FAQ

Q: What is the difference between Discus and standard reed valve plates?
A: Discus valves use a circular poppet design that provides better gas flow efficiency, lower re-expansion losses, and higher volumetric efficiency compared to traditional reed valves.

Q: Does this set include both suction and discharge plates?
A: Yes, each set includes matched suction and discharge valve plates along with associated springs and retainers.

Q: What is the typical service life?
A: Under normal operating conditions with proper maintenance, these valve plates typically last 15,000-25,000 operating hours.
