Brass Natural Gas Ball Valves
Locked Natural Gas Ball Valve
The locked natural gas ball valve is a brass gas valve to TS EN 331 standard in MOP 5 pressure class, lockable and sealable when closed. Because it prevents unauthorised opening, it is preferred by gas distribution companies for meter inlet and riser valve applications.
With its full bore design, it offers low flow resistance; thanks to the locking mechanism, the valve is fixed in the closed position and can only be opened by authorised personnel. It is supplied in sizes from 1/2″ to 1″ and in 3/4″ × 1/2″ reducing type.
