Pigs Unlimited International, Inc.’s PU-2 Pigging Valve series offers an economical alternative to conventional launchers and receivers. They are capable of launching and receiving foam, steel, and solid-cast pigs in both cylindrical and spherical shapes. For use as end-of-line units or within inline closed-loop systems, the design incorporates a one-piece body and flange assembly. This ensures complete integrity throughout the entire valve.
Consisting of a trunion-mounted ball, it is equipped with true block-and-bleed capabilities. The proven shut-off style design allows for energizing an upstream sealing seat for maximum sealing capabilities. The ball and stem are constructed of 300 series stainless steel, with blowout-proof stem, and two bleed connections for venting the pressure before accessing pig chamber. Also, all repairs can be made in the field without having to remove them from the line. The units are bi-directional and able to serve as both launcher and receiver.
Available in an unlimited size range of 2” and up, and in ANSI ratings of 150 to 1500, with construction materials of carbon steel, stainless steel and various exotic alloys, the PU-2 Pigging Valve can be manufactured to be compatible with your specific pigging needs, offering a safe, economical alternative to conventional launchers and receivers.
