Safecastle: owned & operated since 2002 by your
 Victor Rantala
M. Brooks, 1/20/12: "I figured the 'lifetime membership' offer was too good to be true ... I began to order products and am absolutely amazed! The service is incredible; each time I have contacted Mr. Vic, I get an immediate response. He has always been kind and considerate and very professional and stands behind his word. The membership perks are phenomenal. Because we are at such a critical juncture in our world, preparedness has become big business and there are a lot of folks in it just for the money and provide substandard products and services. I believe Safecastle is really a ministry to those trying to prepare ... It is truly a first rate outfit, selling quality products at a reasonable price, owned and operated by a man who has a servant’s heart."

Blast Valve
|
Item Number: 00106
|
This blast valve is designed and tested to protect an underground shelter from a 50 pound per square inch detonation.
In order to withstand this incredible pressure, this item is fabricated from 3/8" (.375 inch) steel. It is a heavy, robust item designed to keep the massive pressures of a nearby conventional or nuclear blast from injuring or killing the occupants of your bomb shelter.
The ARS-50-BV Automatic Double Acting Blast Valve automatically closes when the initial positive pressure wave from an explosion hits and automatically closes a second time (in the other direction) when the outside air pressure goes negative in relationship to the internal shelter pressure. When the outside air pressure returns to normal, the blast valve automatically returns to its normally open state. In other words, it lets air flow into your Safe Cell or out of your exhaust port for normal operation, but will not allow a blast of high-pressure air to enter your shelter - and bring contaminants with it.
These valves are only necessary in hardened bomb shelters and should be used in pairs - one on the air intake pipe and one on the air outflow pipe. |
