Product Description:

API 6A FC Type Hydraulic Gate Valve

1.Designed, manufactured and tested in Accordance with API Spec. 6A.

2.Linear double acting actuators guarantee opening valves rapidly in 30 seconds 

3.Integrally forged valve body,The sealing surface of the gate are sprayed by carbide alloy at high velocity and seats are made of carbide alloy to enhance wear resistance, corrosion resistance and service life

4.Gate to seat, seat to body, bonnet seal and stem backseat are metal to metal sealing

5.The gate valve is fitted with a balancing lower stem to work with a double acting hydraulic actuator to provide positive, reliable control through the entire stroke of the valve. Should a failure of hydraulic power occur, this valve will remain in position.

6.Double acting actuator that requires hydraulic power to both open and close, providing positive control during operations

7.Balancing stem that allows gate to stay in position unless hydraulic power is supplied to actuator to positively open or close valve

8.Two spring-loaded, pressure-energized, nonelastomeric lip seals between each seat and body, which assist in low-pressure sealing and protect against intrusion of particle contaminants into the body cavity and seal areas

9.Stem seal design that covers a wide range of pressures, temperatures, and fluids encountered in wellhead and manifold service Metal-to-metal bonnet seal

10.Manual locking screw that maintains the gate (valve) in the closed position without any operating pressure in the actuator

11.Use of socket head cap scre ws to tie down actuator head flanges, reducing area exposed to corrosive environments

Technical parameters:

The Hydraulic FC Gate Valve is a critical flow control component widely used in high-pressure oilfield applications, including wellhead systems, fracturing operations, and manifold control systems. Designed and manufactured in strict accordance with API 6A specifications, this valve ensures reliable performance under demanding operating conditions.

This Hydraulic FC Gate Valve is equipped with a linear double-acting hydraulic actuator, enabling rapid and stable valve operation. The actuator system ensures that the valve can be fully opened or closed within approximately 30 seconds, providing efficient response in dynamic pressure environments. The double-acting design requires hydraulic power for both opening and closing, delivering precise and positive control throughout the entire stroke.

The valve body is integrally forged to enhance structural strength and pressure-bearing capacity. Critical sealing components, including the gate and seats, are treated with high-velocity carbide alloy spraying technology, significantly improving resistance to wear, erosion, and corrosion. This design extends the overall service life of the Hydraulic FC Gate Valve, even in abrasive and high-temperature conditions.

To ensure superior sealing performance, the valve adopts a full metal-to-metal sealing structure, including gate-to-seat, seat-to-body, bonnet seal, and stem backseat sealing. This configuration provides high integrity sealing under both high and low-pressure conditions, reducing the risk of leakage and improving operational safety.

The balancing lower stem design allows the valve to maintain its position in the event of hydraulic power failure, ensuring operational stability and safety. Additionally, the stem seal system is engineered to accommodate a wide range of pressures, temperatures, and fluid types commonly encountered in oilfield operations.

For enhanced sealing at low pressure and protection against contamination, the valve incorporates two spring-loaded, pressure-energized non-elastomeric lip seals between each seat and body. These seals effectively prevent particle intrusion into the body cavity and sealing areas, maintaining long-term sealing reliability.

The Hydraulic FC Gate Valve is also equipped with a manual locking screw mechanism, allowing the valve to remain securely in the closed position without requiring continuous hydraulic pressure. This feature is particularly valuable in maintenance or emergency scenarios.

To improve durability in corrosive environments, socket head cap screws are used to secure the actuator head flanges, minimizing exposed surface areas and reducing the risk of corrosion-related damage.

Overall, this Hydraulic FC Gate Valve provides a robust, high-performance solution for critical flow control in oil and gas operations, combining fast actuation, reliable sealing, and long service life to meet the stringent demands of modern energy infrastructure.
