Infinity Pneumatic Axial Valve

Infinity Pneumatic Axial Valve (Series 90740)

The Compact Powerhouse for Automated Air Control

Modernize your facility and stop manual valve operation with the Infinity Pneumatic Axial Valve (Part 90740). This advanced valve is designed to act as an automated “gatekeeper” for your compressed air system, allowing you to open or close air lines remotely via a pneumatic signal.

Unlike bulky automated ball valves that require large external actuators and brackets, the Axial Valve features a sleek, inline design that is barely wider than the pipe itself. It integrates seamlessly into your Infinity aluminum piping system using standard push-to-connect technology, making it the perfect solution for zoning, safety isolation, and energy management.

The “Energy Saver” Valve

The most common application for the 90740 is Energy Conservation. By linking this valve to a timer, light switch, or PLC, you can automatically shut off air supply to specific production zones or machines when they are not in use (e.g., at night or during shift changes). This prevents expensive compressed air from leaking out of idle tools during off-hours.

Key Features & Benefits

• Integrated Push-to-Connect Ends: Installation is instant. There are no threads to seal or adapters to buy. The valve body features the standard Infinity stainless steel grab-ring system—simply cut your aluminum pipe and push it into the valve ends.
• Full-Bore “Axial” Flow: The internal piston moves axially (straight back and forth) rather than rotating. This allows for a straight-through flow path with minimal turbulence and almost zero pressure drop, ensuring your downstream tools get full power.
• Compact Inline Footprint: Designed to fit into tight spaces, cable trays, or along walls where a standard automated ball valve with a protruding actuator would not fit.
• Rapid Response Time: Switching is nearly instantaneous. The pneumatic pilot allows for fast cycling, making it suitable for process control applications.
• Remote Pilot Operation: Controlled by a simple 1/4″ or 6mm air line (pilot signal). This keeps high-voltage electricity away from the pipe itself—the electrical solenoid can be located safely in a control panel away from the valve.

Technical Specifications

• Part Number: 90740 Series
• Valve Type: Pneumatic Axial (Coaxial) Valve
• Actuation: Pneumatic Pilot Operated (Requires a pilot signal to switch)
• Configuration: Typically Normally Closed (NC) or Double Acting (Check specific size model)
• Working Pressure: Up to 232 PSI (16 Bar)
• Pilot Pressure: Typically 60–120 PSI required to actuate
• Material: Nickel-Plated Brass / Anodized Aluminum
• Available Sizes: Fits standard Infinity Pipe sizes (32-63mm)

Ideal Applications

• Zoned Isolation: Automatically cutting off air to the “Assembly Department” when the lights are turned off.
• Machine Safety: Interlocking the air supply with machine guards (if the door opens, the air cuts off).
• Hazardous Areas: Safe for use in wet or dusty environments because there are no electric motors on the valve itself.

How It Works

1. Install: Push the Infinity pipe into the inlet and outlet.
2. Connect Pilot: Run a small 6mm air tube from a solenoid valve (control switch) to the pilot port on the Axial Valve.
3. Operate: When you send air down the pilot tube, the internal piston slides back, opening the main valve. When pilot pressure is removed, a spring forces the valve closed (on NC models).
