Félholdszelepek

Félholdszelepek, also known as half-moon valves or crescent valves, are a type of mechanical valve primarily used in plumbing and water systems. They are characterized by their distinctive semi-circular or half-moon shaped internal sealing mechanism. This design allows for a quarter-turn operation, meaning the valve can be fully opened or closed with a single 90-degree rotation of the handle.

The half-moon element rotates within the valve body, aligning openings to permit flow or blocking them to stop flow. This mechanism is generally considered simple and robust, contributing to their widespread use in various applications. They are often found in residential plumbing for controlling water flow to fixtures like sinks, toilets, and showerheads, as well as in industrial settings for less demanding fluid control.

Compared to other valve types, félholdszelepek are typically cost-effective and easy to operate, making them a practical choice for many situations. Their quarter-turn action provides a quick and efficient way to manage water flow. However, their design may not be suitable for applications requiring precise flow regulation or for handling very high pressures or abrasive substances. Maintenance usually involves checking for leaks and ensuring smooth operation of the handle.
