Batescrew High Head Valves
Extended Control Column
|Control columns of any length may be ordered. It is desirable for a handwheel to be located approximately 750mm above a platform. When ordering, please specify the distance from invert of the pipe to the desired height of the handwheel.|
Valves with extended columns need to be clamped, near the top of the column, to a headwall or other supporting structure. Very long columns should have at least one intermediate support clamp.
Clamp brackets are supplied with each extended column, together with all necessary spacers, washers, chemical anchor bolts and data sheet, and a suitable masonry drill bit.Avoid bending the column when fitting clamps.
Use additional shims if necessary.
