Product Overview

The 3 Piece Flanged Stainless Steel Ball Valve is a premium-grade, full-port isolation valve designed for reliable on/off control in water, yağ, qaz, and food-grade applications. Manufactured from high-quality stainless steel (SUS304 / SUS316L) with precision investment casting, this valve offers exceptional corrosion resistance, davamlılıq, and hygienic performance. The 3-piece body design enables easy in-line maintenance — the center section can be removed without disturbing the pipeline connections. Available in sizes from DN15 to DN150 (1/2″ to 6″) with flanged ends and PTFE/PPL seats, this valve delivers bubble-tight shut-off (Class VI sealing) at temperatures up to 200°C. The full-port design ensures minimal pressure drop and maximum flow capacity. With FDA GRAS (Generally Recognized As Safe) compliance for food-contact applications and OEM/ODM customization support, this valve is the trusted choice for chemical processing, yemək & içki, pharmaceutical, water treatment, və sənaye boru sistemləri.

Tez-tez verilən suallar

Q1: What is the difference between a three-piece ball valve and a one-piece or two-piece ball valve?

A: A three-piece ball valve consists of three body components (two end caps and a central body) bolted together; the central body can be removed for maintenance or seal replacement without disconnecting the pipeline flanges. In contrast, one-piece and two-piece ball valves must be completely removed from the pipeline for maintenance. The three-piece design is particularly suitable for food, pharmaceutical, and chemical applications that require regular maintenance and cleaning.

Q2: What is the difference between PTFE and PPL seats?

A: PTFE (polytetrafluoroethylene) seats offer low friction, excellent chemical resistance, and a temperature range of -20°C to +200°C, making them suitable for most food and chemical applications. PPL (reinforced PTFE) offers superior wear resistance and pressure-handling capabilities, making it suitable for applications involving higher pressures and more frequent operation.

Q3: What does FDA GRAS compliance mean?

A: FDA GRAS (Generally Recognized As Safe) is a safety certification from the US FDA for food-contact materials. All materials in this valve that come into contact with the process medium comply with FDA GRAS standards, ensuring safety for fluid handling in food, içki, dairy, and pharmaceutical production.

Q4: Can this valve be used for steam applications?

A: This valve comes standard with PTFE seats, rated for a maximum temperature of 200°C. For steam applications (saturated steam), it is recommended to verify that the operating temperature does not exceed the seat’s rated limit. If higher temperatures are required, PPL seats or metal-to-metal sealing options are available.
