Ball Valve Connection Types – Choose the Right End for Leak-Free Performance

Ball valve selection is more than material and size—connection type plays a major role in installation, sealing reliability, system pressure, and maintenance. At Perfect Engineers, we offer every standard ball valve end connection used in India and worldwide, whether you’re dealing with screwed lines, flanged manifolds, sanitary tubing, or welded pipework.

In this guide, you’ll learn all about the different ball valve connection types, their ideal applications, advantages, and how to select the best one for your system.

Why Are Valve Connection Types Important?

  • They determine how the valve integrates with your pipeline
  • Influence sealing type (thread, gasket, weld)
  • Impact pressure & temperature rating
  • Affect installation and maintenance speed
  • Must match international piping standards (ANSI, DIN, BSP, NPT)

Common Ball Valve Connection Types

Threaded Ball Valves

Types: BSP (British Standard), NPT (American Standard), BSPT (tapered)
Sizes: ½” to 2”
Features:

  • Easy installation (no welding or flanges)
  • Ideal for smaller pipelines
  • PTFE tape or thread sealant required

Best For:

  • Compressed air, water, oil
  • HVAC & domestic plumbing
  • Instrumentation lines

Flanged Ball Valves

Standards: ANSI B16.5, DIN PN10/16/40, JIS 10K
Sizes: ½” to 12”
Features:

  • Leak-tight connection using bolts + gasket
  • Can be disassembled for maintenance
  • Ideal for heavy-duty and high-pressure lines

Best For:

  • Oil & gas, chemicals, power plants
  • Steam and thermal systems
  • Refineries and process skids

Welded Ball Valves

Definition:

  • Socket weld: Pipe fits inside the valve socket
  • Butt weld: Pipe and valve ends are beveled for direct weld

Features:

  • Strongest, most permanent joints
  • No leakage points
  • High-pressure and high-temperature capable

Best For:

  • Boiler lines
  • Steam and condensate headers
  • Gas and heat transfer fluids

Compression Fitting Ball Valves

Definition: Valve has compression ends compatible with tubes and instrument fittings

Best For:

  • Instrumentation panels
  • Skid-based dosing systems
  • Low-pressure gas or fluid control

Materials: SS316, Brass
Size: ¼” to 1”

Quick Comparison Table

Connection Type Install Ease Pressure Rating Reusable? Best For
Threaded Easy Medium Yes Utility, HVAC
Flanged Medium  High Yes Process piping
Socket Weld Complex  Very High No Steam, high pressure
Tri-Clamp Easy  Low–Med Yes Food, pharma
Compression End Easy  Low Yes Instrumentation

Optional Ends & Custom Variants

  • Hose Barb End: For flexible hose piping in agriculture & food
  • Extended Weld End: For jacketed valves or insulated lines
  • Fully Welded Body (No external joints): For underground or tamper-proof use
  • Dual Connection (e.g., Flange x Threaded): For retrofit or hybrid systems

FAQs – Ball Valve End Connections

Yes. Simply unbolt, replace gasket, and reinstall.

No. Welded valves are separate types. Welding a flanged valve ruins the face.

Yes. It handles higher pressure, eliminates leakage risks.

Yes, if media is clean and pressure is under 10 bar. Ideal for clean applications.

Buyer Tip: Always Match Standards

  • Use ANSI B16.5 valves for American piping
  • Use PN10/16/40 for DIN-standard pipelines
  • For dairy/pharma, always ask for tri-clamp or SMS ends
  • For long-term install with no access, use welded valves
  • For testing lines or skids, use compression/ferrule ends
