NOTE: DATA MAY VARY BY CONFIGURATION. SEE CONFIGURATION SECTION.

Three-port normally closed modulating elements with relief provide two functions when combined with an external

orifice. The mainstage is a bypass compensator that controls a priority flow into the circuit, determined by the

external orifice. Input flow in excess of the priority flow is bypassed to tank (port 2). If the inlet (port 1) pressure

rises to the valve setting, the valve operates as a normal relief valve.

TECHNICAL FEATURES

Compensating pressure for the A range is 45 psi (3 bar), for the B range 30 psi (2 bar), and for the C range 100 psi (7 bar).

Explanation of the performance curve: The X axis is system pressure. The Y axis shows the pressure differential that the valve creates across the control orifice.

The curves represent various bypass flows (pump flow minus control flow). The capacity and performance of this valve is determined by the bypass flow, control

flow is not a factor.
