LT Ball Valve

Product Details:

L&T (Larsen & Toubro) manufactures two-piece ball valves as part of their valve product line. Two-piece ball valves are a type of ball valve that consists of two main parts: the body and the cap, which are bolted together. These valves are widely used in various industrial applications for their durability, reliability, and ease of maintenance. Here is some information about L&T's two-piece ball valves:

1. Design: Two-piece ball valves are designed based on the ball valve principle, utilizing a spherical ball with a hole (bore) through it to control fluid flow. Rotating the ball 90 degrees using a handle or actuator allows for precise flow control, from fully open to fully closed.

2. Materials: L&T manufactures two-piece ball valves using a variety of materials to suit different applications. Common materials include stainless steel, carbon steel, and other alloys. The choice of material depends on factors such as the fluid being handled, temperature, and pressure requirements.

3. Pressure Rating: L&T's two-piece ball valves come in different pressure ratings to meet various system demands, ranging from low-pressure to high-pressure applications.

4. Temperature Range: These valves are designed to operate across a wide range of temperatures, making them suitable for both cryogenic and high-temperature applications.

5. Sizes: L&T offers two-piece ball valves in various sizes to accommodate different pipe diameters and flow rates, catering to a wide range of industrial needs.

6. Applications: L&T's two-piece ball valves find use in diverse industries, including oil and gas, petrochemicals, power generation, water treatment, and manufacturing. They are suitable for applications requiring precise flow control, tight sealing, and fluid isolation.

7. Types: L&T manufactures different types of ball valves, including floating ball and trunnion ball designs, to meet specific application requirements. The choice of valve type depends on factors such as pressure, temperature, and the nature of the fluids.

8. Maintenance: Routine maintenance is important to ensure the proper operation and longevity of L&T's two-piece ball valves. Maintenance tasks may include lubrication, inspection, and the replacement of seals or seats as needed.

9. Installation: Proper installation is crucial for the performance and integrity of two-piece ball valves. They should be installed according to industry standards, ensuring correct alignment and torque for the fasteners.

10. Accessories: L&T's two-piece ball valves can be equipped with various accessories, such as actuator motors, handwheels, or gear operators, to facilitate valve operation, especially in larger sizes or in automated systems.

When selecting an L&T two-piece ball valve for a specific application, it's essential to consider factors such as the type of fluid or gas, temperature and pressure requirements, material compatibility, and system design. Consulting with L&T's valve experts or authorized distributors can help you choose the right two-piece ball valve to meet your specific needs.

Trunnion Mounted Ball Valve is the preferred choice of ball valve in higher sizes and pressure ratings, and incritical process applications requiring special capabilities. In this design, sealing takes place by allowing the seat to movetowards the ball along the flow axis, which leads to lower operating torques over other types of valves. The valves haveadvanced design features such as a built-in cavity relief mechanism, compact internal trunnion holder, and intrinsic doubleblock and bleed facility. The valves are of two-piece design, bolted at the body connection joint and with flanged or butt weldends, and are available in both reduced bore and full bore designs. BENEFITS• Proven Double Block and Bleed featureArgus Trunnion Mounted Ball Valves aredesigned for upstream sealing, so that the doubleblock and bleed feature is automatically built in.The feature enables on-line affirmation of properseat sealing.• Enhanced stem seal life, low wear on seatsThe reaction generated by the line fluid load onthe ball is absorbed by the trunnion bearings anddirectly transmitted to the valve body. The valvestem is hence free from any bending load whichleads to reduced stem friction torques andenhanced stem seal life.The seat rings are allowed to move in the flowaxis against a fixed ball so that the line pressureassists in pressing the spring-loaded upstreamseat against the ball. Thus, the operating torqueand wear on the seats is relatively low, enhancingseat life.• High-integrity seat and stem sealing systemsThe soft-seated valve designs use PTFE or othersuitable elastomers as the primary seatingmaterial. These seats are designed to ensurefull leak-tightness. Both upstream anddownstream sealing are assisted by seat-loadingmechanisms consisting of retainer, spring, ‘O’ ringand wedge ring, which continuously press theseats against the ball.• Automatic cavity relief featureThe seat design of Argus T-Series Trunnionmounted Ball Valves has a built-in automaticcavity relief mechanism. In the event of excessivepressure build-up inside the cavity, the springsthat keep the seats pressed to the ball arepressed back by the seat, allowing the releaseof excessive pressure. This eliminates the needfor having external cavity relief assemblies.• Blowout-proof stem• Internal trunnion holderThe internal trunnion/bearing holders in the valveeliminate many drawbacks arising from valvedesigns that feature external trunnion/bearingholders.• Fire-safe by design, to meet requirement ofAPI 607 for soft seated valves• Compliance to NACE (optional) TR15 / TF15 (Class 150) / TR30 / TF30 (Class 300)Alternate materials like SS and Alloy Steel are available.Special seat materials available on request.
