The regulator in my Avenger .25 takes an excessively long time to refill-20 to 25 seconds. What could be the cause of this and is there a way to correct it to get a speedier refill?
It's a new rifle so the reg seal should not be worn. Set point is 2100 psi. I will try to check the orifice for problems. Thanks.Slow recovery can be a symptom of:
I am not aware of a mechanism by which polishing the Belleville washers will remedy slow recovery.
- Wear of the seal at the end of the piston, and/or...
- Scratch or machining marks on the orifice (seat), and/or...
- Debris trapped in the orifice
- Setpoint too close to the top end of the adjustment range (Belleville spring washers nearly flattened such that the seat can barely open)
The most common issue relates to the first two bullet points. What happens is the seat quickly reaches an almost closed state but air continues to eek through voids or scratches over period of seconds or minutes until the pressure finally climbs high enough to totally squeeze it closed.
Inspect both mating surfaces of the valve seat with the aid of magnification. If the plastic part is dented badly or has little wispy plastic fibers in and around the indentation, it needs to be either replaced or wet sanded flat and smooth. If the other surface, usually a raised cone, has machining marks or a burr, carefully dress it as well. Meaning just the truncated end of the cone...the part that meets to the plastic seal.
