Questions about this item

Does the 316 stainless-steel disc need periodic replacement under normal service?

The 316 stainless-steel disc is designed for long service life; replacement is only required if inspection shows wear, corrosion or seat leakage.

What pressure limit activates the valve first during a sustained over-pressure event?

The factory-set pressure of 50 psig is the first limit that causes the valve to open.

How much heat does the valve dissipate when it relieves at 50 psig for extended periods?

The valve body is rated from -320 °F to 800 °F, so it handles relieving temperatures within that range without additional cooling.
