Working Principle

Copper gate valves operate on a simple yet effective principle to control the flow of fluids in plumbing systems:

Flow Control: The valve consists of a gate (or wedge) that moves up and down perpendicular to the flow direction. When the gate is fully raised, the valve is open, allowing maximum flow. When the gate is fully lowered, the valve is closed, stopping all flow.
Operation: Turning the handwheel rotates the stem, which moves the gate up or down. The rising stem design shows the valve's position visually - when the stem is extended, the valve is open; when retracted, it's closed.
Sealing: When closed, the gate presses against the valve seats, creating a tight seal that prevents leakage. The seats are typically made of soft materials like PTFE or rubber for excellent sealing performance.
Pressure Management: The full-port design minimizes pressure drop when the valve is open, allowing for efficient system operation. The robust copper construction ensures the valve can withstand the pressure and temperature requirements of various applications.

Institutional Facilities

Used in hospitals, schools, universities, and government buildings for reliable water flow control in various systems and applications.

Light Industrial

Suitable for light industrial applications such as food processing, pharmaceuticals, and electronics manufacturing where clean water and reliable flow control are essential.

Hospitality Industry

Ideal for hotels, resorts, and restaurants for water supply systems, including guest rooms, kitchens, laundry facilities, and swimming pools.

Plumbing Renovations

Perfect for renovation projects where existing plumbing systems need to be upgraded or modified with reliable, high-quality components.

Installation & Maintenance

Installation Guidelines

Ensure the valve is compatible with the system's pressure and temperature requirements.
Install the valve in the correct orientation, with the flow direction matching the arrow on the valve body.
For threaded valves, use Teflon tape or pipe dope on the male threads to ensure a leak-free connection.
For solder valves, follow proper soldering techniques, ensuring the valve is open during soldering to prevent damage to internal components.
Tighten all connections securely but do not over-tighten, which could damage the valve or pipes.
Test the valve after installation to ensure proper operation and check for leaks.

Maintenance Recommendations

Operate the valve regularly (at least once per year) to prevent seizing and ensure smooth operation.
Inspect the valve periodically for signs of leakage, corrosion, or damage.
Clean the valve exterior regularly to remove dirt and debris that could affect operation.
Lubricate the stem threads if the valve becomes difficult to operate.
Replace the valve if it shows signs of significant wear, corrosion, or damage that cannot be repaired.
Keep records of maintenance activities for future reference.

Frequently Asked Questions (FAQ)

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

A: Our copper gate valves are available with pressure ratings up to PN25 (25 bar), making them suitable for most residential, commercial, and light industrial applications.

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

A: Yes, our copper gate valves 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 threaded and solder connections?

A: Threaded connections use screw threads for installation, while solder connections require heating and melting solder to create a permanent bond. Threaded valves are easier to install and remove, while solder valves provide a more permanent, leak-proof connection.

Q: How long do copper gate valves typically last?

A: With proper installation and maintenance, copper gate valves can last 20-50 years or more, depending on the operating conditions and water quality.

Q: Are copper gate valves suitable for potable water systems?

A: Yes, our copper gate valves are certified to meet NSF/ANSI 61 standards for use in potable water systems, ensuring they are safe for drinking water applications.
