Batley Valve®
BV 16000 SpoolSeal
he Batley Valve® BV 16000 SpoolSeal butterfly control valve incorporates the use of a replaceable rubber liner for body protection. The valves are normally supplied complete with our own manual, diaphragm, cylinder or electric actuator. The rubber lining is of snap-in type which locks into a body recess and is available in various grades of rubber.
The streamlined shape of the vane provides minimum resistance to flow and the swing through action prevents damage to the liner should the valve overtravel. The body is of solid ring type accurately machined for liner retention, vane and spindle alignment to ensure positive shut-off combined with lower seating torques.
