Abstract
A composite fracturing tree includes an operating valve and a master valve in fluid communication with the operating valve. The master valve includes an inlet portion in fluid communication with the operating valve, an outlet portion, and a gate portion. The gate portion is disposed between the inlet portion and the outlet portion. The gate portion is moveable between a flow position and an occluding position. In the flow position, the gate portion permits flow between the inlet portion and the outlet portion. In the occluding position, the gate portion prevents flow from the inlet portion to the outlet portion. The gate portion is actuated from the flow position to the occluding position with a closing force and from the occluding position to the flow position with an opening force. The master valve allows for the closing force to reduced compared to conventional fracturing valves.
