Abstract
A gate valve having a seat plate with a recessed face smaller in width than a bore of the valve. The recessed face includes an opening, which can be generally rectangular for use of the valve as a substantially linear control valve. The valve closes by movement of the gate along the recessed face to obstruct the opening, and opens by the reverse movement.
