ABOUT US PRODUCTS CONTACT SUPPORT Modulating Float Valves FOR POOL SURGE TANKS Modulating or float valves are used in surge tanks or vacuum D.E. filter tanks when the top of the tank is at an elevation above the maximum pool water level. In this type system, the water level in the surge/filter tank will rise to the same level as the pool water level when the system is shut down. The walls of the tank must be slightly higher than the pool water level. If this is not the case a tight closing level control valve must be used. Modulating float valves are not tight-closing, in fact, our valves are designed to pass some flow when the ball is in the up or "closed" position, so as not to stop main drain flow entirely. The optimum operating condition for the float controlled valve is between 60% and 70% open. DESCRIPTION DOWNLOADS SPECIFICATIONS Float valves are used primarily in surge tanks to self-regulate flow. When high bather loads create displaced water or a surge, commonly found in competition and large body pools, the surge tank handles the overflow. The concept is a balance which influences the water level in the tank (also known as the surge pit). The more the difference, the more the water wants to rush from the pools bottom outlet (main drain). If this flow exceeds the pumps needs, it will flow into and begin to fill the pit. As the water level rises in the pit from this additional surge, the pressure diminishes demanding less flow from the main drain pipe. The equilibrium is established and the water stops rising in the pit and the flow is controlled to the flow rate that the pump is designed for. The float valve raises allowing water to enter the pit in surge conditions and lowers when the water level is modulated.

ABOUT US PRODUCTS CONTACT SUPPORT 200 Series C02 Feed Systems- Controls pH A SAFER WAY DEAL WITH STRONG ACIDS AND THE FORMING OF CHLORINE GAS The simple and natural way of controlling and stabilizing the swimming pool pH is by raising total alkalinity. The PoolLink® 200 series eliminates handling strong acids and the forming of chlorine gas in the filter room or re-circulation system. PoolLink® 200 Series also forms carbonic acid and bicarbonate buffer in water and makes it impossible to lower the pH below 6.8. Multiple models are available for single, double or bulk tank configurations. It is easy to install and operate.
