Marchesini VSQAPP sequence valve, insensitive to back pressure, 3/8" to 3/4", also with handknob.
The VSQAPP runs two actuators in order of pressure, like the VS2C, but it is not sensitive to back pressure: the pressure set in the circuit is used to drive both actuators instead of adding up. When the pressure at V reaches the spring setting, the valve opens to C; from C to V the return is free through the built-in check valve.
Maximum pressure 250 bar on the 3/8" and 1/2" sizes. Springs available: 10-50, 20-100, 10-180 (standard), 50-250 and 80-300 bar. The /V version has a handknob for adjustment by hand, without tools.
