DUCO Scavenger design removes cavities/pockets thus eliminating problems caused from accumulation of solids that can prevent proper cycling of valve
Hardened gate, hardened seat cartridge, and hardened back up guide prolong life of valves in heavy solid and heavy trash applications
Hardened serrated ring and hardened beveled gate allow valve to shear heavy solids and still achieve effective metal to metal sealing
Hardened seat ring and hardened gate guide also serve as scrapers to prevent solids from being dragged into packing area when valve is cycled
Two-piece body design and use of replaceable wear components allow valves to be fully repaired by factory to like new condition, making DUCO valves very cost effective. Repair cost is 50-60% of the current list price of the valve.
All DUCO Scavenger valves are supplied with NPV high cycle pneumatic cylinder, limit switch brackets, and stainless steel cylinder lockout
Gates are chrome plated to reduce friction on packing, reducing valve torque and extending packing life
