Gate valves are selected when the media requires a shut-off function, as they allow for minimal pressure loss when fully open. These valves are typically used in applications where frequent opening and closing are not required, and the gate is kept either fully open or fully closed. They are not suitable for throttling or flow regulation. When partially opened, especially with high-speed media, the gate may vibrate, potentially damaging the sealing surfaces and causing erosion. The main difference between gate valve types lies in the design of their sealing elements. Common types include wedge gate valves, parallel gate valves, and double gate valves. Wedge and parallel gate valves are the most widely used. Globe valves, on the other hand, feature a stem that moves perpendicular to the seat. Their short stroke allows for reliable shut-off, making them ideal for both cutting off and regulating flow. Once the disc opens, it no longer contacts the seat, reducing wear and making repairs easier without removing the entire valve from the pipeline. However, the medium changes direction as it passes through, resulting in higher flow resistance compared to other valves. Common types include angle, DC (Y-type), and plunger globe valves. Plunger valves use a plunger instead of a traditional disc, offering better sealing and versatility in flow control. Butterfly valves are characterized by a disc that rotates within the pipe, allowing for quick 90-degree operation. They are compact, lightweight, and easy to maintain, with low pressure drop when fully open. Sealing can be achieved using flexible or metal seals, each with its own advantages in temperature and durability. They are commonly used in large-diameter applications and in industries such as oil, gas, and water treatment. Ball valves, derived from plug valves, use a spherical disc with a bore that aligns with the flow path when fully open. They require only a 90-degree rotation and offer tight shutoff, making them ideal for on/off control. Recent designs also allow for throttling. Ball valves are versatile, suitable for various media, including corrosive substances and gases. Check valves prevent backflow by automatically opening when fluid flows in one direction and closing when flow reverses. Swing check valves use a hinged disc, while lift check valves have a disc that rises and falls on a stem. Both types help maintain unidirectional flow without external actuation. Control valves adjust parameters like pressure and flow by altering the area between the disc and seat. They can be self-driven (e.g., pressure relief valves) or power-driven (e.g., electric, pneumatic, or hydraulic). These valves play a critical role in maintaining process conditions in industrial systems.

Oxygen generator

The air we breathe is about 21% oxygen. Oxygen for industrial use is generated by separating oxygen molecules from the other molecules within a clean, dry compressed air stream. Pressure Swing Adsorption (PSA) is a simple, reliable and cost-effective technology that enables continuous, high-capacity oxygen flow at the desired level of purity. Adsorption happens when atoms, ions or molecules from a substance (compressed air in this case) adhere to a surface of an adsorbent. PSA technology isolates oxygen molecules from other molecules (nitrogen, CO2, water vapor and trace gases) to leave high purity oxygen at the outlet of the generator. The process takes place in two separate pressure vessels (tower A and tower B), each filled with a carbon molecular sieve, that switch between a separation process and a regeneration process.
