Modulating Float Valve

The Float Valves modulates to maintain a constant liquid level in a storage tank by compensating for variations in demand or supply. It can be installed for controlling the flow into or out of the tank by either closing on a rising level or opening on a rising level. This valve is operated hydraulically, a pilot-controlled diaphragm valve. The pilot control comprises an integral variable orifice in the main valve cover along with a remotely mounted float control. The float control gets moved by a slight change on the liquid level. This action varies the pressure in the valve cover and causes the main valve to find a new position. The integral variable orifice can automatically regulate the flow into the cover chamber until the valve can reach a position that is in direct relation to the position of the float control. This action can vary the pressure in the valve cover and cause the main valve to find a new position. The integral variable orifice can regulate the flow into the cover chamber automatically until the valve reaches a position that is in direct contact with the position of the float control.

Non-Modulating Float Valves

Non-Modulating Float Valves are dependent on the 206-PG or 106-PG main valve. It is ideal to allow normal forward flow for filling water reservoirs to a desired high level and in cases where the valve and the pilot of the reservoirs are accessible easily. The valve can work as a two-position valve either in a closed or open position. The valve will remain closed when the reservoir level drops unless the float can reach the pre-determined adjustable minimum reservoir level. The valve then will get opened for refilling the reservoir and tightly closes when a high-water level is achieved. These valves are used mainly in buildings having installations or reservoir tanks in which the pilot and the valve are easily accessible. The on/off service can ensure that the contents of the reservoir are cycled. It will also prevent over cycling of the supply pumps as the minimum quantity per cycle is adjustable.

Dutco Tennant LLC brings to an advanced range of Modulating / Non-Modulating Float Valves in the Middle East. They offer amazing range of performance and can last for a really long time.
