SMALL DIAMETER BALL VALVE

Compact, forged 1/2″, 3/4″, and 1″ ball valves rated 4,000 psi WOG with FNPT ends and ISO 5211 mounting for easy automation. Fire-safe to API 607, sour-service trims per NACE MR0175/ISO 15156, and temperature rated –50°F to +250°F (standard materials). Offered in Sour/Low-Temp and 316 Stainless trim options.

PRODUCT OVERVIEW

Argus Small Diameter Ball Valves are forged for strength and long service life, then validated to leading valve standards. Designs include blowout-preventative stems, antistatic paths, and low-torque operation. O-ring stem sealing eliminates packing adjustments, reducing maintenance. Seat geometry maintains sealing at both high and low ends of the pressure rating. A locking device supports LOTO procedures. Automation is simple via the ISO 5211 pad.
