Pneumatic cylinders with solenoid valve

Types of Pneumatic Cylinders with Solenoid Valve

Pneumatic cylinders function as actuators that provide linear motion, while solenoid valves work as on/off switches for controlling airflow and pressure. Combining the two creates the powerful

• Double-acting cylinders with solenoid valves

  Double-acting cylinders are common types of cylinders where air pressure moves the rod and piston in both directions. A double-acting solenoid valve can control the air pressure between the two sides of the piston within the cylinder. This setup allows for greater control over the speed and force of the cylinder's motion, enabling faster operations and frequent use in high-demand applications.

• Single-acting spring return cylinder with solenoid valves

• Rotary actuator with solenoid valves

  Supported by a solenoid valve, a rotary actuator can be activated to control the flow of air in order to make a full rotation from a fixed point. This allows the valve to control the twisting motion of a load going up to 360 degrees continuously. A rotary actuator serves as a compact unit that can directly link to the power source as well as the device that needs to be rotated, helping to save space and design simpler mechanical structures.

Specifications and maintenance of pneumatic cylinders with solenoid valve

Specifications

• Sizes and strokes:

  The diameter of a pneumatic cylinder is usually known as its bore. Common sizes include 1''2'', 2''4'', etc. The stroke is the distance the piston travels inside the cylinder. It determines how far the cylinder can push or pull an object. Typical stroke lengths are 1'' 12'', 2''24'', and custom lengths are available.

• Force:

  Cylinders exert different levels of forces based on their sizes and the air pressure used. Small ones may produce around 10-50 lbs of force, while larger ones can generate several hundred pounds.

• Speed:

  The speed at which a cylinder moves depends on the air pressure and flow rate. Speeds can range from a few inches per second up to several hundred inches per minute for high-speed models.

• Mounting:

  Cylinders have various ways to mount them including flanges, clevises, pivot rods and trunnions. This allows users to secure the cylinder in place at an angle or aligned with the moving part.

• Materials:

  Cylinder bodies are typically made of aluminum alloy, stainless steel, carbon steel, or other materials per customer requirements. The features include the corrosion resistance, strength, and durability.

• Sealing:

  A quality cylinder provides effective sealing. This helps prevent air leakage, dirt ingress, and oil seal parts' integrity, such as NBR (Acrylonitrile Butadiene Rubber) or FKM (Fluoroelastomers).

Maintenance

• Clean:Wipe down the outside of the cylinder with a soft cloth to remove any dust or debris. Avoid solvents that could damage the paint or coatings.
• Inspect:Regularly check for signs of damage or air leaks. Look for cracks, dents, or excessive wear. Examine the piston rod for gouges or scoring. Listening for hissing sounds can detect air leaks at the seals or fittings.
• Lubricate:Apply a small amount of grease to the guide and seal of the pneumatic cylinder's piston rod. This helps it move smoothly and protects it from wear. Use only lubricants recommended for pneumatic components.
• Tighten:Check that all mounting brackets and hardware are secure. Ensure the cylinder is tightly fastened so it doesn't shift during operation.
• Air filter:Make sure the air filter/regulator at the cylinder inlet is functioning properly. It removes moisture and contaminants from the compressed air. Empty the drain bowl regularly.
• Solenoid valve:For cylinders with solenoid valves, check the wires and connectors for security. Inspect the valve body and housing for cracks. Clean any debris from the valve ports.
• Professional check:If there are signs of air leakage into the cylinder or the movement becomes stiff, please contact a professional for repair. Do not attempt to disassemble the cylinder yourself.

Application Scenarios for Pneumatic Cylinders with Solenoid Valve

Pneumatic cylinders with solenoid valves are versatile applications used in various industries. Below are some industries and applications where these valves are commonly used:

• Manufacturing Industry

  Pneumatic cylinders with solenoid valves are commonly found in the manufacturing industry, where they are used to control the flow of air for various tasks like cutting, packaging, welding, assembly, and tightening. In this industry, the valve is usually integrated into the machine to be indirectly controlled by a computer program. They are widely used because they are precise and can increase productivity.

• Robotics

  Heavier-duty solenoid valves are commonly found in robotic arms. These valves are used to control the movement of robotic arms, which are usually used in automated manufacturing processes. For durability and extended service life, robotics usually requires solenoid valves made from zinc die cast, stainless steel, and brass.

• Food Processing Industry

  The food processing industry makes use of solenoid valves for tasks like packaging and bottling of beverages, opening and closing of ingredient hoppers, and controlling conveyor belts. In this industry, provisions for washdown, moisture ingress, and sanitization are very critical, so the solenoid valves are designed to comply with food industry standards.

• Aviation Industry

  The aviation industry uses pneumatic solenoid valves to control the movement of landing gear, doors, and flaps. They are also used in the aircraft braking systems. This valve is popular in the aviation industry because it is often lightweight and can withstand extreme pressure.

• Automotive Industry

  The automotive industry uses solenoid valves in the engine for variable valve timing (VVT) applications. The valve is also utilized in the vehicle's transmission system as well as in the pneumatic braking system.

• Medical Equipment

  Medical equipment makes use of the micro-pneumatic solenoid valve. This kind of valve is found in devices like breathing machines, analytical instruments, and drug delivery systems to control the precise flow of gasses or fluids at low pressure.

• HVAC Systems

  The HVAC (heating, ventilation, and air conditioning) systems also utilize solenoid valves to control the flow of refrigerants in compressors, condensers, expansion units, and applications controller unit piping.

How to choose pneumatic cylinders with solenoid valves

When buying pneumatic solenoid valve cylinders, certain factors are essential in choosing them for particular applications. To select the right pneumatic cylinder system, it's better to determine the purpose of the device within a machine or system. Knowing what job the cylinder will perform will help one narrow choices down to those models that are suited for specific tasks.

The available space where the cylinder will be placed is another important consideration. Large industrial machines may have room for bigger, heavier components, but this is not the case for smaller systems.

The pressure produced by the compressors needs to be compatible with the solenoid valve cylinder to ensure effective functioning. Valves with manual overrides are preferable in situations where safety is a concern. This is because they allow operators to control the flow of air or perform emergency functions.

Buyers need to check that the cylinder material is durable enough to tolerate extreme temperatures and corrosion. Products with dual-direction functionality are preferred because they allow air passage in both directions through the solenoid valve.

Cylinders come in different sizes, so buyers will have to choose between standard and custom sizes depending on what machines they are suitable for. Discussing the application of the device with suppliers can help determine which standard sizes are typically used within certain industries and what custom sizes are also available.

Since safety is always a primary concern in industrial settings, buyers should purchase cylinders that comply with international standards and have laboratories tested to ensure quality and durability. If not sure about the suppliers, ask about their credentials and the laboratory standards required to pass compliance regulations.

Check the warranty and after-sales support provided when purchasing these devices in bulk. Many suppliers offer warranties and excellent customer service when helping with installation or technical details.

It's essential to read reviews from other buyers who have purchased these products in bulk to determine better the reliability and efficiency of the supplier and the product’s quality. Some suppliers will offer a money-back guarantee if the customer is unsatisfied with the product, which should also be considered when buying in bulk.
