Stauff RV-20-07-N Hydraulic Valve

Stauff RV-20-07-N is a heavy‑duty hydraulic check valve (non‑return) in the STAUFF RV series, engineered to prevent reverse flow in high‑pressure hydraulic circuits. It features a DN20 size with a 1 NPT threaded connection and is rated for a maximum working pressure of 7250 psi (500 bar). The valve opens to forward flow at a cracking pressure of 7 psi (0.5 bar), delivering dependable one‑way operation in demanding systems. Manufactured from mild steel with a zinc/iron plating finish, it offers robust durability and corrosion resistance for hydraulic manifolds, monoblock assemblies, and other high‑pressure routing applications. In service, this RV‑20 component helps protect pumps and downstream components by maintaining directional flow and stabilizing pressure zones where backflow could cause damage or loss of control. The RV‑20‑07‑N designation identifies the DN20 connection with a 1 NPT thread, aligning with STAUFF’s documented RV‑20 size and performance specifications.
