Product details
A gate valve is a type of valve that is primarily used to start or stop the flow of fluid in a pipeline. It operates by lifting a rectangular or circular gate out of the flow path, allowing for unobstructed flow when fully open and complete closure when fully shut. Key Characteristics: • Design: Typically features a wedge-shaped gate that slides between two seats. The design allows for minimal resistance to flow when the valve is open. • Operation: Can be operated manually with a handwheel or automatically with an actuator. It is designed for on/off service rather than throttling. • Sealing: Provides a tight seal when closed, preventing leakage. Advantages: • Low Flow Resistance: When fully open, gate valves offer minimal turbulence and resistance, making them ideal for applications requiring unrestricted flow. • Durability: Built from materials like cast iron, stainless steel, or brass, ensuring long-term reliability and resistance to wear. • Versatile: Suitable for a wide range of applications, including water, oil, and gas systems. Applications: • Water Supply: Commonly used in municipal water systems for controlling flow to different sectors. • Oil and Gas: Essential in pipeline systems for shutting off flow during maintenance or emergencies. • Industrial Processes: Found in various manufacturing settings where isolation of fluid flow is required. In summary, gate valves are an effective choice for applications that require reliable on/off control with minimal flow resistance. Their robust design and versatility make them a staple in many industries.
