The Sun Hydraulics SQFBMAV (SQFBMAV) is a kickdown sequence valve designed to create an unrestricted flow path from port 1 to port 2 once the pressure at the inlet port 1 exceeds the valve setting. This mechanism ensures that the valve remains open as long as the pressure at port 1 surpasses that of port 2. To reset, the pressure at port 1 must drop below the valve setting, and flow must cease between ports 1 and 2, with pressure at port 2 equal to or greater than that at port 1. Notably, this valve should not be used in load holding applications. It features a protected main stage orifice with a 150-micron stainless steel screen and can handle pressures up to a maximum of 5000 psi (350 bar). The design incorporates Sun's floating style construction, reducing risks of internal binding due to installation torque or machining variations. The SQFBMAV is intended for use on the actuator side of systems; if used on the pump side, pump flow must cease for resetting. It offers a capacity of up to 30 gpm (120 L/min) and has a typical response time of about 25 ms. The valve's leakage is minimal, with a maximum of approximately 3 in\u00b3/min (50 cc/min) under specified conditions. Installation requires specific torques for both the valve and locknut, ensuring secure placement within hydraulic systems. Additionally, it includes an adjustment feature allowing for fine-tuning via clockwise turns to increase settings, accommodating various operational needs in hydraulic applications.
