5467-375 Henry 5/8 Ods x 5/8 Ods Bypass Relief Valve 375Psi

The function of a By-Pass Valve is to handle momentary instances of over pressure (not due to fire) to prevent Pressure Relief Valve discharge.Applications:The Henry Technologies’ 5467 By-Pass Valve is positioned between the pressure vessel and the Three-Way Valve before the Pressure Relief Valve as shown in Figure 2 below. In the event of a high pressure spike, the valve bypasses excess pressure to the low side of the system thus preventing the Pressure Relief Valve from discharging refrigerant into the atmosphere. If the over pressure increases then the Pressure Relief Valve will be activated.The valve is designed to bypass only enough gas to reduce the effects of high pressure spikes. The valve has relatively low flow rates, thus high flow rates would adversely affect system performance. Continuous bypassing of refrigerant for extended periods of time can lead to loss of system capacity, excessively high compressor temperatures, and possible compressor failure. We recommend a sensor be put in the By-Pass Valve discharge line to monitor if the valve is relieving from high to low side. All By-Pass Valves are suitable for use with HFC and HCFC refrigerants and their associated oils, as well as other industrial fluids non-corrosive to brass, steel, copper and Teflon.Main FeaturesBrass constructionExtended ODS connectionsPositive pressure relief during high pressure spikesConsistent operation and reseatingFlow direction arrowTechnical SpecificationsSet pressure range: 150 to 450 PSIStandard set pressures: 250, 290, 330, 350 and 375 PSIAllowable operating temperature: -20°F to +200°F (-29°C to +93°C)
