diaphragm safety valve in stock

First select a size, then a spring range. Since the Body #8, contains the pressure, select the proper material that is suitable for the fluid or gas used. Next, select the proper diaphragm material #7, which must also be suitable for the media used. The more elastic Buna and Viton Diaphragms tend to seal off better than the harder Teflon (PTFE) diaphragms. Then select the Spring chamber #3, spring hardware #4 & #6, and the adjusting spring #5. 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. When an aluminum or PVC spring chamber is selected, the internal spring hardware #4 & #6 will be the same material as the spring chamber #3, and the external hardware (adjusting screw #1and lock nut #2) will be a 300 series stainless steel. 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. Should you have any questions on the product capability or product options, or are having difficulty in making the pricing selections or ordering, please contact us by e-mail or phone between 9AM-5PM Eastern time, Monday-Friday. Please note that in most cases the pricing on our In-Line ported model RVi20 may be less expensive than the RVL20 (angle ported model) shown in the pricing table below, for which we also carry more stock in the smaller sizes, resulting ususally in faster deliveries.

This safety relief valve can be used for relieving pressures and maintaining upstream line pressures to a specific set pressure. Pressure relief valve can also be used for bypassing fluids or gases. Only strained or filtered liquids are recommended. When liquids contain debris or other solid matter which might cause the valve seat not to close properly with this type of pressure relief valve, a low-pressure strainer with a fine wire mesh should be installed before the inlet of the valve. Simplex basket strainers or low-pressure filters can be purchased from Stra-Val. This is a diaphragm low-pressure valve which is used where accurate set pressures must be maintained. The large diaphragm area compared to a piston pressure relief valve produces much more accurate pressure control with very low hysteresis between opening and closing pressures.

Right-angle porting: Side inlet, bottom outlet is standard with this diaphragm valve manufacturer’s model. Take a look at our in-line ported diaphragm valve which is usually the more preferred piping arrangement that we generally stock, so deliveries are shorter, and are also usually priced less. Special threads or ANSI and sanitary flanges (tri-clamp flanges) are also available.

The Hayward RPV Series Pressure Relief valves protect sensitive process equipment from over-pressure situations by maintaining target operating pressure. The RPV Series pressure relief valves are available from 1/4 to 4", with PVC, CPVC, PP and PVDF wetted bodies. The factory set pressure of 50 psi is easily field adjustable between 10 to 150 psi (other pressure ranges are available by request). Backed by Hayward"s 3-year warranty, the RPV Series Pressure Relief valves will provide reliable results in your tough Chemfeed applications.

For sealed heating systems as per TRD 721; VdTÜV sheet Safety Valve 100 and 100/4 sheet 1; EN 12828. Also for water heating systems as per DIN 4751-2 with flow temperatures up to 120 °C and DIN 4751-3 with flow temperatures up to 95 °C. Suitable for water, water/glycol mixtures (max. 50 % glycol) and liquids of fluid groups 1 and 2 (Pressure Equipment Directive, Art. 9).

It uses a diaphragm structure with only highly inert wetted materials such as PTFE, PPS, and FFKM and can handle severe media with strong acids and strong alkalis.

The valve opens, and the media flows to the secondary port when the primary pressure exceeds the relief pressure, preventing the flow channel from rising further.
