 Instant Response even at low pressures!
Now, you can protect vessel and building contents more effectively, and put an end to expensive, single-use explosion vent and rupture disk replacement costs at the same time.
By installing PSD explosion relief doors, you eliminate the time and cost of membrane replacement forever. Unlike single-use metal vents, PSD gives you a real door. A door that maintains a positive seal until it opens, under precise and predetermined pressure conditions. A door that, once opened, remains open until you close it- with little force and no tools
Patented latching system provides improved performance.
The key to the PSD explosion relief door is a unique diaphragm action, which triggers the magnetic latching system (United States Patent 4,207,706, other pats. pend.). Built directly into the door itself , the latching assembly opens as soon as the preset pressure is reached.
 Other design and manufacturing features include:
- service up to 500 degrees farenheit.
- stainless steel latch springs and hardware.
- nylon sleeves on all critical moving parts to ensure reliable reaction.
- frames can be welded or bolted (4" centers) to housing or vessel.
- fingertip manual release.
- gasket seals for a variety of atmospheres.
- self-leveling latch seals.
