The Hyvair FC20-4FP is an in-line flow control valve with 1/4 in female NPT ports, part of the FC20 Series. It meters flow in one direction and lets oil return freely in the other, which makes it a simple way to control actuator speed.
An integral check valve with a 2 psi cracking pressure handles the free-flow direction. In the controlled direction, the valve meters flow for speed control and system tuning. Rated Cv is 0.47 in the controlled direction and 1.47 in free flow.
The body is steel and the valve is rated to 5000 psi. Maximum temperature is 400°F (200°C) at a minimum fluid viscosity of 80 SUS. It is recommended for petroleum-based fluids in the ISO VG32 to 68 range.
The valve is compact: 13/16 in square and 2-5/8 in long, with a 1-3/8 in maximum envelope. A color band on the body identifies it, which speeds up maintenance and inventory checks. Typical uses include cylinder speed control and general hydraulic circuits where one inline valve should handle both metering and free return flow.
