Safety relief valve should only be used selectively where the materials chosen are compatible with the fluid used and will not cause corrosive buildup, crystallization or solidification in the close clearances between the piston and body bore, which could keep the poppet from opening freely. Use only clean, strained (#20 mesh min), or filtered liquids or gases so that the  valve can operate without buildup of debris or solid matter which can cause the valve to malfunction. A basket strainer or high-pressure filter with the appropriate material and pressure rating can be purchased from Stra-Val. Avoid locating the valve where freezing can occur, and if unavoidable, take precautions to insulate or heat wrap valve and piping to keep from freezing.

El sistema OneFlow®+, Serie OFPSYS, es una tecnología de tratamiento del agua física, económica y respetuosa con el medio ambiente, que protege las tuberías, prolonga la vida útil de los aparatos y mejora el sabor del agua mediante su filtración. El sistema OneFlow®+ se compone de dos cartuchos: un cartucho de carbón en bloque de 20 micras con flujo radial que reduce los sedimentos, el olor y el sabor a cloro, y un cartucho integrado OneFlow®+ que previene la formación de cal. El sistema OneFlow®+ utiliza una tecnología innovadora para atraer los minerales disueltos en el agua dura transformándolos en partículas de cristal microscópicas inertes e inofensivas. Estos cristales permanecen suspendidos en el agua y son transportados por ella para su drenaje. El sistema requiere muy poco mantenimiento, no necesita retrolavado y no utiliza electricidad ni sales. Los problemas típicos del agua dura, especialmente la acumulación de incrustaciones en los elementos de calefacción, tuberías, calentadores de agua, calderas y artefactos se reducen. El sistema OneFlow® no es un descalcificador de agua. No requiere productos químicos. Es un sistema que previene la formación de cal que cuenta con datos de ensayos comprobados por un laboratorio independiente y años de exitosas aplicaciones en el sector comercial, residencial y alimentario. OneFlow®+ es la solución inteligente contra la formación de cal y es una excelente alternativa sin sales a los ablandadores de agua (intercambio iónico) o a los descalcificadores. Reduce los sedimentos, el olor y el sabor a cloro. Protección y prevención contra la formación de cal sin necesidad de productos químicos - transforma los minerales presentes en el agua dura en cristales microscópicos inertes e inofensivos, lo que convierte a OneFlow®+ en una alternativa eficaz, sin sales, a los ablandadores de agua de intercambio iónico. Prácticamente no requiere mantenimiento - no se deben añadir ni mantener constantes sales ni otros productos químicos. No requiere válvula de regulación ni electricidad y no genera aguas residuales. Mejora la eficiencia de todos los dispositivos de calentamiento del agua y de las tuberías aguas abajo. Es fácil de instalar - acoplamientos estándar de 1". Es un sistema perfecto para viviendas donde es necesario proteger los equipos a fin de garantizarles una vida útil más larga y obtener un menor consumo de energía. El mantenimiento es sencillo en los sistemas de cartucho OneFlow®+. En el suministro se incluye el soporte de montaje de fácil instalación y una herramienta multifunción para permitir la sustitución del cartucho cuando sea necesario.

First select a size, then the appropriate pressure rating or pressure group. Now a spring range by clicking on the round circles. Then select the proper material for the body #8 and poppet #7 which are the only wetted materials in this valve. Next, select the proper piston seal material #9, which must also be suitable for the media used. The more elastic Buna and Viton & Epdm seals tend to create less of a piston drag than the harder Teflon (PTFE) seal. The softer elastomeric seals produce a much closer band between crack and reseating pressures. Normally viton will handle most solvents, oils and chemicals and can handle most media between 300F to 400 deg F. Next select the Spring chamber #3, spring hardware #1 & #2. The adjusting spring #5 is normally supplied in a chrome silicon steel which is completely protected inside the spring chamber and is not wetted or exposed to the flow media. These are all isolated (non-wetted) from the fluid media and should be selected based on the external environment the valve is exposed to. The carbon steel spring chamber, when selected, is painted on the exterior and interior to withstand normal atmospheric corrosion. After the customized selection is made, click to continue and instructions will be provided to either print or save the selection or to proceed with ordering the item on line. Printing the selection will not commit one to ordering the items selected.

These valves do not carry the Canadian CRN or ASME approval stamp and should not be applied where this requirement must be met. However, the valves generally meet or exceed ASME design criteria with wall thicknesses that are much heavier than the minimums required. For an additional charge, valves can be ordered with material certs and with a certified hydro-test certificate and other tests to meet special documentation and acceptance requirements.

Although the valve is typically installed in the position illustrated, it can operate in any position or orientation, vertical horizontal, etc as long as it can be easily accessed for making adjustments.

These valves are not equipped with a manual lever release. However, manual override is accomplished by first unlocking the spring lock nut to the adjusting screw and backing it out enough to open the poppet to release pressure, and then repositioning it to its original preset locked condition without losing the original set pressure. This procedure is recommended periodically to flush the seat and to check for proper opening of the valve piston.

This is a poppet and spring type relief valve where the spring constantly opposes the pressure acting against the poppet which seals off the inlet port from the outlet port at the valve seat. The desired set pressure or relief is achieved by compressing the spring until the spring force is adequate to balance the pressure force acting against the poppet. When the inlet pressure exceeds the set pressure, the poppet will open to relieve the excess pressure. The valve will operate in a vertical orientation as illustrated, horizontal, or any other orientation.

Scroll down below to select the valve size, spring range, material options in the customized pricing and ordering section indicated by the red arrows. You have the ability to customize your valve choices by selecting the wetted and nonwetted materials, and choice of seat materials to suit your shutoff requirements, using the softer seats for improved shutoff, particularly for air or gas applications where they are available at the lower pressures. Once these selections are made a price quote can be generated and printed directly to your computer or immediately e-mailed to you. When ordering don't forget to state your desired relief set pressure if you expect the valve to relieve at only one pressure. This pressure will be engraved on the valve body. If the set pressure is not specified, the valve will be set at or below the stated spring range as selected for the order and no set pressure will be stamped on the nameplate.

Use these valves for emergency relief where pressures must be relieved quickly to reduce damage that could result from overpressure in a system. Where the overpressure needs to be controlled more gradually ,such as in back pressure or pump bypass applications use our Back-pressure/Bypass valves which will reduce the probability of pressure spikes that often occur when relief valves are selected for pressure control applications. Standard metal seated valves meet ANSI/FCI Class IV seat leakage standards (0.01% of rated valve capacity,  not bubble tight).
