Features
- A screw-in, cartridge-style, adjustable orifice, pressure-compensted, manually-operated,bypass-type hydraulic flow regulating valve .It can be used as a priority-type flow regulator or a restrictive-type 2-way flow regulator when the bypass port is blocked.
- The VF maintains a constant flow 3 rate from regardless of load pressure changes in the system downstream of 3, or in the bypass leg at 2. Reverse flow ( 3 to 1 ) bypasses the control orifice
- The regulated flow increases form closed to fully open, with counter-clockwise rotation of the knob.
- Note: When used as a bypass flow control in applications where the priority flow port will be blocked by external valving, bypass pressure drop will increase unless a small amount of leakage is provided for the priority port.
