AshTech - Model 6000 -Indexing Valves
Sequencing or indexing valves are essential when pumping to a large pipe network or to pockets of areas on landscaped commercial areas, as they can dose up to 6 outlets in sequence using a single pump. They are used for wastewater pressure systems which require dosing of multiple sections or zones. Indexing valves reduce the pump capacity bringing significant savings in pump and energy costs.
The 6000 Series line of distributing valves offers exceptional reliability and durability even under the dirtiest water conditions.
With a metal die-cast body, the 6000 series valves are capable of high pressure applications and are recommended to be used on pump fed systems. The 6000 series is ideal for onsite wastewater and effluent water applications.
3The 6000 valve is available in 4 or 6 outlet models that are cammed for 2 to 6 zone operation. With only one moving part (the stem and disk assembly), the valve is easily serviced and maintained. The valve requires 57 litres/min (15 GPM) to operate and works at pressures from 25 to 150 PSI (1.7 bar to 10 bar).
For direct pump - fed installations, the 6000 Series Distributing Valve is directly connected to the discharge side of the pump and is cycled from one zone to the next by turning the pump off and on. In wastewater systems this is usually done automatically by the pump float switch cutting in and out as the water level rises and falls. Install the valve as close to the pump as possible and ensure suction line to the pump has a proper check valve installed and all joints are completely sealed.
