Calefactio 3/4" Stainless Steel 4GPM Flow Control Valve

Flow regulators are used to maintain a defined flow rate regard­less of pressure variations of the supply line. Precise flow control improves system performance and in the case of plumbing systems, it provides comfort of use at low pressure as well as water and energy saving at high pressure. When there is no flow or pressure, the o­ring is relaxed. When there is normal pressure, the o­ring subjected to the line pressure is compressed into the seating area. As the pressure increases, the o­ring is compressed further into the seating area. As the pressure decreases, the o­ring relaxes. Since the flow rate for a given orifice changes to the square root of delta P, the o­ring deformation is equal to this thus giving a constant flow over a wide range of pressure variations.

Flow Tolerance refers to the deviation from Nominal Flow tolerated across the pressure range once the threshold pressure is reached. In general the flow tolerance is +/­ 15%.

Working Conditions refers to the usual parameters of the application such as medium (usually drinking water), pressure range (usually 0 to 150 PSI) and temperature range (usually 40 to 150°F).

Threshold Pressure refers to the pressure at which the flow regulator effectively begins controlling the flow. Standard regulators begin controlling at 15 PSI.
