Flow Control

820185719 - FLOW REGULATOR - VRC 12-EN-5.00-00 - DANFOSS
Flow Control, Partially Adjustable, Pressure Compensated, Priority Type
315 bar [4600 psi] • 73 l/min [19 US gpm]
DESCRIPTION AND OPERATION
This is a partially adjustable, priority type, pressure compensated flow control valve, where the flow from port 3 will remain constant regardless of the pressure difference across the valve, while excess flow passes from port 1 to 2. Flow enters at port 1 and passes across a fixed orifice in the spool, which creates a pressure drop. This causes the spool to move back against the spring, which then restricts the outlet flow. Port 1 then opens to port 2 to allow excess flow to pass. The regulated flow will always take priority and remains constant if the working pressure is higher in either port 2 or port 3.

Needle Valve, Fully Adjustable with Reverse Free Flow
210 bar [3000 psi] • 45 l/min [12 US gpm]
DESCRIPTION AND OPERATION
This is a needle valve with a reverse free flow check. It is a variable orifice used to create a pressure drop when flow passes from port 2 to 1, while allowing free flow when flow passes from 1 to 2. Clockwise rotation of the adjustment screw decreases the flow setting until it is completely closed. The setting can be locked by tightening lock nut or knob on the adjustment screw
