Types of Valves

In pneumatic systems, valves are the core pneumatic control components that function similarly to the "nervous system" of the human body. By controlling the flow direction, pressure, flow rate, and on-off of compressed air, they directly affect the accuracy, response speed, and reliability of the pneumatic system's actions. Fokca offers a comprehensive range of high-performance valves designed to meet diverse industrial and pneumatic system needs. Our valves are engineered for precise control, durability, and efficient operation across various applications.

Valve Introduce

Valve is a control component in pneumatic systems, mainly used to control the flow direction, pressure, and flow rate of compressed air, thereby achieving the start stop, speed, and direction control of actuators such as cylinders. Among various pneumatic components, it belongs to the control pneumatic component and is often used in combination with actuator components and gas supply components.

Due to different industries and application environments, there are different types of valves with their own characteristics, which play unique advantages in different application fields, such as angle seat valves for high flow control, check valves for medium flow control, and solenoid valves for small-scale flow control. The following is an introduction to their specific properties and characteristics:

Common Types of Focka Vlves

Angle Seat Valve

The most obvious feature of Angle Seat Valves is its unique structural design, which adopts a right angle design. The valve seat is at a 45 ° or 90 ° angle to the pipeline, used for large-scale flow control.The angle seat valve is a type of valve with High flow rate, low flow resistance,which used to control the flow of gases, liquids, and steam. Due to its compact structure, precise operation, and quick response, along with its unique water hammer prevention function, it is widely used in high-temperature, high-pressure, and other demanding environments.

Globe Valve

Globe valves provide accurate flow control and reliable shut-off capabilities. They are designed to handle a wide range of pressures and temperatures,

ensuring consistent performance in demanding environments.

Solenoid Valves

The solenoid valve utilizes the principle of electromagnetic induction to provide fast and precise switching control.

Its unique control method enables low power consumption and long service life.

They are available in various configurations to accommodate different pressure and flow requirements.

Other Valves

Fokca also supplies a variety of other specialized valves tailored to specific applications, including check valves, ball valves,

Angle seat valves, and globe control valves... These products are designed to provide consistent performance and long-term reliability.

Fokca's valve solutions are manufactured to high-quality standards, ensuring precision, durability, and reliable performance.

The Different Characteristics Of Valves

The following is a detailed introduction and comparison of the properties of three types of valves: angle seat valve, check valve, and solenoid valve. You can refer to them as follows:

Characteristic	Angle Seat Valves	Globe Valves	Solenoid Valves
Structural Design	Right-angle design with valve seat at 45° or 90° to the pipe, piston-driven	Linear motion valve with plug perpendicular to flow path, handwheel or actuator-driven	Electromagnetic coil-driven plug, direct-acting or pilot-operated structure
Control Method	Pneumatic/electric actuator	Manual/electric/pneumatic	Electromagnetic coil energization control
Flow Characteristics	High flow rate, low flow resistance	Medium flow rate, adjustable	Low to medium flow rate, rapid switching
Response Speed	Fast	Slow to moderate	Extremely fast
Sealing Performance	Excellent	Excellent	Moderate to high
Pressure Resistance	High	High	Moderate to low
Suitable Media	Liquids, gases, steam	Liquids, gases	Clean gases, liquids
Main Applications	Industrial process control	Pipeline regulation/shut-off	Automation systems
Maintenance Complexity	Moderate	High	Low
Cost	Moderate to high	Moderate	Low to moderate

On the basis of fully understanding their attribute differences, when facing specific application requirements, one can choose the appropriate valve types, which can not only achieve the desired effect but also minimize maintenance and replacement costs, and maximize efficiency.For example, when facing application industries such as chemical, energy, and water treatment that require high pressure and high-precision flow control, a globe valve with reliable sealing and flexible adjustment is needed. This requires the part of valve core to control fluid on/off or adjust flow rate through linear motion, which can demonstrate good sealing and flow regulation capabilities.

Valve Types by Application

FAQ

Q1.What is the difference between ball valve and gate valve?

Ball valves use a rotating ball with a bore to control flow—ideal for quick shut-off and tight sealing.Gate valves use a lifting gate mechanism—better suited for full open/close operations but slower to operate.

Q2.How to choose the right valve for water system?

Consider pressure rating, flow control needs, pipe size, and whether the system requires manual or automatic operation. For residential or irrigation systems, ball valves and check valves are common. For treatment plants, consider control valves with corrosion resistance.

Q3.Which valve types are best for corrosive environments?

Use stainless steel valves, plastic body valves, or diaphragm valves. These materials and designs resist chemical corrosion, making them suitable for acidic, saline, or wastewater applications.
