Gate Valves
The Forbes Marshall range bi-directional gate valves are ideal for isolation services in oil and gas, petrochemical, fossil fuel and nuclear power, steel, chemical, fertiliser and mining industries. They also find applications in the solar sector. These valves offer excellent shut-off features for minimal pressure loss.
- Pneumatic or electric actuator for on-off applications
- Compliance to latest fugitive emission norms
- Hard-faced seating surface and deep stuffing box
- Split wedge, parallel slide, double disc for high-pressure lines available on request
- Spring energised closing in the parallel slide design
Frequently Asked Questions
A gate valve is a linear motion valve used to start or stop the flow of a fluid. It works by lifting or lowering a gate (disc) perpendicular to the flow path. When fully open, it allows minimal flow restriction, making it ideal for full-flow applications.
Gate valves are best suited for applications requiring on/off control of fluid flow with minimal restriction. They are ideal for systems where the valve remains fully open or closed for extended periods. Common applications include water distribution, wastewater treatment, oil and gas pipelines, chemical processing, and power plants. Gate valves are also used in industries handling high-pressure or high-temperature fluids, as well as in applications involving slurries, viscous fluids, or gases. Their ability to provide a tight seal and low flow resistance when fully open makes them suitable for large-diameter pipelines and isolation purposes.
Gate valves offer low flow resistance when fully open, are suitable for high-pressure applications, and can handle a wide range of fluids, including liquids, gases, and slurries. They also provide a tight shut-off when properly maintained.
Both gate and globe valves are linear motion valves. However, gate valves are designed for on/off flow control, whereas globe valves are better suited for precise throttling and flow regulation.
Gate valves can handle high-temperature fluids if made from suitable materials like stainless steel or alloy steels, and are rated for the temperature and pressure of the application.
