Batescrew Button Valve
Deep Installations

Optional column spacers, of any desired length, enable handwheels to be located at a convenient working height.

The long inner control tube, which is in compression when the valve is closed, is supported against bowing by the outer tube.

The valve is self contained, needing only to be supported at the top end.

Two types of clamp are available:
Adjustable spreader bars, as at upper-right, 
or close-support clamps, as seen below.

A very long column should have at least one intermediate clamp.
