The 2Q series pneumatic valve is completely pneumatical. There's a pneumatic cylinder on the valve body and control the valve on/off. The valve body is big with orifice size 22mm and 50mm, and we only have 2 thread sizes for the valve, 2-1/8" and 2-1/4". The pneumatic valve is better for some places not suitable for electricity.
