Reject Valve FAQ
What is the typical lifespan of a reject valve?
The lifespan of a reject valve depends on operating conditions and maintenance. Under normal conditions with proper maintenance, our reject valves typically last 5-7 years in continuous service. Extreme conditions may reduce this lifespan, while optimal conditions with regular maintenance can extend it beyond 10 years.
How often should a reject valve be inspected?
We recommend quarterly inspections for reject valves in standard applications. For critical applications or harsh environments, monthly inspections are advised. Key inspection points include checking for leaks, verifying proper operation, and examining wear on sealing surfaces.
Can your reject valves handle corrosive fluids?
Yes, we offer special alloy reject valves specifically designed for corrosive applications. These models feature enhanced material compositions that resist chemical attack while maintaining structural integrity. Please consult our chemical compatibility chart for specific fluid resistance information.
