10Inch 150LB WCB DBB Plug Valve Manufacturer | ZZJG VALVE

31 Aug, 2026

ZZJG VALVE recently completed the production and inspection of a batch of 10-inch 150LB WCB Double Block and Bleed Plug Valves. These DBB Plug Valve use WCB carbon steel valve bodies, with a pressure rating of Class 150 and a maximum diameter of 10 inches. These valves are used in petroleum, natural gas, chemical, power, and general industrial piping systems.
 

 
1. 10-inch Large Diameter Design, Suitable for Large Pipe Systems

This 10-inch Dual Expanding Double Block and Bleed Plug Valve is used in large industrial pipelines. The DBB Plug Valve adopts a straight-through flow path, allowing the medium to pass through the valve smoothly. When fully opened, the medium can directly pass through the dbb plug valve body, and the internal flow path can reduce flow resistance and pressure loss. Large transportation pipelines require better flow performance, and good flow performance can keep the pipeline system running normally. Double Block & Bleed (DBB) Expanding Twin Seal Plug Valve also require good sealing performance and convenient operation methods. These features allow the Dual Expanding DBB Plug Valve to work stably in large pipe systems.

 

 2. WCB Carbon Steel Has Good Strength and Low Cost

This 10-inch Class 150 General Plug Valve has the main pressure-bearing components made of WCB carbon steel. WCB carbon steel has good strength and can withstand high pressure, is easy to cast and process. Many industrial valves use WCB carbon steel for valve bodies. WCB carbon steel can be used for petroleum, natural gas, water, and other common industrial media. The cost of WCB carbon steel is usually lower than stainless steel, and using WCB carbon steel can reduce project costs. For projects requiring good strength, reliable performance, and reasonable costs, WCB carbon steel is a common choice. 

 

 3. DBB Plug Valve for Pipeline Isolation

The API DBB Plug Valve controls the flow of the medium by rotating the valve plug. When the valve plug is in the open position, the valve plug flow path is connected to the pipeline, and the medium can pass through the valve. When the valve plug is in the closed position, the valve plug will prevent the medium from flowing, and the valve can isolate the pipeline. The structure of the Double Block & Bleed Valves is simple and the operation is convenient. This design is suitable for industrial systems that need to frequently isolate pipelines. For large-diameter valves, ZZJG VALVE can provide handwheels, gearboxes, or other actuators, and ZZJG VALVE will choose the appropriate operation method based on the project requirements. These operation methods can reduce the force required to operate the valve and make it easier for on-site personnel to operate the plug valve.

 

 4. Class 150 Pressure Rating, Suitable for Common Industrial Applications

General Plug Valve Twin Seal uses the ASME Class 150 pressure rating. Class 150 is one of the commonly used pressure ratings in industrial piping systems. The actual working pressure of the valve is affected by working temperature, valve material, and design standards. Each project needs to confirm the actual working pressure. When selecting a project, it is necessary to consider the medium type, working temperature, and working pressure, which can help customers choose the appropriate valve.

 

 5. Suitable for Petroleum, Natural Gas, and Chemical Piping

This 10-inch Class 150 WCB DBB Expanding Plug Valve can be used in various industrial piping systems, including petroleum transportation pipelines, natural gas pipelines, chemical process pipelines, power plant auxiliary pipelines, industrial water systems, tank inlet and outlet pipelines, and general industrial fluid pipelines. This double block and bleed plug valve is suitable for projects that require large-diameter pipeline isolation and can also help projects control valve procurement costs.

 

 6. ZZJG VALVE Provide Project Customization Services

Different industrial projects have different valve requirements. ZZJG VALVE will select the appropriate valves according to customer requirements. Customers can provide information such as pipe size, pressure rating, medium, temperature, connection standard and operation mode. For this 10-inch Class 150 WCB double-sealed relief plug valve, ZZJG VALVE use a reliable WCB carbon steel design and complete valve manufacturing and assembly before shipment. ZZJG VALVE also conduct quality and performance checks on the valves. ZZJG VALVE offer large-diameter plug valves and other industrial valves, which can be used in oil, gas, chemical, power and other industrial pipeline systems.
