スラブゲートバルブ フラットゲートバルブ

A slab gate valve, also known as a flat gate valve, is designed with a single-piece gate that provides a solid barrier to fluid flow when closed. One of its main advantages is the full-bore, through-conduit design, which ensures minimal pressure drop and allows for pigging in pipeline applications. This makes it ideal for oil, gas, and petrochemical industries where maintaining flow efficiency and internal pipeline cleanliness is critical. The floating slab gate creates a tight seal against the seats, offering reliable shutoff even in high-pressure or high-temperature environments. Its simple structure and reduced number of internal moving parts contribute to long-term durability and low maintenance costs. Additionally, flat gate valves are less likely to be affected by debris buildup, ensuring smoother operation over time. These valves are particularly suitable for buried or remote installations where performance and longevity are essential.
