A stem valve is a mechanical device that controls the flow of gases or liquids.
This type of valve is self-sufficient, operating without an external energy source. It is renowned for its simplicity, ease of maintenance, compactness, and lightweightness, which facilitate effortless installation and transport. Stem valves are employed in various sectors, including pneumatic and hydraulic systems, automotive, industrial machinery, and building facilities, making them versatile across different industries.
The structure of a stem valve includes four primary components: the body, stem, seat, and spring. The valve's operation involves the stem being pressed against the seat by the spring, enabling it to open or close. Stem valves are categorized into two main types: direct-acting and indirect-acting. Direct-acting valves are straightforward and cost-efficient, whereas indirect-acting valves offer enhanced durability.
