Air valve switches detect valve position or air pressure in pneumatic systems and send signals to control systems. They confirm actuation and support interlocks.

Switch Types

• Pneumatic pressure switches – confirm air signals
• Valve position switches – open/closed feedback
• Air-to-electric switches – convert pneumatic signals
• Compact designs – mount on valves and manifolds

Choosing a Switch

Select set point range, electrical rating and connection. Adjustable set points add flexibility.

Centro supplies air valve switches.

Pneumatic relief valves protect air systems from overpressure by venting excess pressure automatically. They safeguard components, tanks and personnel.

Relief Valve Types

• Adjustable relief valves – set pressure to suit
• ASME safety valves – code-compliant tank protection
• Inline relief valves – circuit protection
• Brass and stainless – suit environment

Choosing a Valve

Select set pressure and flow capacity to handle maximum supply. Never set relief above component ratings.

Centro supplies pneumatic relief valves.

Products Available

• Sintered bronze mufflers – compact exhaust silencing
• Plastic silencers – high noise reduction
• Speed control mufflers – adjust exhaust flow
• Inline flow controls – meter in or out
• Banjo flow controls – mount at cylinder ports

Choosing Products

Match thread and flow size, and use meter-out speed control for most cylinder applications.

In-line filters give point-of-use protection for valves, regulators, actuators and instruments in compressed air lines. Installed right where clean air matters most, they catch particles, moisture and oil that get past upstream filtration.

In-Line Filter Options

• Particulate filters – 5, 25 and 40 micron elements
• Coalescing in-line filters – remove oil aerosols
• Push-to-connect filters – install directly in tubing runs
• Disposable and serviceable designs – choose based on maintenance needs
• Clear bowls – check contamination at a glance

Choosing a Filter

Match the connection size and flow to the device you're protecting, and choose the micron rating based on its sensitivity. Proportional valves and instrument air usually need finer filtration. Replace elements when they look discolored or pressure drop rises.

Centro carries in-line filters for pneumatic and electronic control systems.
