A Gate Valve is a linear motion valve designed to completely start or stop the flow of fluid in a pipeline. The gate moves vertically by means of the valve stem, opening or closing the flow passage. When fully open, it provides a straight-through flow path with minimal pressure loss.
Gate Valves are widely used in water distribution systems, potable water networks, fire protection systems, HVAC installations, power plants, infrastructure projects and industrial process pipelines. Their durable construction, reliable sealing and long service life make them one of the most commonly used valve types.
Advantages
Minimal pressure loss when fully open
Excellent sealing performance
Suitable for large-diameter pipelines
Durable and long service life
Low maintenance requirements
Suitable for bi-directional flow
Safe and easy operation
Applications
Potable water systems
Water distribution networks
Fire protection systems
HVAC systems
Heating and cooling systems
Wastewater and infrastructure projects
Industrial plants
Power stations
Oil and petrochemical industries
Working Principle
When the handwheel or actuator is operated, the valve stem moves the gate upward to allow full flow. Rotating in the opposite direction lowers the gate, completely stopping the flow. Gate valves are designed for fully open or fully closed operation rather than flow regulation.
