Carbon Steel WCB High Pressure Welded Gate Valve DN100 PN150

Introduction to Gate Valve

Product Features: Made of stainless steel (corrosion-resistant, suitable for clean and corrosive working conditions), welded connections (suitable for high-pressure pipelines, providing a reliable seal), a handwheel-driven valve stem controls the gate opening and closing, and a multi-bolt bonnet secures the valve cap (ensuring a high-pressure seal). This rising-stem gate valve (the valve stem rises and falls with the valve, providing a visual status display) is suitable for high-pressure, high-demand applications such as those in the petroleum, chemical, and power industries (such as high-temperature steam and high-pressure fluid control). It precisely controls the flow of media and ensures safe system operation, making it a representative high-end industrial valve.

Structure and Function: Welded connections (suitable for high-pressure pipelines, providing a more reliable seal), opens by the thrust of the media flow, and automatically closes in the reverse direction (by the valve disc's own weight or spring assistance), with a multi-bolt bonnet secures the valve cap (ensuring a high-pressure seal). Commonly used in high-pressure systems in the petroleum, chemical, and power industries (such as compressor outlets and high-pressure fluid transportation), it prevents backflow and damage to equipment, ensuring safe and stable system operation. It is a key component for backflow prevention in high-pressure pipelines.

Application scenarios: Due to its corrosion resistance and reliable sealing, it is suitable for chemical and pharmaceutical (acid and alkali media), food and beverage (hygienic requirements), marine engineering (salt spray corrosion) and other scenarios. It accurately controls the flow of media to ensure safe and clean operation of the system. It is a key control component for high-end industrial pipelines.
