FRRV12-41F Priority Flow Regulator . . . (FRRV12-41F)
A screw-in, cartridge-style, multi-function valve which includes a fixed-compensated, priority-type flow regulator and an adjustable pressure relief valve in one cartridge.
Product Operation
The FRRV12-41F maintains a constant flow rate from port ➂ regardless of load pressure changes at priority port ➂ or bypass port ➁. When load pressure at ➂ reaches the setting of the relief valve, flow is dumped over the relief at ➃. The exit flow from the relief can be connected to tank or to the bypass flow.
Note: Back pressure at port ➃ is directly additive to the relief setting.
Product Features
• Two valve functions in one, industry-common cavity.
• Adjustments cannot be backed out of the valve.
• Relief valve adjustments prohibit relief valve spring from going solid.
• Quiet, modulated response.
• Hardened parts for long life.
