The inline shut-off valve with BSP external thread is a reliable solution designed to ensure precise control and secure interruption of medium flow within air installations. Engineered for versatility, it is also suitable for use with non-flammable and non-toxic gases such as nitrogen, carbon dioxide, helium, or argon, making it an excellent choice for a wide range of industrial and technical applications. The valve operates through a simple manual mechanism – by turning the ergonomic knob, the stainless-steel AISI 304 ball moves into a fully sealed position, guaranteeing tight closure and dependable performance. An arrow on the brass body clearly indicates the flow direction, ensuring easy installation and safe operation. With a robust construction that combines a durable brass housing, stainless-steel ball, and NBR stem sealing, the valve delivers long-lasting resistance to wear and environmental conditions. Designed to withstand working pressures from 25 bar up to 40 bar, depending on the internal diameter DN, and operating temperatures between -10°C and +90°C, it provides consistent performance across demanding environments. This shut-off valve is an essential component for professionals seeking efficiency, safety, and durability in compressed air and gas systems.
