Discover four main benefits of inflatable seal spherical valves for your equipment and production lines.

1. Bubble-Tight Sealing

Bubble-tight sealing means no leakage of material or passage of gas pressure. This is ideal for environments that are sensitive to air/oxygen ingress such as vacuum drying or reaction processing. 

The Roto-Flate also seals dynamically, which means it can maintain a bubble-tight seal against pressure or vacuum. This is ideal for processes that shift from pressure to vacuum during the same cycle. This is a requirement of many vacuum drying/vacuum reactor processes and one that presents a problem for typical discharge valves. The Roto-Flate is an ideal choice for such applications!

2. More Efficient Pneumatic Conveying

Many valves used in pneumatic conveying, such as knife-gate or slide-gate valves don’t provide tight seals, even when they are new from the factory. This means that vacuum pumps or air compressors have to work to overcome the constant leakage of air or process gasses. Because the Roto-Flate provides a bubble-tight seal, vacuum pumps and air compressors aren’t overloaded and so they work more efficiently. 

3. Unobstructed Flow of Product

Butterfly valves are frequently used in dry material handling processes and are favored for their low cost. Unfortunately, they have a vane directly in the middle of the product stream which significantly cuts throughput and often causes product bridging. The dome of the Roto-Flate valve rotates completely out of the way of the inlet opening, providing a fully-open bore that won’t obstruct product flow. This means that smaller Roto-Flate valves can be used to accomplish the same job which reduces the price differential. 

4. Minimized Wear

Seal wear is a constant worry in demanding valve applications. Most times, wear is a function of the process media abraiding the sealing surfaces as it flows past. But the sealing surfaces of the Roto-Flate are hidden from product flow when the valve is fully open. 

As such, even abrasive, materials will not wear the seal as with standard valve assemblies.

What Are the Pros and Cons of Using Air Piloted Valves?

Air piloted valves are a type of pneumatic valve that can be used in various applications. They are controlled by air pressure and regulate compressed air, liquid and gas.

It’s important to understand the benefits and potential disadvantages of air piloted valves to determine if they’re right for your job.

5 Benefits of Air Piloted Valves

#1: Easy Maintenance

Also known as air operated valves and air piloted pneumatic valves, these devices have fewer moving parts than their solenoid and manual counterparts. The simple, robust design requires less maintenance, allowing efficiency without constant upkeep. These valves have a high shifting force and tight seal, aren’t easily damaged and don’t require frequent replacement.

#2: Cost-Effective

Air operated valves are smaller and more efficient than solenoid and manually operated valves. They use less compressed air and the durable design demands fewer upgrades and repairs. They provide long-term cost savings, especially because they don’t need excess maintenance. Air piloted valves last several years when properly maintained, so you won’t have to purchase replacements frequently.

#3: Safety

These valves can handle volatile environments where electricity could result in combustion. They can be employed in operations that aren’t safe for manual valves and mounted in remote locations.

#4: Versatility in Applications

Air piloted valves can be easily integrated into automated systems. They’re available in 2-, 3- and 4-way normally opened or closed designs, making them suitable for on-off functions, pressure regulation and directional control. They function as slave and lockout valves to complete simultaneous and interlocking functions.

#5: Reliable in Harsh Conditions

Air operated valves are designed for hazardous, wet and dirty applications. For example, an air piloted valve would work well in an application where you must transition from contaminated to clean air.

You’ll find air piloted pneumatic valves in:

• Industrial applications
• Water treatment operations
• Chemical processing
• Food and beverage production
• Power generation
• Medical applications
• Oil and gas refining processes

Potential Issues with Air Piloted Valves

Noise Generation

Operation-induced vibrations may make valves noisy. You could also encounter aerodynamic noise generated by the release of compressed air or gas in certain applications. That might be problematic and disruptive when used for medical equipment.

Limited Precision in Some Applications

Air piloted valves aren’t suitable for all operations. They are commonly used as an on-off switch, so they aren’t the best valve for complex functions.
