Pneumatic globe valves are crucial components in various industries where precise fluid flow control is essential. These valves find extensive applications, particularly in pneumatic control systems.

They come equipped with pneumatic actuators, enabling efficient air or other fluid manipulation. The pneumatic actuator utilises air pressure seamlessly and opens and closes the valve, ensuring swift and dependable operation.

A notable advantage of pneumatic globe valves is their ability to handle high differential pressures. This quality suits them, particularly when a significant pressure drop occurs across the valve. These valves facilitate precise fluid flow regulation thanks to the pneumatic controls, thus sustaining optimal system performance.

These valves shine whether they’re managing airflows within HVAC systems or overseeing the flow of process fluids in industrial environments. Their robust build and capacity to withstand elevated operating pressures make them versatile for various demanding settings.

At Laminar, we specialise in designing, manufacturing, and supplying pneumatic control valves to various industries. Our globe control valves regulate flow rates, pressures, or temperatures for liquids, gases, or vapours. They excel under challenging conditions like industrial water and wastewater treatment plants, chemical and chlorine applications, and chemical and milk of lime systems.

Here are some additional features that set our pneumatic globe valves apart:

  1. High-performance valve actuator: Our pneumatic multi-spring actuators feature reliable construction. They are characterised by short actuating times, improved actuating forces, and effective sealing. We also offer options with electric or electrohydraulic actuators.
  2. Smart Positioner: Our digital positioner is a versatile interface with integrated support for controllers or process control systems. Additionally, we provide mechanical/analog electro-pneumatic IP positioners.
  3. Reliable stem seals: Our technical team can tailor stem seals precisely to match the process fluid, pressure, and required temperature. This design minimises issues related to friction, corrosion, and emissions.
  4. Robust, high-precision valve trims: Our equipment is optimised to handle flow conditions in your plant efficiently by customised design of shape, seats, and material composition.

Pneumatic globe valves are vital for precise fluid control in various industries. Laminar’s offerings come with advanced features tailored to meet the demands of challenging applications.

Solenoid valves are key players in fluid and gas flow control, harnessing electromechanical principles. They feature a coil wrapped around a metal core, known as a solenoid, which springs to life with a magnetic field when an electric current surges through it. This magnetic force sets a plunger or piston within the valve body into motion, opening or sealing the flow pathway.

Noteworthy for their lightning-quick responsiveness and precision in managing fluid and gas flows, solenoid valves find their niche in applications demanding swift and accurate actuation. Think automated manufacturing lines, precise irrigation systems, HVAC setups, medical apparatus, and many industrial scenarios.

On the other hand, pneumatic valves operate in the realm of compressed air, orchestrating the dance of fluids and gases. Unlike solenoid valves, which sing to the tune of electricity, pneumatic valves groove to the rhythm of air pressure, prompting pistons or diaphragms to move when pressurised air steps onto the stage.

Pneumatic valves steal the spotlight when electrical power may be elusive or where explosive atmospheres lurk. Industries such as oil and gas refineries, chemical plants, mining ventures, and automobile manufacturing hubs rely on pneumatic valve systems for their steadfast reliability and safety features.

Pneumatic control valves are operated using compressed air or gas as their power source. They utilise pneumatic actuators to regulate fluid or gas flow through a system. These valves are known for their quick response time, reliability, and suitability for hazardous environments. Pneumatic control valves are often preferred in oil and gas, chemical processing, and manufacturing industries.

On the other hand, electric control valves use an electric motor or solenoid to operate the valve mechanism. They rely on electrical signals to open or close the valve, allowing precise control over flow rates and positions. Electric control valves offer benefits such as accurate positioning, remote operation capabilities, and integration with automation systems. They are commonly used in water treatment, HVAC systems, and food processing industries.

The choice between pneumatic and electric control valves depends on several factors, including application requirements, environmental conditions, cost considerations, and system compatibility. While pneumatic control valves excel in specific scenarios where quick response time is critical or hazardous environments need to be considered, electric control valves provide precise positioning capabilities. They can be easily integrated into automated systems.
