Vacuum Fittings - Ball Valves - Tube Ends Series: Complete Guide

Explore the Vacuum Fittings - Ball Valves - Tube Ends Series, featuring high-performance ball valves with various tube-end connections for industrial fluid control in oil & gas, chemical, and water treatment applications.

Product Overview

Ball Valves - Tube Ends combine the functionality of a ball valve with specific tube-end connection methods. The ball valve controls fluid flow by rotating a spherical disc, while the tube-end design determines how the valve connects to piping systems. These valves are widely used in oil & gas, chemical processing, water treatment, food & beverage, and power generation industries for flow isolation, distribution, and directional control.

Product Structure & Features

Ball Valve Components

Ball – Typically made from stainless steel, carbon steel, or alloy materials, with precision machining for smooth operation. The ball has a bore that aligns with the pipeline for flow or blocks it when rotated 90°.

Seat – Provides a tight seal between the ball and valve body. Common materials include PTFE (Teflon), reinforced polymers, or metal for high-temperature applications.

Stem – Connects the ball to the actuator (handle, gear, or pneumatic/electric operator). Made from hardened steel or stainless steel with anti-corrosion coatings.

Sealing Packing – Prevents leakage around the stem. Graphite or PTFE packing ensures long-term sealing performance.

Tube End Connection Types

Flanged Ends – Features ANSI/ASME/DIN standard flanges for bolted connections. Ideal for high-pressure and large-diameter piping systems.

Welded Ends (BW/SW) – Butt-weld (BW) or socket-weld (SW) connections provide leak-proof sealing, suitable for high-temperature and high-pressure applications.

Threaded Ends (NPT/BSP) – Male or female threaded connections (NPT, BSP) for easy installation in low-pressure, small-diameter systems.

Clamp Ends (Tri-Clamp/Sanitary) – Hygienic clamp connections for food, pharmaceutical, and biotech industries, allowing quick disassembly for cleaning.

Key Performance Features

Excellent Sealing – Bubble-tight shutoff with low fugitive emissions, suitable for hazardous fluids.

Quick Operation – 90° rotation for full open/close, enabling fast flow control.

Low Flow Resistance – Full-bore design minimizes pressure drop, improving energy efficiency.

Long Service Life – Corrosion-resistant materials and robust construction ensure durability in harsh environments.

Wide Compatibility – Works with water, steam, oil, gas, chemicals, and slurries across various pressure & temperature ranges.

Applications

Oil & Gas – Wellhead control, pipeline isolation, refinery processes.
Chemical Processing – Acid, alkali, and solvent handling.
Water & Wastewater – Pump control, filtration systems.
Food & Beverage – Hygienic processing, CIP/SIP systems.
Power Plants – Steam, cooling water, and fuel control.

Technical Specifications (Ball Valves - Tube Ends Series)

FAQs: Ball Valves - Tube Ends Series

1. What industries use Ball Valves - Tube Ends?

These valves are used in oil & gas, chemical, water treatment, food processing, and power generation for reliable flow control.

2. How do I choose the right tube-end connection?

Options include 316 stainless steel, Hastelloy, and PTFE-lined valves for acids, alkalis, and aggressive chemicals.

5. How do I maintain a ball valve with tube ends?

Lubricate the stem periodically.

Check seals & seats for wear.

Operate the valve occasionally to prevent sticking.

6. Can these valves handle high temperatures?

Yes, metal-seated ball valves can withstand up to 600°C (1112°F), depending on materials.

7. Are food-grade options available?

Yes, sanitary ball valves with Tri-Clamp ends and electropolished surfaces meet FDA & EHEDG standards.

8. What causes leakage, and how to fix it?

Leaks may occur due to seat wear, stem damage, or improper installation. Replace seals or seats if necessary.

9. Can these valves be automated?

Yes, they can be fitted with pneumatic, electric, or hydraulic actuators for remote control.

10. How do I confirm valve compatibility with my piping?

Match size, pressure class, material, and connection type with your system specs. Consult our datasheets or contact support.
