Operating Pressure 350BAR
Internal Leakage 30ml/min.max.at operating pressure
Temperature -30°C to +120°C(-22°F to+250°F)
Cavity T-11A see page K-2
Fluids Mineral-based fluids with viscosities of 7.4 to 420 cSt.
The main stage orifice is protected by a 150 micron stainless steel
Pressure at port 3 is directly additive to the valve setting at a 1:1
ratio and should not exceed 5000 psi (350 bar)
Intended for use on the actuator side of the system as flow through
the valve must cease for the valve to reset. If used on the pump side
of a system, pump flow must be shut off for the valve to reset.
Kick-down sequence Valve will kick completely open and remain open
once the pressure at the inlet (port 1) exceeds the valve setting, creating an
unrestricted flow path from port 1 to port 2 (sequence). The pressure
setting at port 1 is relative to the drain (port 3). The valve remains open as
long as the pressure at port 1 exceeds the pressure at port 2. To reset the
valve, pressure at port 1 must fall below the setting of the valve, flow from
port 1 to port 2 must cease, and pressure at port 2 must be equal to or
greater than the pressure at port 1.
