Ball valve for mining and drilling

GEF-S

valvola a sfera per industria pesante e estrazione

2 way high pressure

GEF-S series ball valves provide a robust and reliable solution for 2-way high pressure applications, specifically designed for demanding sectors such as mining, drilling, steel plants, heavy industrial systems, and marine environments. Engineered for safety and continuous operation, they ensure high performance even under extreme conditions.

With carbon steel or stainless steel construction and pressure capability up to PN420 / S6000, GEF-S valves are ideal for high-pressure hydraulic systems requiring mechanical strength, reliability, and long service life. The 2-way high pressure configuration ensures safe and direct flow control.

The series is certified for critical environments with ATEX, EAC, and UKCA approvals, making it suitable for explosive atmospheres and regulated applications. The design is optimized for maximum operational safety and resistance to mechanical stress.

GEF-S valves are the ideal choice for applications requiring maximum reliability, high sealing performance, and safety in extreme industrial environments.
