Product Questions & Answers (1)

Question by: Dean J on Dec 1, 2025, 4:27 PM
flow adjustment on this valve, can you actually make changes while the system is still under pressure, or do you have to shut things down first?
Answer by: Customer Support on Dec 3, 2025, 11:21 AM
You can make flow adjustments while the system is under pressure. That's one of the practical advantages of this valve. The needle and stem design allows for real-time tuning without needing to depressurize the line first, which saves a lot of time when you're trying to dial things in during operation. Just keep in mind the pressure rating tops out at 2000 PSI, and it's rated for non-shock service only.
