Ball valves for heavy equipment and firefighting

GB1

valvola a sfera per antincendio

2 way high pressure

GB1 series ball valves provide a compact and high-performance solution for 2-way high pressure applications, designed for sectors such as heavy equipment, excavators, fire-fighting systems, and industrial heavy-duty applications. They are engineered to ensure safety, reliability, and continuous operation even under demanding working conditions.

With carbon steel or stainless steel construction and pressure capability up to PN420 / S6000, GB1 valves are ideal for high-pressure hydraulic systems requiring mechanical strength and long service life. The 2-way high pressure configuration ensures safe and direct flow control.

The series is certified according to international standards including ATEX, CE PED, DNV, EAC, and UKCA, making it suitable for regulated environments and critical applications, including marine and fire-fighting sectors.

GB1 valves are the ideal choice for applications requiring maximum reliability, high sealing performance, and safety in heavy machinery and complex industrial systems.
