TRUNNION

TRUNNION

Ball Valve Part: Trunnion The trunnion is a critical internal component of a trunnion-mounted ball valve, providing structural support and stability to the ball during operation. Unlike floating ball valves where the ball is held only by the stem and sealing forces, the trunnion acts as a fixed pivot point that anchors the ball firmly inside the valve body. Function of the Trunnion Support and Stability The trunnion supports the ball at the bottom (and sometimes top), preventing excessive movement during flow and pressure changes, especially in larger valves or high-pressure applications. Reduced Operating Torque By anchoring the ball, the trunnion reduces the stress on the valve seats, allowing smoother operation with less torque required to open or close the valve. Enhanced Sealing Performance Trunnion-mounted designs improve sealing reliability under high pressure and minimize wear on the seats by controlling ball movement. Key Features Typically made from durable materials such as stainless steel or carbon steel for strength and corrosion resistance. Mounted inside the ...

STEM

STEM

Ball Valve Part: Stem The stem is a vital component of a ball valve that connects the actuator or handle to the ball, enabling rotational movement to open or close the valve. It transmits the torque applied externally to rotate the ball inside the valve body, controlling flow through the pipeline. Function of the Stem Torque Transmission The stem transfers the turning force from the valve handle, gear, or actuator to the ball, causing it to rotate 90 degrees for on/off operation or partial rotation for throttling. Sealing Interface The stem passes through the valve body and must be sealed properly to prevent leaks. This is typically achieved through packing materials, O-rings, or gland seals. Alignment and Support Provides axial alignment between the actuator and the ball, ensuring smooth, precise valve operation. Key Features Material Usually made of stainless steel, carbon steel, or alloy steel to withstand mechanical stress and corrosion. Stem Types Blowout-Proof Stem : Designed to prevent the stem from being ejected under pressure. ...

SEAT

SEAT

Ball Valve Part: Seat The seat is a fundamental sealing component within a ball valve that ensures tight closure by pressing against the ball, preventing any fluid leakage. It plays a vital role in maintaining the valve’s sealing integrity and overall performance. Primary Function Sealing Interface Provides a reliable seal between the ball and valve body, ensuring leak-tight shutoff when the valve is closed. Wear Protection Cushions the ball, minimizing wear and extending the valve’s service life. Pressure Compensation Some seat designs adapt to pressure changes to maintain consistent sealing. Material and Design Common Materials Includes PTFE, reinforced PTFE, PEEK, and metals. Soft seats offer excellent sealing for lower temperatures and pressures, while metal seats withstand harsh conditions like high temperature and high pressure. Seat Types Floating Seats : Slightly movable to press against the ball for effective sealing. Trunnion Seats : Fixed ball with movable seats for heavy-duty applications. ...

FLANGE

FLANGE

Flange A flange is a critical component used to connect pipes, valves, pumps, and other equipment to form a secure, leak-proof piping system. It provides a reliable mechanical joint that allows easy assembly, disassembly, and maintenance of pipeline sections. Key Functions Connection Interface Flanges join two components together, enabling fluid flow continuity while maintaining system integrity. Ease of Maintenance Facilitates quick disassembly for inspection, cleaning, or repair without cutting the pipe. Seal Surface Works with gaskets to ensure a tight, leak-free seal between connected parts. Common Types Weld Neck Flange : Provides strong connection by welding to the pipe; suitable for high-pressure applications. Slip-On Flange : Slides over the pipe for simpler installation; used in low-pressure systems. Blind Flange : Used to close the end of a pipe or vessel. Socket Weld Flange : Pipe is inserted into the flange and welded; ideal for small diameter, high-pressure systems. Threaded Flange : Screwed ...

BODY

BODY

Ball Valve Part: Body The body is the main pressure-containing component of a ball valve, housing all internal parts such as the ball, seats, stem, and seals. It provides structural integrity and ensures reliable operation under various pressure and temperature conditions. Key Functions Structural Support The body encloses and supports internal components, maintaining alignment and sealing under operating conditions. Pressure Containment Designed to withstand internal pressure, preventing leaks and ensuring safety. Connection Interface Provides end connections to the piping system through flanges, threaded ends, or welding. Material and Design Typically made from carbon steel, stainless steel, alloy steel, or other corrosion-resistant materials selected based on process media and environment. Available in various designs such as one-piece, two-piece, or three-piece bodies, each offering different advantages in terms of maintenance and installation. Designed according to industry standards (ASME, API, DIN) to ensure durability and compatibility. ...

BALL

BALL

Ball Valve Part: Ball The ball is the central rotating component inside a ball valve that controls fluid flow. Shaped as a hollow sphere with a through-hole (bore), it allows flow when aligned with the pipeline and blocks flow when rotated 90 degrees to the closed position. Function of the Ball Flow Control Rotates within the valve body to open or close the passage, providing quick and reliable on/off control. Sealing Interface Works in conjunction with the valve seats to create a tight seal, preventing leakage when closed. Pressure Handling Designed to withstand system pressure and ensure smooth operation under various temperature and flow conditions. Key Features Material Commonly manufactured from stainless steel, carbon steel, chrome-plated steel, or other corrosion-resistant alloys for durability and corrosion resistance. Surface Finish Precision machining and polishing reduce friction and wear, enhancing sealing and operational life. Bore Types Full Bore : The bore diameter equals the pipeline diameter, mi ...

BALL SUPPORT

BALL SUPPORT

Ball Valve Part: Ball Support The ball support is an internal component designed to provide additional stability and alignment for the ball inside a ball valve, especially in larger or trunnion-mounted valve designs. It helps maintain the ball’s position during operation, reducing wear and improving sealing performance. Function of Ball Support Structural Stability Supports the ball at the bottom (and sometimes top), preventing excessive movement or displacement under high pressure or flow conditions. Enhanced Sealing By stabilizing the ball, it ensures consistent contact between the ball and seats, improving leak-tightness. Reduced Operating Torque Helps distribute forces evenly, decreasing the torque needed to operate the valve. Design and Materials Usually fabricated from durable metals such as stainless steel or alloy steel to withstand mechanical stress and corrosion. Integrated into the valve body or attached near the ball’s trunnion to provide firm support. Applications Common in large-diameter and high-pressure ball valves, ...
