In order to vary the flow of the fluid, the full range pressure compensating varies as the lever is rotated. It has compensator spool inside the valve body. No matter how the pressure varies, that is, no matter the orifice area varies from closed to open, the outlet flows will be constant and stable.
Instruction of full range pressure compensating variable flow control valve with diamond honed spool bore:
The adjustable ball spring relief valve(R) allow the customer pressure compensated flow up to the pressure setting on the relief setting, the relief valve opens and diverts flow to the EX port while maintaining the pressure on the CF port.
The EX port must be plumbed back to tank. The relief option is present to11Mpa(110bar), standard, and field adjustable from 0.5Mpa(5bar) to20Mpa(200bar).
Model description of FC series full range pressure compensating variable flow control valve
Features of FC series full range pressure compensating variable flow control valve:
Diamond honed spool bore provides consistent spool fit with low leakage.
Every FC is tested for shut off, max, flow, and pressure compensation.
Standard thread copmpensator plugs to eliminate external leakage from the compensator bore.
External seals on rotary spool prevents contamination from locking up spool.
