|3/4/5 Port Solenoid Valves

Can a VQ7-□-FPG perfect valve hold a cylinder at an intermediate position longer than a VQ7-□-FHG (metal seal)?

The VQ7-□-FPG perfect valve is a valve in which a perfect spacer (VV71-FPG/VV72-FPG) with a pilot check valve function is inserted between the exhaust center and the base. Although it can hold the cylinder at an intermediate position for longer than the type with a closed center (metal seal), with the perfect valve, it cannot be guaranteed that the position will not deviate.
Note) If there is air leakage from the cylinder or piping, even the perfect valve position will deviate quickly.
