The VBF6 are adjustable bidirectional flow control valves. The flow restriction therefore occurs in both directions of the valve crossing. The valve is not compensated: the set opening value therefore corresponds to a variable flow rate depending on the pressure drops present across the valve. By inserting a hydraulic compensator inside the circuit, a constant flow regulation system independent of load variations can be obtained. The valve can be used as an ON / OFF tap. The VBF6 flow control valves can be installed in 2-way cavities dimensioned according to the SAE08 standard (3/4-16 UNF thread). The maximum working pressure for the flow restrictor VBF6 is 350 bar, while its use is recommended with inlet flow up to 40 l / min. The valve opening adjustment is by screw in the standard configuration; the regulation with a graduated hand knob is available as option. All the valve’s components are made of high-resistance steel and the external components are protected from the action of corrosive agents by zinc plating treatment.
