Stainless Steel Ball Valve

3-Piece Threaded Ball Valve
The 3-Piece Threaded Ball Valve is widely regarded as the most versatile and durable manual isolation valve in industrial piping. Its defining characteristic is its modular three-piece construction, consisting of one central body and two end caps. This design is specifically engineered for systems that require frequent cleaning, inspection, or seat replacement without disturbing the entire pipeline.
As a leading industrial valve manufacturer, WODE Valve offers these in high-grade 316 and 304 Stainless Steel, providing exceptional resistance to corrosion and wear. The threaded ends (NPT/BSP) allow for quick, secure installation in a wide variety of commercial and industrial applications, ranging from chemical processing to food and beverage production.

Product Description

Key Features & Benefits

· In-Line Maintenance Capability: The central housing can be swung out or removed by simply loosening the bolts, leaving the pipe connectors in place. This dramatically reduces downtime during routine servicing.

· Full Port (Full Bore) Design: The internal diameter of the valve matches the pipe's I.D., ensuring maximum flow capacity and minimizing pressure drop.

· High Pressure & Temperature Rating: Typically rated for 1000 PSI (WOG) and capable of withstanding temperatures from -29°C to 200°C, making it suitable for demanding thermal environments.

· Blow-out Proof Stem & Anti-Static Device: Engineered for safety, the stem is designed to remain secure under high pressure, while anti-static features prevent discharge in volatile gas or liquid lines.

· Lockable Handle: Includes a stainless steel lever with a locking mechanism to prevent accidental or unauthorized operation.

· ISO 5211 Mounting Pad: Available on high-performance models to allow for easy installation of electric or pneumatic actuators for automated flow control.

Why 3-Piece is the Preferred Choice for OEMs

Choosing a 3-Piece Threaded Ball Valve over 1-piece or 2-piece alternatives offers significant long-term value:

· Cost-Effectiveness: While the initial cost is higher, the ability to replace internal components like seats and seals instead of the whole valve reduces the total cost of ownership.

· Ease of Welding: For welded versions, the center body can be removed to prevent heat damage to the soft seats during the installation process.

· Hygiene & Cleaning: Favored in sanitary applications because the valve can be fully disassembled for deep cleaning to prevent media contamination.

Industrial Applications

· Chemical Processing: Handling corrosive acids and chemical reagents with 316SS integrity.

· Food & Beverage: Used in breweries and dairy processing for easy-to-clean fluid paths.

· Pharmaceuticals: Reliable isolation for high-purity liquid transport.

· Oil & Gas: Control of auxiliary lines and sampling systems.

· Water Treatment: Robust performance in municipal and industrial filtration loops.
