The supplies and chemicals specified within the experiments were, of course, intended to be a set of "easily obtainable" materials. However, the set of materials that might be described that way has changed greatly over the last half century. You might understand if a few of them are simply (or practically) unavailable in the modern era. One of the motivations for this annotated edition is to make the book more usable by filling in these gaps with modern sources and (in some cases) modern substitutes. Some of the materials are genuinely hazardous and rarely used (by individuals) for reasons of safety. Substances such as mercury and asbestos are still legal and in widespread industrial use, but have either been banned or fallen out of favor in many of their former applications. Kitchen potholders are no longer lined with asbestos, and oral thermometers are more likely to be digital than mercury-filled. And that is not a bad thing. In the one place where asbestos actually comes up in the book — an asbestos tile to protect your desk from hot glassware — we recommend that you use a regular kitchen trivet instead.

Some other materials are no longer produced (at least in quantity), for example, vacuum tubes for radios. And some other materials that are hard to purchase without appropriate credentials. Many chemical supply companies will only sell to institutions or approved companies. As an independent or amateur scientist, nothing could be more frustrating. We will endeavor to provide alternate sources or substitutes when barriers like these might become issues. This table is a living resource, that we are currently updating, and will continue to update with links and sources for purchasing the individual materials. (We are working on allowing reader-contributed sourcing notes as well.) Please see the bottom of the page for the meanings of abbreviations that are used.Rain Bird manufactures only the highest quality valves. Use DV/DVF series valves in locations where the use of a separate pressure vacuum breaker (PVB) or a double-check valve is required by city codes to protect against back flow.

Check your local city codes to determine what type of valves are required. All of our valves work with any standard sprinkler timer. Double-filtered pilot-flow design for maximum reliability. Balanced-pressure diaphragm for long life. External bleed to manually flush system of dirt and debris during installation and system start-up. Internal bleed for spray-free manual operation. Energy-efficient, low-power encapsulated solenoid with captured plunger and 90-mesh (200 micron) solenoid filter. Buna-N diaphragm with self-cleaning 90 mesh (200 micron) pilot water filter and captive spring. Operates in low-flow and Xerigation® applications when the RBY filter is installed upstream. 1.25" (3,2 cm) stainless steel phillips head screws. Accepts latching solenoid for use with Rain Bird battery-operated controllers. 3/4" (20/27) and 1" (26/34) standard in-line configuration. 1" (26/34) Slip-by-Slip (SS) configuration for low cost, solvent-weld installations.

1" (26/34) Angle (A) configurations for flexible installations especially when submains are deep. 1" (26/34) Male-by-Male (MM) thread configuration for quick and easy manifolding. 1" (26/34) Male-by-Barb (MB) male thread inlet by barb outlet configuration for installation with poly pipe. Unique, easy-to-turn patented pressure assisted flow control mechanism (DVF models only).dyson vacuum cleaner brushes *Available with BSP threads.dust vacuum cleaner hire Rain Bird recommends flow rates in the supply line not to exceed 7.5 ft./sec. (2,3 m/s) in order to reduce the effects of water hammer.funny vacuum cleaner stories DV Series valves cannot be used with PRS pressure regulating modules.

Pressure: 15 to 150 psi (1,0 to 10,4 bar) 075-DV Flow: 0.2 to 22 GPM (0,05 to 5,0 m3/h; 0,01 to 1,39 l/s). For flows below 3 GPM (0,75 m3/h; 0,21 l/s) or any Xerigation® application, use a 200 mesh filter installed upstream. 100-DV Flow): 0.2 to 40 GPM (0,05 to 9,08 m3/h; 0,01 to 2,52 l/s). 100-DVF Flow (non-union): 0.2 to 40 gpm (0,75 m3/h; 0,21 l/s); for flows below 3 gpm or any Xerigation application, use a 200 mesh filter installed upstream.
