Magnetic Lockable Flow Control Globe Valve

A Magnetic Lockable Flow Control Globe Valve is an advanced, multifunctional device engineered for secure and precise fluid management. It combines the essential throttling and fine-regulation capabilities of a standard globe valve with a tamper-resistant security feature. Its primary function is to allow operators to accurately set and maintain a specific flow rate or pressure through the linear motion of its disc or plug. The integrated magnetic lock then secures the valve's adjustment mechanism, preventing unauthorized or accidental changes to the preset position. This ensures long-term system balance, energy efficiency, and operational integrity, making it ideal for critical applications in HVAC systems, district heating, and commercial building services where settings must be reliably maintained.

Product Feature and Application

The Magnetic Lockable Flow Control Globe Valve features a specialized magnetic locking mechanism that prevents unauthorized tampering, making it a premier choice for public buildings and multi-unit residences. It combines precise throttling and flow regulation with enhanced security; the valve can only be adjusted using a dedicated magnetic key. This is ideal for preventing water theft and ensuring consistent balancing in shared HVAC or plumbing networks.

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 gate and globe valves, it is recommended to install with the stem vertical and the operating handle on top.

Operating Instructions

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

Inspection and Maintenance

2.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.

3.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.

4.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.
