Is the exhaust valve on the reciprocating machine constantly leaking?

Is the exhaust valve on the reciprocating machine constantly leaking? Leaks occur frequently, mostly after the reciprocating machine is switched over. What’s going on? How to deal with it? The sealing ring is made of nitrile.
Reply 1# lostch: Does the exhaust valve also leak before switching to the reciprocating machine? It should be a fault with the exhaust valve. There are many reasons for failures in exhaust valves; I’ll mention a few: 1. The valve disc and seat are not sealed properly. The 2 valve seat bolts are not tight. The 3-valve assembly is not airtight at the cylinder seat fitting. 4 valve plates are warped and deformed. 5 Improper assembly. 6. Issues related to the mass of the exhaust valve itself. Damage to 7 valve plates. The elasticity of the 8-valve spring is inappropriate. 9 Liquid slugs, impurities, carbon deposits, etc. Solution: Only the exhaust valve needs to be replaced. If something is not covered, please add it downstairs.
Is the sealing ring made of nitrile? ? I don’t understand; please explain. All compressors we deal with are made of metal (there are aluminum gaskets, copper gaskets, and steel gaskets),; we’ve just never seen yours. We would appreciate your advice so that we can exchange information.
1. Severe carbon deposition on the air valve. 2. More gelatinous substances accumulate and bind together. 3. Use nitrogen to displace the air as much as possible when in standby mode.
Reply 1# lostch Nitrile rubber easily fails when exposed to high temperatures and alternating stresses over a long period of time. It is recommended to replace it with an aluminum pad.
