Key Features & Benefits
- Preset 150 PSI relief — lifts automatically once tank pressure exceeds the set point — no adjustment needed.
- Pop-off action — snaps open to dump excess pressure fast, then reseats as pressure falls back to safe levels.
- 1/2″ connection — threads into the safety-valve boss on common air-receiver tanks.
- Essential tank protection — the last line of defence if a pressure switch or unloader fails — required safety fitment on a pressure vessel.
When to Use This Valve
Reach for part COSSV1/210BAR to fit or replace the safety valve on a compressor receiver rated to 150 PSI. It is a mandatory protective device — never plug, blank off or override it. Test it occasionally by lifting the ring to confirm it lifts and reseats freely.
Pro Tip: Match the valve’s set pressure to your tank’s rating, not just your working pressure — the safety valve must lift below the receiver’s maximum rated pressure to actually protect it.
