DeZURIK: Metal Cutting Knife Gate Valve

DeZURIK Metal Cutting Knife Gate ValveA new Knife Gate Valve with an innovative metal cutting design has been announced by DeZURIK, Inc. Based on the company’s highly successful KGC series knife gate valves, the new KGC-MC Metal Cutting Cast Stainless Steel Knife Gate Valves are designed to provide long service life in applications requiring shearing capabilities like those found in Pulp and Paper Recycle and Rejects Cyclone applications. Wires, staples, glass or plastic are cleanly cut, crushed and cleared from the seating area.

The KGC-MC valve cuts through the media flow with no jamming problems. To withstand the high loads necessary to shear wires, staples or glass, the valves have a replaceable, serrated seat constructed of 410 Stainless Steel. The seat ring’s teeth and teeth arrangement are designed to prevent bunching or clogging while cutting through heavy trash. Oversized gate guides provide support for the moving gate through the full stroke, minimizing any chance of deflection.

The KGC-MC Knife Gate Valves are available in 3-24" (80-600mm) sizes with onepiece cast stainless steel bodies. The Metal Cutting Valve features the exclusive high-performance packing system with wire scraper rings that extends service life. Numerous features combine to provide a longer service life, less downtime and less maintenance than other valves currently used for these tough applications.

TRILLIUM Valves USA: Atwood & Morrill Forged Wye Globe Valves

Trillium Forged Wye Globe without backgroundTRILLIUM Valves USA announces the shipment of its first order of Atwood & Morrill Forged Wye Globe Valves. The valve shown is the first of nine forged F91 wye stop check valves for high pressure main steam lines to be installed at three combined cycle plants in the southeast United States.

Atwood & Morrill developed the forged ASTM A182 F91 valves to address life cycle concerns that have been identified by combined cycle power plants using cast ASTM A217 C12A valve bodies.

Forged valves minimize material defects and provide better quality and longer life valves.  

Mark Claffey, TRILLIUM Valves USA President, commented, “The Product Development Process for F91 gate and wye valves started in 2017. We introduced the forged parallel slide gate valves in 2018 and we completed our first production cycle of the forged wye valves in September 2020. By developing Atwood & Morrill forged gate and wye valves, TRILLIUM Valves USA responded to customer needs within the power industry. This is a significant achievement and I would like to thank all members of the Development Team for their hard work and dedication.”

Valtorc: Spring Return Fail Safe Automated Knife Gate Valves

Valtorc spring return knife gate valveValtorc's spring return cylinders are available in 316SS, carbon steel Epoxy ends and can work with knife gate valves up to 20". The spring return linear cylinders can be designed "Man Safe" captured springs. This means the unit can be easily dismantled and repaired on site without special equipment.

As standard the spring return cylinders are welded shut to prevent tampering and accidental removal of the end caps.

The captured spring design can be easily removed, is safe, heavier and more expensive. However, our welded end design is cheaper, lighter, more compact and able for non-field repair.

The spring options are available in spring to close or spring to open.

The back-up systems are bulky and rely on complicated accessories which can fail. The Valtorc spring return cylinders are more robust and more compact.
