Honeywell Pneumatic Fail-Safe Spring Return - MP953C1554/U

The Honeywell Pneumatic Fail-Safe Spring Return is an efficient control system equipped with a dual barbed fitting. This fitting is compatible with 5/32-inch outer diameter and 1/4-inch outer diameter plastic tubing, providing easy installation and robust connection. The controller operates on direct acting pressure of 2 psi to 7 psi and is characterized by a 3/4-inch stroke.

One of the primary features of this controller is its rolling diaphragm, which guarantees longevity and minimal hysteresis, contributing to reliable performance and durability. Versatility is another advantage as this component can be conveniently attached to a valve even post-piping, facilitating the installation process.

It features a slide lock for effortless engagement to the valve stem, offering either direct or reverse action control. However, it is worth noting that this product does not come with a positive positioner, which needs to be secured separately based on application requirements.

In terms of technical specifications, the operating conditions for the Pneumatic Fail-Safe Spring Return range from freezing to relatively high temperatures, making it suitable for a variety of industrial environments. Specifically, it functions optimally in temperatures ranging from 0 degrees Fahrenheit to 140 degrees Fahrenheit or -18 degrees Celsius to 60 degrees Celsius.
