5 Double-Block and Bleed Plug Valve Manufacturers (2024)

#1: PANS Valve

Location: Dongou Industrial Zone, Oubei, Wenzhou, 325102, China

PANS Valve is a leading name among double-block and bleed plug valve manufacturers.

Their rail-type cock design allows a secure and efficient valve operation, which features an advanced mechanism.

The DBB plug’s opening begins by raising the cock to a specific height, which will cause the sealing element to move away from the sealing surface.

Thus, ensuring a smooth 90-degree rotation to open.

When you close the valve, the cock and slider will now rotate.

This mechanism compresses the elastic sealing ring onto the valve body.

Moreover, PANS Valve products are widely used in sectors dealing with hazardous media, such as the following:

• Aviation kerosene
• Natural gas
• Liquefied petroleum gas

With their robust seal structures and corrosion-resistant properties, PANS Valves are suitable for industries that need high-performance and long-lasting solutions.

#2: Global Steel And Engineering

Location: Office No. 9, 1st Floor, 182/184 Saifee House, 6th Kumbharwada Ln, near Alankar Cinema, Mumbai, Maharashtra 400004

Global Steel And Engineering manufactures DBB plug valves in a range of sizes, materials, and pressure classes to meet industry requirements. 

Their valves provide a high-integrity positive shut-off and offer a safe and reliable alternative to the traditional two-valve system. 

Designed by international standards such as ASME, their DBB plug valves have become the industry standard in sectors like petroleum refineries, tank farms, and terminals.

Global Steel’s valves ensure online-verifiable sealing with high performance, making them suitable for oil and gas storage, movement, and other critical operations. 

With a wide selection of materials, pressure classes, and connection options, these valves are highly customizable to suit various applications.

#3: SHINJO

Location: 5A Floor, No 789, Wanhangdu Road, Jingan District, Shanghai, China

Shinjo specializes in DBB plug valves that offer non-lubricated and resilient sealing features. 

Their valves utilize a mechanical method to retract the plug before rotation, ensuring minimal contact between the plug and body during operation. 

This innovative design reduces wear and tear on the valve, allowing for a longer lifespan and more reliable operation.

Shinjo’s DBB plug valves are used in industries like oil, gas, chemical, and electric power systems. 

With a wide variety of industrial applications, their valves ensure precise control, durability, and leak-proof performance.

 Shinjo’s services also include on-site installation and technical support, making it a comprehensive solution provider in the industrial valve market.

#4: Valves Corporation

Valves Corporation is known for its friction-free double block and bleed plug valves that meet the market demand for space-saving low-maintenance solutions. 

Their DBB plug valves offer 100% bubble-tight sealing both upstream and downstream, achieved through a mechanically energized seal. 

This unique design eliminates the need for springs or other moving parts, resulting in a frictionless operation.

#5: Puffer-Sweiven

Location: 4230 Greenbriar Dr, Stafford, Texas 77477

Puffer-Sweiven manufactures high-integrity DBB plug valves designed for applications such as product isolation, blending, and custody transfer. 

Their valves are widely used in terminal and storage facilities where zero leakage is critical. 

These valves offer a verifiable zero-leakage guarantee, which makes them ideal for industries where precision and safety are paramount, such as aviation fueling and multi-product manifolds.
