The UCC Environmental 40DH Knifegate Valve is designed specifically for on/off pipeline isolation service in pneumatic conveying applications of ash exposed to dry scrubbers and dry sorbent injection systems. The 40DH utilizes UCC’s proven 40D knife gate technology with a heated blade to help prevent material buildup. This helps improve the life of the packing, blade, and body in these extreme applications
- The heated blade prevents material build-up which improves packing seal performance and life.
- UCC’s spring-loaded packing gland design maintains seal pressure during operating and prevents leaks, minimizing maintenance and extending the life of the blade and packing.
- The 40DH has three different configurations utilizing a replaceable dual seat, flow cone, or wear liner to increase the valve wear life and allow for economical rebuilds.
