High-Pressure Hydraulic Ball Valves | DIN, BSP, NPT & SAE Connections
As a leading China professional manufacturer of high-pressure fluid connectors, Fitsch (Ningbo) International Trade Co., Ltd. engineered these premium high pressure hydraulic ball valves to deliver leak-free, zero-drop isolation performance within demanding industrial, mobile, and oil-field machinery networks.
Designed as durable 2-way directional shut-off devices, our block body configurations handle working pressures scaling up to 500 bar (7,250 PSI). By machining every valve block inside our state-of-the-art facility featuring 200+ precision CNC stations, we maintain rigid quality consistency to provide a reliable structural swap for traditional high-pressure control valves.
⚙️ Multi-Standard Global Connection Profiles
To guarantee seamless drop-in integration across global machinery builds, our product line encompasses four crucial international mounting formats:
DIN 2353 (ISO 8434-1): 24° cone cutting ring tube connections available in Light (L) and Heavy (S) pressure configurations.
ISO 1179-1 (Female BSP): Threaded ports equipped with O-ring sealing recesses to safely block high-pressure system reverse lines.
SAE 476 NPT / ANSI B1.20.1: Precision tapered threads offering tight, mechanically locked seals for global fluid lines.
SAE J518 (ISO 6162-1 / 6162-2): Code 61 (3000 PSI) and Code 62 (6000 PSI) split flange port structures built for extreme shock loads.

Key Functional Advantages
Full-Bore Flow Alignment: Minimizes internal pressure drops and fluid turbulence when the valve arm shifts to a full-flow path.
Blow-Out Proof Stem: Deep-seat safety architecture withstands sudden pressure spikes without structural ejection.
Premium Surface Passivation: Our zinc-nickel electroplating process offers over 720 hours of salt spray resistance to counter external corrosion.
Mass Manufacturing Agility: Fitsch outputs up to 1,500,000 components monthly, allowing us to supply large wholesale runs with short lead times.
