The 8320 Series provides 3‑way (3/2) poppet valves with NPT ports in 1/8″ or 1/4″ sizes. Cv values range from ~0.06 to ~0.25, offering fine control for air, gas, water, or light oil.
Coils support AC (24–480 VAC) and DC (6–240 VDC), with watertight RedHat II housings. Explosion-proof versions are available using the “EF” prefix.
Yes—they require no minimum pressure differential, making them suitable for vacuum and low-pressure systems commonly found in instrumentation and analytical equipment.
The 8320 Series is UL listed, CSA certified, meets CE directives, and certain models are SIL‑3 capable per IEC 61508, ensuring reliable performance in harsh environments.
Absolutely—the valves are designed for universal mounting (horizontal, vertical, or inverted), making them easy to install in complex piping or compact control panels.
These versatile valves are used in analytical instruments, dust collectors, life sciences equipment, press machines, HVAC controls, and metal-stamping systems.
