Motorized Globe Valve

Motorized Globe Valves are widely used in fluid and gas control systems to precisely regulate flow through automated electric actuation, providing accurate throttling performance, stable operation, and reliable shut-off capability. The globe valve structure allows fine flow adjustment, making it ideal for applications that require precise control in industrial, commercial, and energy systems.

Product Feature and Application

Motorized Globe Valves feature a high-torque electric actuator that drives a plug vertically to provide precise linear throttling. Unlike ball valves, their design allows for fine-tuned flow regulation and modulation. They are essential for HVAC air handling units, steam heating systems, and large-scale chillers where maintaining specific temperatures is critical. Their robust construction ensures stable performance under high pressure.

Installation Guidelines

1.Clean and prepare the piping system thoroughly before installing the valve.

2.Before installation, remove any protective end caps and inspect the valve ports and seating surfaces to ensure they are clean.

3.Provide adequate support for the valve to avoid stress from connecting piping.

4.Confirm that the valve’s pressure and temperature ratings are suitable for the intended service conditions.

5.Before placing the valve into service, cycle it fully from open to closed to verify smooth operation.

6.After installation, check that the packing nut is properly tightened.

7.For Motorized Globe Valves, it is recommended to install with the stem vertical and the operating handle on top.

Operating Instructions

Gate and globe valves are manually operated. Turn the handle counterclockwise to open and clockwise to close.

Inspection and Maintenance

1.Routine inspection and preventive maintenance are generally not required, aside from occasional adjustment of stem packing and periodic cycling of the valve from open to closed.

2.If a packing leak occurs, tighten the packing nut clockwise by about a quarter-turn—or until leakage stops—to increase sealing pressure on the stem packing. Never repack a valve while it is under system pressure.

3.When replacing the valve stem, also replace the packing material.

Replacement Parts

Under normal operating conditions, replacement parts are seldom needed. Recommended spare parts for each valve type include:

Globe valves: Handle, handle nut, packing, gland, packing nut, disc and seat.

When ordering parts, please provide the valve’s figure number, size, required part, and approximate age.
