Ari Armaturen STOBU Gland Packed Globe Valve (Flanged PN25, Nodular Iron Body)

The STOBU Gland Packed Globe Valve with PN25 flanged ends and a nodular cast iron body is a reliable and cost-effective solution for controlling flow in medium-pressure pipelines. Featuring a linear globe-style flow path, this valve enables precise modulation and effective shut-off for steam, liquids, and gases — making it ideal for heating systems, water networks, and general industrial applications.

The nodular iron body, also known as ductile iron, offers excellent mechanical strength, shock absorption, and resistance to temperature variation. The PN25 pressure rating supports a wide range of process conditions, while the gland packing system ensures a tight seal around the rising stem, preventing leakage and allowing for easy in-service adjustments. With flanged ends for standardised installation, this STOBU valve provides dependable performance and long service life in both on/off and throttling applications.

Manufactured by ARI Armaturen, this valve combines German-engineered precision with rugged dependability, making it a smart choice for everyday process control.
