Ball valves for the Oil & Gas sector

GN HC

Valvola a sfera alta ciclicità

High cyclicality

GNHC series valves are designed for high pressure CNG applications where reliability, high cycle resistance, and continuous operation are required. They are particularly suitable for compressed natural gas distribution systems, compressors, SKID units, and industrial high-duty applications.

The high cycle ball valve configuration ensures reliable performance even under frequent opening and closing operations. The compact and reinforced body design provides mechanical strength and operational stability in high-pressure environments.

Manufactured in carbon steel, GNHC valves are designed for demanding applications. The BSP, NPT and SAE threaded connections allow flexible integration into hydraulic and high-pressure gas systems.
