"Failure Is Not an Option" - Kinetrol Manual and Fire Fail-Safe Spring Units

If you want to operate a valve manually, but maintain the advantage of the fail-safe spring's certainty of position when unattended, check out the Kinetrol's manual and fire fail-safe spring handle. This uniquely designed manual operator offers some compelling benefits in automating valves and provides additional plant safety levels. Spring return (also known as "deadman") handles will help you meet individual plant safety requirements and OSHA requirements for valves that must return to the closed position after an operation. Unlike lever handle or gear operators that will leave the valve in the last state, the spring return deadman device ensures that the valve returns to its original starting position powered by the associated spring handle.

If you want to operate a valve manually, but maintain the advantage of the fail-safe spring’s certainty of position when unattended, use this device.

These spring return units are designed to be put on valves to prevent, or limit, the impact of potentially hazardous accidents resulting from uncontrolled flowing fluid and gasses or spillage.

The Kinetrol manual fail-safe spring unit has a ISO/DIN female drive for direct mounting and ATEX category 2 options for use in hazardous areas. Kinetrol also offers a range of fire fail-safe spring assemblies that can be set to operate valves at pre-configured temperatures.

Because they cannot be left in the wrong position, they are commonly referred to as "deadman handles". Theses devices provide reliable torque delivery for valve reseating and come with completely sealed spring housings that meet IP65 levels, totally protecting the internal spring from the environment, making them ideal for outdoor applications.

Innovative Approach to Add Manual Failsafe Handles for Large Quarter-Turn Valves

Let's assume you have an application where it's critical that a large, pneumatically actuated valve cannot be left unattended in the wrong position (opened or closed). Or maybe your application requires the use of a manual operator with a fire-safe fusible link. The problem though, is the valve you want to control has torque requirements much greater than the output of any manual failsafe unit can provide. 

Here's an innovate and effective way to incorporate a manual failsafe unit on large size ball, butterfly, or plug valves. 

Retrofit your large valve with a 3-way "L" port ball valve and a manual failsafe spring handle on the large valve actuator's inlet air supply port. 

This allows the opening of the valve with the manual failsafe handle. When the handle is released, the valve shuts automatically by venting the air to atmosphere, and allowing the springs in the actuator to close the valve. 

Size limitations on the valves are no longer an issue, and this will work on anyone's pneumatic spring return actuator (spring return required, will not work on double acting actuators).
