Forged Steel 2-pc Ball Valve Class 150-1500 Floating Ball Flanged

Forged Steel 2-pc Ball Valve Class 150-1500 Floating Ball Flanged



With all advantages of floating ball valves, KOLINK forged steel floating ball valves are offered in types of 2-piece split body & 3-piece bolted body. The forging material ensures sufficient rigidity and strength under maximum rated operation pressure, without inherent flaw of cast materials. Standard wall thickness of valve body, and high strength bolts are sufficient to stand the pipe pressure. The internal parts of valve are designed and selected to ensure reliability under all kinds of work conditions.


With forged materials for improved mechanical properties, pressure retention, and quality, forged steel floating ball valves are ideal for medium or high pressure services and wide temperature range, and could replace small size trunnion-mounted ball valves.


Forged Steel Floating Ball Valves are in an extensive range of designs, materials, sizes, pressure classes and end connections. Cryogenic and high temperature metal seated configurations are also available.



Design Features:

1. Special Seat Design
The floating ball valve are normally designed with a flexible seat. When the medium pressure is low, the contact area between the seat and ball is smaller, which forms a higher pressure at the contact area to ensure reliable sealing. When the medium pressure gets higher, the contact area of the seat and ball becomes bigger along with the elastic deformation of the seat, so that the seat could endure higher medium thrust without being damaged.



2. Fire-safe Design
In case the fire accidently occurs in the pipe and valve, the seat ring made of PTFE or other non-metallic materials could be burned down under high temperature, causing massive leakage to the valve. The fire-safe seat design is a precaution design between the ball and seat. After the valve seat is burned away, the medium pressure would push the ball continuously towards the downstream metal seal to form an auxiliary metal-to-metal sealing, which could effectively reduce valve leakage. In addition, the middle flange sealing gasket is made of metal spiral-wound gasket, which could also ensure sealing under high temperature. The fire-safe design of KOLINK ball valves are approved per API 607.


3. Blowout-proof and Sealing Of Stem
The stem is machined with an integral collar at its bottom end, and it is installed from the valve inner cavity, so that the stem is blocked by the valve neck and would not be blown out by the medium even under the abnormal pressure-rising condition in the valve cavity. In addition, to avoid leakage after the stem packing is burned down in case of fire, the thrust washer between the stem shoulder and body contact would form a positive sealing. The sealing force would increase with the increase of medium pressure, to ensure reliable stem sealing under various pressure, preventing leakage and avoiding accident spreading.


4. The chevron packing.

The chevron packing could effectively adjust the sealing pressure against medium pressure at the gland area, and make the sealing of stem packing more reliable.



5. Anti-static Structure
The ball valve is provided with anti-static devices and could form a static channel between the ball and body through the stem, to discharge the static electricity built up due to friction during the operation of the valve, to through the pipeline, avoiding fire or explosion that may be caused by electric spark and ensuring system safety.


6. Valve Locking Device
The manual ball valve could be locked in position when it is fully-open or fully-closed. The positioning piece with locking hole is designed to avoid valve misoperation, and it could also prevent valve opening or closing accidently caused by pipeline vibration or other unpredictable factors. It is effective especially for inflammable and explosive oil, chemical and medical pipelines or field tubing.


Furthermore, the head of the stem that is installed with the wrench adopts double-D design. When the valve is open, the valve wrench is parallel to the pipeline, and when the valve is fully closed, the wrench is perpendicular to the pipeline, so that the fully open and closed indications of the valve are unmistakable.
