Article How It Works: Gate Valves
Stop, allow, or throttle the flow of process fluid with very low friction loss.
The FLS-DA2 gate valve is designed for positive control of high-pressure frac valves and for many subsea and drilling applications. This design is a combination of our field-proven FLS gate valve with a double-acting hydraulic actuator.
The FLS-DA2 gate valve is fitted with a balancing lower stem to work in conjunction with a double-acting hydraulic actuator to provide positive, reliable control throughout the entire stroke of the valve. Should a failure of hydraulic power occur, this valve will remain in position.
