Pneumatic roller lever valves, used for mechanical position sensing in machine automation systems. The linear horizontal movement of a machine part or passing material, for example on a conveyor line, moving over the roller operates the valve. The wheel rotates in the direction of the moving part which reduces friction, this minimises wear and tear of both the pneumatic roller lever valve and the travelling part, for this reason, a preferred method of mechanical sensing.
Pneumatic roller lever valves, constructed from a die-cast zinc aluminium alloy that is machined and lacquered offering strength and reliability, an overall excellent quality product. We offer 2 or 3-way normally closed, or a 5-way roller lever valve in either poppet or spool designs. Choose from a standard pneumatic roller lever valve or a compact design should space be limited. An air pilot assisted version can be ordered, used when less force is available to actuate the lever for lighter operation.
Order one-way or two-way roller levers with spring return, air pilot return or double rollers. A double roller lever is used on machine carriages to reverse the direction of travel. Port sizes are G1/8 as standard. ATEX certification is possible within this range; details are in the data sheets for each product.
