Technical Feature
OPERATION:
Kick-down sequence valves 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 ① to 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 ① to ② must cease; pressure at port ② must be equal to or
greater than the pressure at port ①．FEATURES：
• Should not be used in load holding applications.
• The main stage orifice is protected by a 150 micron stainless steel screen.
• 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. -
