A screw-in, cartridge-style, fi xed orifice, pressure-compensated, bypass-type hydraulic flow regulating valve, with limited range adjustment from a pre-determined nominal setting.
The FR10-30A maintains a constant flow rate from ➂ regardless of load pressure changes in the system downstream of ➂, or in the bypass leg at ➁The valve will pressure-compensate once a minimum pressure drop (determined
by spring adjustment setting) is achieved from ➀ to ➂. This value will range from approximately 4.8 to 13.8 bar (70 to 200 psid).
The cartridge may be adjusted to ±25% of nominal setting. At nominal setting,
pressure drop is approximately 9 bar (130 psid).
Flow out of priority port ➂ may vary based on input flow amount, particularly with lower temperatures and increased fl uid viscosities. Settings may need to be
established through correlation study. Consult factory.
• Bypass port ➁ may be fully pressurized.
• Hardened steel parts for long life.
• Quiet, modulated response.
• Industry common cavity.
Operating Pressure: 207 bar (3000 psi)
Customer-Specifi ed Standard Flow Setting: Low Range: 1.9 to 9.5 lpm (0.5 to 2.5 gpm); Specify in 1.9 lpm (0.5 gpm) increments. High Range: 11.4 to 22.7 lpm (3.0 to 6.0 gpm); Specify in 3.8 lpm (1 gpm) increments. See ordering table on facing page. Pressure at ➀ begins to rise higher than compensating pressure differential when bypass flow exceeds 23 lpm (6 gpm).
