Abstract
A locking mechanism is configured to secure a seat on a valve. The configurations may include a pin with a tapered end. The pin extends into the valve body to engage with an engagement feature, like a slot, on the seat. The slot may reside on the downstream side of the seat. This location can provide ready access to the pin, for example, through various feature found on the valve body, such as a boss. For steam conditioning valves, the locking mechanism may prove useful because it allows the seat to easily remove from the valve body.
