Fabri-Valve 33 PTD Light to Medium Duty Slurry Valve
The Fabri-Valve 33 PTD is a light-to-medium duty push-through slurry valve that seals by axially compressing matched elastomer sleeves. Packingless and self-flushing, with UHMWPE liners guiding the gate through its full stroke, it brings the sleeve-sealed slurry valve concept to everyday abrasive and corrosive services at an accessible duty level.
Product Benefits
- No metal in the flow: When the valve is open, only the elastomer sleeves face the process, so the housing and gate stay out of contact with the media.
- Self-flushing action: Every stroke clears solids from the sealing area as part of normal operation.
- Bubble-tight both ways: The valve shuts off bi-directionally, and every unit is factory tested to confirm it.
- UHMWPE gate liners: A pair of gate support liners guides the gate through the entire stroke, reducing wear on both sleeves and gate and extending service intervals.
- Nothing to adjust: There is no packing to set and no lubrication to schedule.
Where It's Used
- Light and medium duty slurries: The 33 PTD is matched to abrasive and corrosive services that do not demand the heaviest valve class.
- Process and transfer lines: Typical placements are process branches, transfer lines, and utility slurry services.
- Full-ported flow: The full-ported opening passes solids freely and keeps pressure loss low.
- Wide actuation choice: Handwheel, bevel gear, air cylinder, hydraulic cylinder, and electric operators are all available.
- Lockout ready: Built-in open and closed lockout/tagout positions support safe isolation procedures.
Good to Know
- Steel body, stainless gate: The housing is mild steel with a stainless steel gate.
- Sleeve materials: Natural rubber sleeves are standard, with EPDM available for hotter or more chemically demanding services.
- In-line sleeve changes: Heavy-duty sleeves are replaceable without disassembling the valve, so a sleeve change is a quick in-line job.
- Plan for drainage: As with any push-through design, a small discharge occurs at mid-stroke as part of the self-flushing action, so provide for drainage at the valve.
- Choosing the duty class: The choice between the PTD and its heavy-duty counterpart mainly comes down to the severity and pressure of the service. Fluindo can help place your application on that spectrum.
