Ash Valve

The Valve is designed to address higher pressure applications up to 100 psig (6.8 barg) and higher temperatures up to 350#C. It is engineered for higly abrasive applications and requires minimal maintenance over the life of the valve. Featuring patented rising-blade technology ensures an optimal seal and a positive material shutoff with the use of lifting lugs. This prevent the blade from jamming or packing material upon closure, which can cause serious downtime. Unlike most knife gates, the Ash Valve contains replaceable seat that can significantly increase the life of the valve.

This fully bonneted slide gate consists of cast ductile iron flanges with a hardened 440C stainless steel blade and seat. Flanges match #120/150 ANSI or DIN mounting pattern with through holes and blind tapped holes. A double acting air cylinder actuates the valve open and closed and optional metering controls are available. Material contact is 440C stainless steel and ductile iron.


  • Rising blade and lifting lug design
  • Air Purge Port (to pressurize the bonnet and keep the material in the flow stream)
  • Replaceable Parts
  • High Temperature Design
  • Suitable for Highly Abrasive Material (minerals, frac sand, fly ash).
