They work by rising with the water level in the tank which in turn activates a lever which then shuts the valve. When the water level falls, the float ball valve and lever also drops which then reopens the valve leaving water free to return and fill the tank. End Connector Threaded Press-Fit Compression.

One of the methods used to control the flow of water into water cisterns and tanks is the use of ball (aka float) valves. Pegler Yorkshire PB500T ball valve (BSPT) 25mm Brass and handle Red. Crane D181C DZR service ball valve 22mm. Center CB gas lever ball valve 15mm Brass.

Our ball valves are a simple, cost-effective solution for process lines with low pressure drops. PVC Reducing Bush 2-1. Options include floating ball , trunnion-mount and divertable ball valves. High integrity one-piece bar stock ball valves proven to be better than cast type products. The high quality ‘A’ Series low to medium pressure ball valve range is designed.

It is open when the ball ’s hole is in line with the flow and closed when it is pivoted 90-degrees by the valve handle. From standard flanged Worcester controls ball valves to both ANSI and DIN specifications in reduced and full bore, to three piece valves for cryogenic, high pressure, steam, diverter or sampling duty, or high integrity valves , multi-way designs, modulating.
