Features

Benefits

Quick-Acting Design

90° quarter-turn operation for fast pig launch/receive, minimizing pipeline shutdown time.

Full-Bore Access

Unobstructed flow path matches pipeline ID, ensuring pigs pass smoothly without snagging.

Dual Isolation Seals

Primary and backup seats prevent pressure loss during pigging; bubble-tight per API 598 Class VI.

Abrasion-Resistant Trim

Stellite®-faced seats and hardened alloy balls/plugs withstand pig contact and gritty media (sand, wax).

Integral Bleed Port

Safely depressurizes the pig chamber before opening, critical for hazardous service (hydrocarbons, H₂S).
