Frequently Asked Questions

What is the main benefit of the HART communication in this model?

HART allows two-way digital communication. You can configure, calibrate, and diagnose the V18345-1020521001 remotely using standard tools, saving time.

What does 'double-acting, fail-freeze' mean for operation?

It controls actuators with two air ports. During a power failure, it locks both air outputs. This holds the valve securely in its last position.

Does this model provide a valve position signal?

Yes. It includes an analog feedback module. This gives a separate 4-20 mA signal that matches the valve's 0-100% position.

Can I adjust the control response sensitivity?

Yes. The adjustable dead band from 0.1% to 10% lets you prevent small actuator movements from signal noise.

Is this device suitable for high-vibration environments?

Absolutely. It is tested to perform within ±1% accuracy under strong vibrations, making it ideal for pumps and compressors.
