Telescoping Valves

WATERMAN TELESCOPING VALVES (TS-2 Series) are used in tanks, lagoons, and treatment plants for drawing surface water from one holding area to another or for regulating fluid levels between tanks.   Their unique design uses a siphon to move the water.  Unlike opening a gate, they will not disturb sediments on the bottom of the tank.   They are also commonly called decanting valves or sludge draw-off valves.
