650psiMaximum Δp(45 bar)Gestra ® <strong>Float</strong> <strong>Trap</strong> •<strong>Liquid</strong> <strong>Drainer</strong>Class Rating: PN 63 Available Sizes: 1", 1½" and 2"(DN 25, 40 and 50)<strong>UNA</strong> <strong>27H</strong> Capacity ChartsThe charts show the maximum capacities for hot water.The capacities are a function of differential pressure or thedifference between inlet and outlet pressures for the trap.For example, at a 200 psi differential, the 1" <strong>UNA</strong> 27hS withan orifice 28 has a hot water capacity of about 1,700 lb/hr.For cold water and other fluids, please consult your localFlowserve Gestra representative.Orifice NumberThe orifice number listed on the capacity line refers tothe maximum differential pressure (in bar) for which the<strong>UNA</strong>27hS with that orifice may be used. Each orifice hasa different diameter and will provide a different capacity.Select the line which is appropriate for the applicationwithout exceeding the maximum differential pressure.Maximum ServicePressureRelated TemperatureMaximum DifferentialPressurePressure / Temperature Ratings[ psig] 915810680650[ barg] 63564745[ °F] 482572752842[ °C] 250300400450650psig (45 barg)NOTE: At a 200 psi differential, the <strong>UNA</strong> 26hS must beused only with orifice 22 or orifice 32.
