Lever-operated gate valves are a type of industrial valve designed to control fluid flow within pipelines and systems. These valves are manually operated using a lever or handle, enabling users to open or close the valve by lifting or lowering a gate inside. Lever gate valves are typically unidirectional, allowing flow in one direction, making them suitable for applications where specific directional control is required. They are constructed from materials like cast iron, bronze, and brass, chosen based on compatibility with the fluid being controlled. The pressure and temperature ratings of these valves vary depending on their design and material, ensuring safe operation within specific ranges. Lever gate valves find common use in industries like water supply, industrial processes, and more, where manual control of fluid flow is essential. Their advantages include simple and reliable operation, forming a tight seal when closed to prevent leaks. When selecting a lever gate valve, factors like material compatibility, pressure, temperature, and directional flow control requirements must be considered. These valves are integral to regulating fluid flow in diverse industrial and commercial settings.

PN20 Bronze Gate Valves are industrial valves designed for a wide range of applications involving the control of fluids such as steam, water, and gas. These valves are typically constructed with bronze bodies and bonnets, offering durability and corrosion resistance. They are commonly handwheel operated, making them easy to control manually. PN20 refers to the pressure rating, indicating that these valves are suitable for applications with a pressure rating of 20 bar. They can handle a temperature range from -20°C to 180°C, making them versatile for applications with varying temperature conditions. PN20 Bronze Gate Valves are valuable components in industrial systems where reliable fluid control and durability are essential, and they are available in various sizes to suit different pipe diameters.

The AV-1151 is a type of valve designed for applications where a reliable shut-off of fluid flow is needed. The "Flanged PN16" designation indicates that it has flanged ends rated for a pressure of 16 bar. Bronze construction offers corrosion resistance and durability, making it suitable for various industries, including maritime and chemical. This valve operates by raising and lowering a gate to control the flow, providing excellent isolation and tight sealing, making it ideal for critical applications such as water supply, steam systems, and more. The PN16 rating ensures it can handle medium-pressure systems effectively.
