gmsn safety valve quotation

PLEASE NOTE: As with all vacuum tube based designs, this module is very sensitive to noisy power supplies. Check out this forum post for more info: https://forum.gmsn.co.uk/t/safety-valve-noise-problems/355

A pressure Relief Valve is a safety device designed to protect a pressurized vessel or system during an overpressure event. Our relief valves help to protect downstream equipment or control the upstream pressure of gas or liquid.

-It is designed for the 12ax7 tube to be soldered straight to the board without a socket to save excessive height. in this module provided you don’t chuck it off a balcony the valve will be fine, in this design it is also running cold so you wont have any worries of it prematurely breaking. It will last just as long if not longer than other components in the module.

-The valve also doesn’t even have to be soldered to function, if your feeling fancy look closely at the module in the above images you will notice i didn’t solder the valve in, the PCB actually holds onto the valve enough to provide sufficient contact, nearly as much as a socket would anyway! I am not sure how this will change over time, but for not it works fine. However if you want reliable and worry free use i would recommend to just solder it on down and forget about it.

-Touching the valve? This is a bit of a myth in respects to the fact that yes in some high temperature high reliability applications valves don’t want to be touched as over time the grease may indeed weaken the glass. But for general use and general purpose valves like the 12ax7 its completely negligible. in-fact this tube in this application doesn’t even get as hot as a cup of PG tips. So dont worry about it.

-Status LED! try to get a super bright 3mm LED, it will really make the tube illuminate as the heater filament in this application does not glow much if at all. In theory! a Bi Coloured LED would work too! Dont poke the LED all the way through the hole, just enough so that it is flush with the pcb, this means you can seat the valve right down to the PCB.

You might encounter a dealer who promises magic in your tires in the form of color-changing valve stems that change from green to red when your tires need air, all for the low price of between $40-$100 for a set of four. First of all, most new — or newish, even — cars come with low-tire-pressure indicators on the dashboard. Even if yours doesn’t, the two tools that have worked for time immemorial — your eyes and a pressure gauge — will serve the exact same purpose.

One of two surgeons associated with Baxter Regional Heart and Vascular Clinic, Dr. Munns’ primary specialties are cardiovascular and thoracic surgery. The other surgeon, Kent Nachtigal, specializes in vascular surgery. Also in the practice are Kathleen Prinner, MSN, APRN, ACNS-BC, NE, and Emily Brown, MSN, APRN, FNP-C. Most of Dr. Munns surgeries, about 75% he says, are cardiac with the remainder being thoracic. He is a specialist in transcatheter aortic valve replacement surgery (TAVR), a state-of-the-art, minimally invasive procedure. During his career as a cardiovascular surgeon, he has performed over 700 TAVR procedures. At Baxter Health, Dr. Munns and Dr. Akihiro Kobayashi, a structural cardiologist, perform TAVR surgeries together. “TAVR is not something you typically find in a hospital the size of Baxter Health,” said Kimberly Foxworthy, MSN, RN, structural heart coordinator at Baxter Health.
