PN-J200 is a non-contact injection valve developed by Shizong, which is driven by air pressure and precisely controlled by an solenoid valve. It is suitable for non-contact injection dispensing of low and medium viscosity fluids.

The PN-N100 series is a contact dispensing valve developed by Saejong that utilizes air pressure as its driving force, making it ideal for precise dispensing of low to medium viscosity fluids.

The PN-N601/602 is a rotary contact dispensing valve developed by Saejong, specifically designed for specialized marking applications and precise inner hole sidewall dispensing of low to medium viscosity fluids.
