DN100 / 4" to DN1200 / 48"

-196°C / -320°F to 950°C / 1,742°F

PN16/25/40/64/100/160/250

ANSI 300/600/900/1500/2500

For large steam turbines and compressors. The inclined cone seal system prevents jamming, provides positive shut off, and has a long life with low maintenance.

​

DN150 / 6" to DN1050 / 42"

Steam up to 550°C / 1,025°F

PN10/16/25/40/64/100

ANSI 150/300/600/900

Designed for steam & gas turbine protection against backflows.  Accomplished by a free swing model that closes automatically by its own weight. This is a robust cast valve with butt welded ends, that can be adapted with flanges. The chrome disc can be replaced via assembly opening. 

DN500 / 20" to DN3000 / 120"

-50°C / -58°F to 200°C / 392°F

PN2,5/6/10/16/25/40

ANSI 150/300

For high pressure pipelines & large diameters. Provides adjustable dampers & timing rate, & can be tuned to match closing for pump specs.
