Abstract
The valve seat of the present invention is configured for attachment to the valve housing after the valve housing has been coated with a protective coating. The valve seat is configured to grip the valve housing, thereby providing a secure attachment. In its simplest form, the valve seat and the valve housing are both configured with corresponding locking-ring grooves, and a locking-ring element is positioned so as to be at least partially deployed in both the valve seat locking-ring groove and the valve housing locking-ring groove simultaneously. It will be appreciated that the features of the present invention may be used to benefit with substantially any type and style of valve known in the art.
