Product Overview:
The Carraro UBA HHP is a high-pressure, spring-piston loaded, direct‑operated pressure regulator—designed for both pressure reduction and as a relief/back‑pressure valve. Key characteristics include:
- Direct‑acting, spring‑piston design (self‑actuated, no pilot needed)
- Suitable for high pressures (ANSI 2500 rating)
- Can function as a pressure reducer, relief valve, or back‑pressure regulator
- Available in stainless steel (316SS) or Monel construction
- Internal pressure sensing (compact, rugged, minimal installation footprint)
In short, the UBA HHP is a robust, direct-action regulator tailored for demanding applications requiring high inlet pressures.
