FLS HYDRAULIC GATE VALVES

FLS HYDRAULIC GATE VALVES Supplier in China – Reliable Performance and Advanced Technology

FLS hydraulic gate valves are engineered for reliable, high-performance applications in a range of industries. These valves are equipped with a double-acting hydraulic actuator, requiring an operating pressure between 1500 and 3000 psi. The actuator is designed to provide efficient valve operation, where pressurizing the upper port (farthest from the valve) closes the valve, while pressurizing the lower port (closest to the valve) opens it.

One of the key features of the FLS hydraulic gate valve is its balanced stem design. This innovative design balances the pressure thrust on the upper stem, ensuring that the valve stays in position even after actuator pressure is released. The actuator does not contain springs, which improves its durability and reliability. The upper and lower stem packings effectively seal the line pressure, and if any minor leakage occurs past the upper stem packing, a vent port and seals above the vent prevent line pressure from entering the actuator.

The typical operating pressure of the FLS hydraulic gate valve is usually lower than the published minimum of 1500 psi, as this value accounts for potential fouling from drilling fluids and similar substances. In normal operating conditions, the actuator functions efficiently at lower pressures, and the valve is rated for a maximum working pressure of 3000 psi.

For optimal performance, FLS hydraulic gate valves can operate with hydraulic oils or water containing water-soluble lubricants such as 590X, which protects the hydraulic system and ensures smooth flow. When using water-based fluids, it's essential to add the appropriate amount of ethylene glycol for freeze protection.

The position of the valve can be easily monitored by observing the lower stem, which moves in conjunction with valve operation. The valve position is indicated through slots in the lower stem protector/indicator. When the valve is open, the lower stem is raised (toward the valve body), and when the valve is closed, the lower stem is lowered (away from the valve body).
