Normally closed modulating element valve with relief function
SERIES 2 / CAPACITY: 80 L/min. / CAVITY: T-2A
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 all ranges is 120 psi (8 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.
W and Y controls (where applicable) can be specified with or without a special setting. When no special setting is specified, the valve is adjustable throughout its full
range using the W or Y control. When a special setting is specified, this setting represents the maximum setting of the valve.
