Function and usage:

These valves are used to control flow in one direction. In the other direction, the flow is free. The quantity of oil depends on the oil pressure, temperature and viscosity. These valves do not have a pressure compensator.

Material and characteristics:

Body: galvanized steel
Inner parts: hardened and ground steel
Seals: BUNAN standard
Tightness: Depending on the size, minimum leaks of the closed valve
Controller: plastic


Connect V to the pressure source and C to the appliance. The flow is adjustable in the C to V direction and free in the reverse direction. The flow is set by rotating the plastic controller after the side bolt is released. This arrangement allows precise and fine adjustment.
