ROLLING SLIDE GATE
Cleveland Armstrong®'s simplest and most widely used slide gate is the Rolling Slide Gate
(RS). Features for this unit include:
- Heavy-duty structural channel design
- Optional displacement pocket for cutting through a standing column of material
- Majority of product contact surfaces made of abrasion-resistant steel
- Unique seal arrangement that optimizes both sealing and cleaning of the blade
- Heavy duty regreaseable rollers

Dual Bladed Rolling Slide Gate
Our Rolling Slide Gate has a number of benefits. These are:
- Gate blade and seal retainers are constructed of 240 BHN for longer wear.
- Regreaseable cam follower rollers are needle bearings with nylon seals. These heavy-duty rollers
help guide and support the blade.
- Displacement pockets can be added to valves cutting standing columns of material. This allows
material to fall into the flow stream rather than being compressed against the frame.
- On larger blades, we chamfer the leading edge to assist its cutting through the material.
- Heavy-duty channel frame construction with structural angles to avoid gate frame deformation
under material loads.
- Seals along the four sides of the blade including a wiping seal to assure better sealing of
the gate.
Applications include, but are not limited to, shutoff, flow control and maintenance gates on: bins, hoppers,
screw conveyors, belt conveyors and vibrating conveyors.
On some high temperature applications or for use with very fine abrasive materials, PEBCO®
can supply a Slide Gate (SG) with cast iron slide bars in place of regreaseable rollers.
Depending on gate size and the need for rapid closure, PEBCO® offers a Dual Bladed
Rolling Slide Gate (DBRS).
ROLLING SLIDE GATE WITH PACKING
PEBCO®'s Rolling Slide Gate with Packing (RSP), or cast iron slide bar version with packing
(SGP), is suited to situations where it is crucial to avoid internal to external material leakage through
the blade seal arrangement. Advantages of the RSP/SGP are:
- Adjustable packing wraps around the blade to assure no internal to external leakage
- Low head room requirement
- Ability to seal under pressure or vacuum
PEBCO®'s Rolling Slide Gate with Packing offers the following advantages:
- Same design features of our standard Rolling Slide Gate.
- Instead of using our standard seal arrangement we incorporate a packing arrangement. This isolates
the front portion of the gate from the rear section.
- Proven design on finished cement and fly ash.
- Low headroom requirements.
