THREE PIECE BALL VALUE

THREE-PIECE BALL VALVE

Product Overview

The THREE-PIECE BALL VALVE is a highly versatile and maintenance-friendly industrial valve designed for superior flow control and reliability. Distinguished by its modular three-part body construction, this valve features a center section held together by two end caps and tie bolts. This design allows for easy disassembly and maintenance—such as seat and seal replacement—without the need to remove the entire valve assembly from the pipeline. This "in-line repairability" significantly reduces downtime and operational costs, making it an ideal choice for critical process applications.

Engineered for durability, the valve offers robust performance in high-pressure and high-temperature environments. The body is typically constructed from CF8/CF8M (Cast Stainless Steel 304/316), providing excellent corrosion resistance and structural integrity. The internal components, including the ball and stem, are precision-machined to ensure smooth operation and tight shut-off, while the reinforced PTFE (RPTFE) seats guarantee long-term sealing reliability.

Key Features & Benefits

• Modular Design: The three-piece structure facilitates easy cleaning, maintenance, and part replacement without disturbing the pipeline connections.

• High Durability: Constructed with high-grade stainless steel (CF8/CF8M) and reinforced PTFE seals to withstand harsh industrial environments.

• Versatile End Connections: While the standard configuration shown is threaded (NPT/BSP), the design concept often accommodates butt-weld or other connections for seamless integration.

• Locking Device: Equipped with a locking device on the handle to prevent unauthorized or accidental operation, ensuring safety in industrial settings.

• Fire-Safe Design: The metal-to-metal secondary seal design provides a safety backup in case the primary soft seals are damaged by fire.

Technical Specifications

Our Three-Piece Ball Valves are available in a comprehensive range of sizes to meet diverse industrial requirements, from small instrumentation lines to larger process piping.

• Size Range: Available from DN6 (1/4") to DN100 (4").

• Pressure Rating: Designed to handle standard industrial pressure ratings (e.g., 1000 WOG).

• Connection Type: Female Threaded (BSP/NPT) as per standard specifications.

• Operation: Manual lever handle for sizes up to DN50; gear operation is typically available for larger sizes (DN65-DN100) to ensure ease of use.

Material Composition

The valve is engineered using a combination of high-quality materials to ensure compatibility with various media, including water, oil, gas, steam, and corrosive chemicals.

• Body & Cap: CF8 / CF8M (Stainless Steel 304 / 316)

• Ball: CF8M (Stainless Steel 316) for superior corrosion resistance.

• Stem: Stainless Steel 304 / 316, designed with a blow-out proof structure.

• Seats & Seals: Reinforced PTFE (RPTFE) and PTFE, offering excellent chemical resistance and low friction.

• Fasteners: High-tensile Stainless Steel 304 bolts and nuts.

Applications

Ideal for use in the petrochemical, refining, chemical, pulp & paper, and power generation industries. Its ability to handle aggressive media and high pressures makes it a preferred choice for process control systems where reliability and maintenance accessibility are critical.
