Humphrey TAC Miniature Push Button Valve Operators

Humphrey TAC Miniature Push Button Valve Operators complete the modular character of the TAC system. With these separate heads, you easily turn a standard manual push button valve into an air-piloted or mechanically activated valve. This creates huge flexibility in your machine design without needing a specific valve for every function. Inacom supplies these essential building blocks for every type of pneumatic circuit.

Tactical expansion: the 34A Air Pilot Operator

The most popular operator in this series is the 34A Air Pilot. When you screw this operator onto the collar of a TAC push button, the valve becomes a pneumatic relay.

• Low pilot pressure: The 34A needs only a fraction of the system pressure to activate the valve. The operator also responds immediately to the smallest pneumatic signal.
• Compact logic: Using air pilots, you build complex logic circuits in a very small footprint.
• Secure mounting: You screw the operator directly onto the thread of the valve body. You then lock it for a vibration-free connection.

Mechanical and manual heads

In addition to pneumatic actuation, the series offers various mechanical options for using the Humphrey TAC Valve Operators:

• Cam followers: Ideal for activation by a passing cam or machine part. That is why you often see them used as limit switches.
• Ball plungers: Suitable for linear activation where space is limited.
• Coloured push buttons: For better ergonomics and recognisability on control panels, you can easily fit larger mushroom buttons on the standard TAC valves.

Why choose modular operators?

The big advantage of working with separate operators is ease of maintenance. If a mechanical head wears after years of intensive use, you only replace the operator and not the entire valve. In addition, with the 34A series you can control a standard valve "remotely", which is essential in ATEX zones where you do not want to use electrical signals.

Inacom is happy to help you select the right combination of base valve and operator. This way you are always assured of a technically sound solution that fits your budget and available space.
