Working Principle

Copper globe valves operate on a linear motion principle to control fluid flow:

Valve Closure: Rotating the handwheel lowers the disk onto the seat, blocking fluid flow and providing shut-off.
Flow Regulation: Partially lifting the disk creates a variable restriction, allowing precise control of flow rate.
Pressure Drop: The Z-shaped flow path creates a pressure drop, making globe valves suitable for throttling applications.
Sealing Mechanism: The precision-machined disk and seat ensure tight sealing even at high pressures.

Application Areas

Residential Plumbing

Used in water supply systems, heating systems, and appliance connections for flow control.

Commercial Buildings

Suitable for HVAC systems, water distribution, and fire protection systems in offices and hotels.

Light Industrial

Ideal for process control in food processing, pharmaceuticals, and chemical industries.

Installation & Maintenance

Installation Guidelines

Install the valve with the flow direction matching the arrow on the body.
Ensure proper alignment and support to prevent stress on the valve body.
Use appropriate tools for tightening connections to avoid damage.
Test the valve after installation to ensure proper operation and check for leaks.

Maintenance Recommendations

Periodically inspect for leaks, corrosion, or damage to the valve body and components.
Lubricate the stem threads annually to ensure smooth operation.
Replace gaskets and seals if signs of wear or leakage are detected.
Clean the valve internally if flow becomes restricted due to debris accumulation.

Frequently Asked Questions (FAQ)

Q: What is the maximum pressure rating for copper globe valves?

A: Our copper globe valves are rated up to PN25 (25 bar), suitable for most residential, commercial, and light industrial applications.

Q: Can copper globe valves be used with hot water systems?

A: Yes, they are designed to handle temperatures up to 120°C, making them suitable for both hot and cold water systems.

Q: What is the difference between a globe valve and a gate valve?

A: Globe valves use a linear motion disk for throttling and precise flow control, while gate valves use a rising gate for full flow or shut-off with minimal pressure drop.
