GMK Orbit Plug Valve / DBB PLUG VALVE

Product Overview of Double Block and Bleed Plug Valve

The Double Block and Bleed Plug Valve is designed for critical pipeline applications requiring reliable isolation, safe operation, and long-term sealing performance. It is widely used in industries such as oil and gas, chemical processing, fertilizer, power generation, and other demanding industrial systems.

Featuring an advanced orbit plug design, this valve provides reliable double isolation and bleed functions in a single valve body. Compared with conventional gate and ball valves, the Double Block and Bleed Plug Valve offers excellent sealing performance, reduced maintenance requirements, and extended service life.

The sealing system uses precision sealing rings around the valve disc to ensure reliable shut-off performance. The special groove structure and fixed sealing rings provide additional protection, improving durability under harsh operating conditions.

DESCRIPTION

Advanced Orbit Plug Valve Design and Double Block and Bleed Function

The Orbit Plug Valve adopts a unique operating mechanism that separates the valve disc from the seat during opening and closing. This design eliminates friction between the sealing surfaces and prevents unnecessary wear.

When the handwheel is operated, the plug first moves upward, separating the disc from the valve seat. The plug then rotates the disc by 90 degrees until the flow passage aligns with the valve body passage, allowing the valve to open completely.

During closing operation, the plug rotates the disc toward the closed position and presses it securely against the seat, creating reliable sealing performance.

This friction-free operation provides:

Reduced sealing surface wear
Longer valve service life
Lower operating torque
Improved sealing reliability

Reliable Double Block and Bleed Function

This valve provides double isolation and cavity pressure relief functions, making it an ideal solution for pipeline systems requiring enhanced safety.

Its key advantages include:

Double block and bleed capability
Safe pressure release from the valve cavity
Internal leakage detection
Online maintenance capability
Improved pipeline safety

This design helps reduce plant downtime and lowers lifecycle costs by minimizing maintenance requirements.

Full Bore Design for Efficient Flow Performance

The valve features a full bore flow passage design. When fully opened, the plug channel aligns directly with the valve body passage, minimizing pressure loss and improving flow efficiency.

Benefits include:

High flow capacity (CV)
Reduced erosion risk
Improved pumping efficiency
Lower pressure drop

The optimized flow path makes this Full Bore Plug Valve suitable for demanding pipeline applications.
