CARACTERÍSTICAS ESTRUTURAIS

Special Seat Design

The floating ball valve features a flexible seal ring structure. At lower medium pressures, the contact area between the seal ring and the ball is smaller, creating a higher sealing ratio at the contact point. This design provides reliable sealing.

As the medium pressure increases, the contact area between the seal ring and ball expands due to the elastic deformation of the seal ring, allowing it to withstand higher medium thrust without damage.

Fireproof Structure Design

In the event of a fire, the seat ring, typically made of PTFE or other non-metal materials, may decompose or be damaged under high temperatures, leading to increased leakage. To address this, a fireproof seal ring is placed between the ball and seat. If the valve seat burns, the medium pushes the ball rapidly toward the downstream metal seal ring, forming an auxiliary metal-to-metal sealing structure.

Additionally, the middle flange sealing gasket is made of a metal-wound gasket, which maintains sealing even under high temperatures. The fireproof structure design of the floating ball valve complies with standards such as API 607, API 6FA, and BS 6755.

Reliable Sealing Of Valve Stem

The valve stem is designed with a shoulder at its base, preventing it from being blown out by the medium, even under extreme conditions such as abnormal pressure rise within the valve cavity or gland plate failure. To prevent leakage after stem packing burns during a fire, a thrust bearing is placed at the contact point between the stem shoulder and the body, forming a reverse sealing seat.

The sealing force of this reverse seal increases with the medium pressure, ensuring dependable stem sealing under various pressures, thus preventing leakage and avoiding the spread of accidents.

The stem uses a V-type packing sealing structure, which effectively converts the pressing force and medium force of the gland into the sealing force of the stem.

For additional reliability, a disc spring-loaded packing pressing mechanism can be used, based on user requirements.

Anti-static Structure

The ball valve is equipped with an anti-static structure that incorporates a static electricity discharge device. This device forms a direct static channel between the ball and body or creates a static channel through the stem, allowing static electricity generated by friction during the opening and closing of the ball and seat to discharge through the pipeline.

This feature helps prevent fires or explosions caused by static sparks, enhancing system safety.

Lock And Misoperation Prevention

The manual ball valve can be locked in either the fully open or fully closed position. A 90° open and close positioning piece with a lock hole is designed to prevent misoperation caused by unauthorized handle operation. It also helps avoid accidental valve opening or closing due to pipeline vibrations or other unpredictable factors.

This feature is particularly effective in environments with flammable and explosive substances, such as oil, chemical, and medical pipelines or field tubing. The handle installation on the stem’s head features a flat design. When the valve is open, the handle aligns parallel to the pipeline, providing accurate open and close indications without error.
