Specialityvalve is the top Double Block and Bleed Plug Valve Manufacturer in India. Double block and bleed valves are used to block a pipe portion on both sides of the valve rather than just one. It implies we may close the ball valve to stop both the upstream and downstream sides of the pipe from operating and bleed the leftover pressure. Installation time, pipe system weight, and space are reduced by using a single double block and bleed valve system rather than three separate valves. It also minimizes the number of leak channels to the atmosphere, lessening the danger, which is why many oil and gas firms have made it mandatory for field equipment maintenance.

Industries that use Double Block and Bleeding valve

• Oil & Gas Industry
• Chemical Industry
• Petrochemical Industry
• LNG and Natural Gas industrial processes Industry

Advantages of double Block and Bleed Valve

• Seals the valve against pressure from both the upstream and downstream ends.
• The ability to exhaust the space between the two block valves.
• Ensure low risk of hazard. Improved operational safety.
• When compared to a traditional design with separate valves, there is a significant space savings.
• Prevent contamination of the product.
• It can be cleaned or repaired.



The valve’s primary function is to

• to drain and/or vent the space produced by two isolation valves
• rerouting or divert the flow
• Have connection between the sampling and injection points
• It monitors leakage, conduct an integrity or maintenance check on the connection.

Plug Valve
Specialityvalve is the top Plug Valve Manufacturer in India. It is shaped like a cylinder or cone used to control the flow of fluids by rotating it inside the valve body itself. The plug has a straight through full port opening and can be used in on-off basic moderate throttling, and diverting services. It is used in place of a gate valve when quick operation is required.

Non-Lubricated Plug Valve
Specialityvalve is a well-known Non-lubricated Plug Valve Manufacturer in India. It's employed in regions where there isn't a lot of upkeep. It aids in the movement of medium without it becoming trapped and hardened, causing the valve to jam. A plug valve is a cylindrical or cone-shaped valve that rotates within the valve body to regulate the flow of fluid (medium). One or more hollow tubes are frequently arranged horizontally with plug valves to ease flow while the valve is open. When open, this bored tunnel is parallel to the flow. When the plug valve is turned 90 degrees, the solid plug portion blocks flow. It is used in place of a gate valve when quick operation is required. It works well in high-pressure, high-temperature environments.

Lubricated Plug valve
Specialityvalve is best Lubricated Plug valve manufacturer in India. Lubricants or sealants are used in lubricated plug valves to make operation easier over a wide range of operating pressures. The Lubricants film is used between the plug and the body. It requires lubricant injection on regular basis. The lubricant must not be washed away by the fluid flow, must not contaminated the fluid, and must be able to sustain line temperatures. Plastic sealants are used in the plug valves. It is essential to use effective sealant with properties like resistance, elasticity and ability to make a seal around each body part. The lubricant coating prevents corrosion on the metal surface between plug and the body.

Jacketed Plug Valve
Specialityvalve is the top Jacketed Plug Valve Manufacturer in India. The jacket and the valve body of a Jacketed Plug valve are separated by a gap. Any type of material can pass across the gap. This plug valve has a low flow resistance and performs well when sealed. The flow of the medium in the valve is controlled by a stopper. The plug moves from its seat to start the flow of the medium, and the plug returns to the valve seat to halt the flow. Jacketed Plug Valves are utilized in place of gate valves when a quick action is required in an application. This type of valve is widely utilized in situations involving high pressure and high temperature.
