Ideal for dry material handling with successful applications in industries around the world. The robust design of the H-Series is the perfect selection for large volume, large particle sizes, and the most demanding conditions. Rated for up to 40 PSI (2.75 Bar) and temperatures up to 1800F/980C.Learn More
Same features of the H-Series with an air tight radial (round) opening with round internal mating components (seat/flapper). This valve received its name based on its round (radial) opening. Rated for up to 40 PSI (2.75 Bar) and temperatures up to 1800F/980C.Learn More
Same rugged design as our famous H-Series Flap Valve at roughly half the height for applications when headroom is restricted. This valve is named for its “S”horter profile than our original H-Series. Rated for up to 15 PSI (1.0 Bar) and temperatures up to 1800F/980C.Learn More
The perfect valve for pollution control systems and other low pressure differential (< 2 psi/.14 bar) applications, with the same profile as the S8-Series. Rated for up to 750F/400C.Learn More
