A Y McDonald Natural Gas Ball Valves – 860 Series
TAMPERPROOF, 175 PSIG, FLAT HEAD, BRASS BALL, LOCKWING
Precision machined and offers bubble tight leak protection both open and closed. Ball Valves offer the added feature of lower and more
closely controlled operating torques for the life of the valve. The brass ball rides between two PTFE port seals that require no lubrication. The stem has a double o-ring seal and cannot be removed from the valve. The body and endpiece threads are pinned to prevent disassembly without damaging the valve. No field adjustment or maintenance of this valve is needed. These valves are designed for use with natural, manufactured and L.P. gas only.
