floating ball valve

Floating ball valve is one of the most widely used types of ball valves. Its core feature is that the sphere is in a "floating" state inside the valve chamber, and is only radially positioned through the upper and lower valve stems. Under the action of medium pressure, the sphere can produce small displacement and tightly press the sealing ring at the outlet end, thus achieving one-way sealing. The floating ball valve has a simple and compact structure, mainly composed of a valve body, a floating ball body, a valve seat (sealing ring), a valve stem, and a driving device. Its working principle is to operate the handle or actuator to drive the valve stem to rotate the ball 90 °, and use the opening or closing of the ball's through-hole to control the flow channel. The main advantages of the internal thread floating ball valve, external thread welded pipe floating ball valve, forged steel floating ball valve, flange floating ball valve, electric floating ball valve, pneumatic floating ball valve, turbine floating ball valve, clamp floating ball valve, insulation floating ball valve and other floating ball valves produced by Kaiweixi Valve include simple structure, small volume, light weight, low manufacturing cost, and low fluid resistance. It is usually suitable for medium and small caliber (DN ≤ 200mm) and medium and low pressure (such as Class 150/300) working conditions, and is widely used for cutting off water, oil, gas, and general corrosive media. It is an important basic switch valve in the fields of petroleum, chemical, urban water supply and drainage.

Q61F Forged Steel Three-Piece Ball Valve OverviewThe Q61F Forged Steel Three-Piece Ball Valve is a high-performance compact ball valve featuring a forged steel body with internal thread or butt weld connections. Its body consists of three segments connected by high-strength bolts. The valve is precision-machined from forged steel materials (e.g., A105), and the ball is rotated 90 degrees via the stem for quick opening and closing. The sealing pair utilizes soft materials such as PTFE or a metal hard-seal configuration. This design combines high-pressure capability with a compact installation footprint, making it specifically suitable for applications in petrochemicals, power plants, high-pressure instrumentation, and piping systems with limited space. It is an ideal choice for reliable shut-off in small-bore, high-pressure operating conditions.Q61F Forged Steel Three-Piece Ball Valve Product Image

Q61Y Forged Steel Three-Piece Ball Valve OverviewThe Q61Y Forged Steel Three-Piece Ball Valve is a high-performance hard-seal ball valve featuring a forged steel body and a three-piece bolted construction. The valve body is forged from high-strength materials such as A105 steel in three sections, which are securely assembled using alloy steel bolts. The sealing surfaces of the ball and seats employ hard-metal overlay welding, forming a durable metal-to-metal seal. The valve achieves reliable 90-degree opening and closing through the rotation of the stem, which drives a fixed ball design.This valve is specifically engineered for demanding applications involving high pressure, high temperatures, and abrasive or corrosive media. It combines the high pressure-bearing capability of forged steel, the easy maintenance enabled by the three-piece structure, and the durability of hard-sealed surfaces. It is widely used in critical high-pressure, small-bore pipelines across industries such as petrochemicals, natural gas, power generation, and other vital industrial facilities.Q61Y Forged Steel Three-Piece Ball Valve

Q61N Forged Steel Butt-Weld Ball Valve

Model：
Q61N-160P/Q61N-320P
Specification：
DN10-DN100
Pressure：
PN160,PN320
Material：
forged steel,forged stainless steel

Q61N Forged Steel Butt-Weld Ball Valve OverviewThe Q61N Forged Steel Butt-Weld Ball Valve is a high-performance, permanently sealed ball valve featuring an integrally forged steel body and butt-weld ends. The valve body is forged from materials such as A105 steel, with both ends designed for direct butt-welding to the pipeline, creating an integral connection that completely eliminates leakage risks associated with flanged joints. Utilizing a fixed-ball or floating-ball design, the valve typically incorporates metal hard seats or high-performance soft seats, achieving reliable 90-degree on/off operation through stem-driven rotation of the ball.This valve is specifically engineered for demanding service conditions involving high temperatures, high pressures, toxic fluids, or flammable and explosive media. It is widely used in critical applications across petrochemical plants, long-distance natural gas pipelines, power stations, and key process systems, serving as the essential isolation device for pipeline segments requiring absolute sealing integrity and operational safety.Q61N Forged Steel Butt-Weld Ball Valve Product Image
