HD/MD Reject Chamber Valve Round by Round Flanged

Features and Benefits

1. The NPV HD/MD Reject Chamber knife gate valve is designed specifically to handle the wire, staples, glass, and sand typically found in recycle paper mill reject systems

2. Cavity-free, precision machined, special body casting prevents accumulation of solids and trash which would prohibit the valve from fully cycling

3. The gate, seat cartridge, and gate guide are 420SS heat-treated and hardened to an RC60, which extends the life cycle of the valve

4. Valve design allows for complete factory rebuild to like new condition at 50%-60% of the current list price

5. Gates are chrome-plated to reduce friction and valve torque extending the life of the packing

6. All NPV/DUCO valves are supplied with NPV high-cycle pneumatic cylinders, limit switch brackets, and stainless steel cylinder lockout

7. HD/MD Reject Chamber Round by Round Flanged Valve is available in sizes 6″, 8″, 1 O” & 12″
