Overview

The working principle of the cast steel extended stem electric flange gate valve Z941H-16C DN150 is similar to that of a regular electric gate valve. Both use an electric actuator to drive the valve stem, which in turn drives the gate to perform vertical lifting and lowering movements, achieving the opening and closing of the valve to control the flow of fluid in the pipeline.

Cast steel extended rod electric flange gate valve Z941H-16C DN150working principleThe working principle of the extended stem electric gate valve is similar to that of a regular electric gate valve. Both use an electric actuator to drive the valve stem, which in turn drives the gate plate to move vertically up and down, achieving the opening and closing of the valve to control the flow of fluid in the pipeline. The difference is that the electric actuator of the extended stem electric gate valve is connected to the valve stem through the extended stem, transmitting power to the valve body. Even if the valve is installed underground, at high altitude, or in other difficult to operate positions, it can be controlled from a distance.
structural characteristics：

sealing performanceBy using combination packing, corrugated pipe sealing and other methods, the leakage rate can be as low as ≤ 1 × 10 ⁻⁶ m ³/s, which meets the ISO 15848-1 Class A standard. The dynamic sealing life of the rod body is ≥ 10000 opening and closing cycles under normal working conditions.
structural strengthExtended rods are usually made of solid round rods, such as 2205 duplex steel, with a tensile strength of ≥ 620MPa and a yield strength of ≥ 450MPa. When the rod length exceeds 3 meters, add a middle bracket to control the deflection to ≤ L/1000, ensuring that the rod body is coaxial with the valve stem.
Protection levelThe protection level of ground actuators can reach IP66, and for underground or underwater scenarios, it can reach IP68, effectively preventing rainwater, dust, seawater, and other intrusion.

main advantages：

Operational SecurityThe electric actuator can be extended to a safe area to prevent operators from working in hazardous environments such as underground wells, high temperatures, and flammable and explosive conditions.
Adapt to harsh working conditionsCan isolate the actuator from harsh environments, reduce the impact of high temperature, high humidity, corrosion, etc. on the actuator, and extend the service life of the equipment.
Convenient maintenanceNo need to frequently excavate the road surface or build scaffolding, maintenance can be carried out directly at the operating end, reducing maintenance costs and difficulty.
Adapt to intelligent upgradeSensors such as temperature, torque, and displacement can be embedded inside the extension rod to achieve remote monitoring and predictive maintenance.

Cast steel extended rod electric flange gate valve Z941H-16C DN150Application scenarios：

Underground pipelines and deep buried systemsFor municipal underground pipelines, underground comprehensive pipe galleries, etc., handwheels or electric actuators can be extended to the ground or maintenance platform for easy operation and maintenance.
High temperature, high pressure, and hazardous working environmentIn industrial kilns, reaction vessels, and petrochemical storage tank areas, the control end can be set in a safe area to meet explosion-proof requirements.
Energy and Power EngineeringSuitable for power plant boilers, steam turbine systems, wind power, photovoltaic energy storage systems, etc., ensuring reliable operation in high temperature, high pressure and other environments.
Ocean and Underwater EngineeringThe seawater intake valve of a seawater desalination plant can be connected to the shore control cabinet through an extension rod to achieve remote automation control.
