allows for direction change.
6. **Stroke Adjustment**: Two independent external adjustment screws allow precise ±5° positioning in both open and close directions.
7. **Spring System**: High-performance combined preload springs are made from premium materials with coating treatment and pre-press assembly. They offer excellent corrosion resistance and long life, making it easy to replace or adjust spring count for different torque requirements.
8. **Bearings and Guides**: Low-friction composite materials are used to prevent direct metal-to-metal contact, simplifying maintenance and replacement.
9. **Sealing**: Standard O-rings made of nitrile rubber are used at room temperature, while fluorine or silicone rubber is used for high or low-temperature environments.
The product comes with multiple images showcasing its design and application. These include detailed views of the actuator in different configurations and environments. Each image provides a clear representation of the product’s versatility and quality. Whether you're looking for a standard or custom solution, the AT-63 pneumatic actuator is an ideal choice for your valve control needs.
Organic Perilla Seed Oil
1. Lower lipids and blood pressure
The rich linolenic acid in Perilla Seed Oil can reduce serum cholesterol, triglycerides, low-density lipoprotein and very low-density lipoprotein, thereby inhibiting thrombosis and preventing myocardial infarction and cerebral infarction. In addition, α-linolenic acid Acid can also reduce blood viscosity, increase blood oxygen-carrying capacity, inhibit the synthesis of triglycerides, and increase the metabolism of various lipids in the body. Therefore, perilla seed oil has a particularly obvious effect in lowering lipids and blood pressure, especially for hyperlipidemia. and borderline hypertension, the effect is more prominent.
2. Protect liver
The α-linolenic acid in perilla seed oil can effectively inhibit fat synthesis, break down fat and excrete it from the body. Daily consumption can prevent the formation of fatty liver.
3. Strengthen the brain and protect eyesight
CCTV's "Encyclopedia Quest" reported that α-linolenic acid is one of the basic raw materials for nerve cell synthesis and a key nutrient that determines the development of human intelligence. It is called "brain gold". Correct supplementation of linolenic acid can improve the IQ and intelligence of infants and young children. Increase by 20%-30%, pregnant women and children must supplement.
