Function and usage:

These valves are used to control flow in both directions. The quantity of oil depends on the oil pressure, temperature and viscosity. These valves do not have a pressure compensator.

Material and characteristic:

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


Connect V to the pressure source and C to the appliance. The flow is controlled by turning the external ring, clockwise to increase the flow and vice versa to control the flow. When the flow rate is set, the valve is locked in the required position by contra nut.
