Gate Valves

Gate valves are widely used in industrial and commercial applications for on/off flow control. These valves are designed to provide minimal resistance to fluid flow when fully open, ensuring high efficiency.

Gate Valves

Applications:

• Wastewater treatment plants
• Storage tanks
• Oil and gas pipelines
• HVAC systems
• Chemical processing

Key Features:

• Low-pressure drop
• Reliable sealing
• Suitable for high-temperature and high-pressure applications

Installation Guidelines

Step-by-Step Installation:

• Ensure that the pipeline is depressurised before installation.
• Verify the valve size and specifications to match the pipeline requirements.
• Align the valve with the pipe flanges and tighten the bolts evenly to avoid misalignment.
• Test for leaks after installation by gradually introducing pressure.

Maintenance Recommendations

• Periodically check for leaks or signs of wear.
• Lubricate moving parts to ensure smooth operation.
• Replace damaged or worn-out seals and seats promptly.
