O’Mara Pneumatic Slide Gates are engineered to start, stop, and meter the flow of grain, seed, feed, and other dry bulk materials with speed and precision. Powered by compressed air, these heavy-duty automated gates deliver quick response, tight shut-off, and dependable performance in high-volume agricultural and processing environments, from daily operation to peak harvest demand.
Each gate is designed with smooth internal transitions, UHMW wear strips, and rounded-head hardware to eliminate ledges, edges, and catch points where material can build up. This clean-flow design helps prevent seed hang-up and material carryover so that you can move from one batch or product type to the next without the need for cleanout or the risk of cross-contamination.
No matter whether you are controlling grain bin discharge, batching ingredients, protecting downstream equipment, or isolating a processing line, pneumatic slide gates from O’Mara provide smooth, one-touch material control exactly where your system needs it most.
A pneumatic slide gate is an air-powered mechanical valve used to regulate, isolate, or completely shut off the flow of free-flowing bulk materials such as corn, soybeans, wheat, seed, feed, fertilizer, or dry chemicals.
Instead of manual handwheels or electric motors, these gates use a compressed-air cylinder to move a steel slide blade across an opening. This straight-line motion allows the gate to:
Pneumatic slide gates are commonly installed at:
In simple terms, they provide fast, automated, and reliable control of grain movement throughout an entire facility.
The air-powered actuator delivers quick opening and closing speeds, allowing operators to control discharge rates accurately. This helps:
A tight-sealing slide blade stops material flow when closed—critical for:
Precise pneumatic positioning supports repeatable ingredient dosing in feed mills, seed plants, and grain processing systems, improving product quality and consistency.
Because the gate is air-actuated, operators can control it remotely or use PLC automation, reducing manual labor and limiting exposure to moving grain handling equipment.
Compressed air provides rapid actuation, ideal for feed mills, blending systems, and other operations requiring frequent cycling.
Controlled blade positioning supports repeatable volumetric flow, improving batching accuracy and reducing product giveaway.
Remote pneumatic control keeps personnel away from high-risk discharge points and moving machinery.
Tight seals and smooth slide action help prevent leakage, spills, airborne dust, and product mixing.
Rugged steel construction and abrasion-resistant components withstand constant grain impact, head pressure, and hard daily use.
O’Mara pneumatic slide gates are trusted across agricultural and industrial bulk material systems for:
Anywhere fast, automated material shut-off or metering is required, a pneumatic slide gate plays a critical role.
Every O’Mara pneumatic slide gate is built for dependable performance in demanding grain processing environments.
Each gate is matched to your material type, flow rate, pressure load, and operating environment for long-term reliability.
No two facilities operate the same way. O’Mara designs pneumatic slide gates to match your exact process and layout.
