Valve Configuration
Sweat Inlet
One sweat connection is designed for permanent soldered installation to compatible copper tubing.
Full Port Valve Body
The full port internal passage helps maintain flow through the valve while providing fast quarter-turn shutoff.
Sweat Outlet & Drain
The opposite sweat connection continues the copper piping run, while the integrated drain feature provides access for removing downstream water.
Construction Details
The Midland drainable ball valve is manufactured from durable lead-free brass for corrosion resistance and dependable service in compatible potable water systems.
The precision-machined full port bore helps reduce unnecessary pressure loss when the valve is fully open.
An integrated drain port allows downstream piping to be emptied without removing the valve, while sweat end connections provide secure permanent installation in copper piping systems.
Why Choose a Drainable Ball Valve?
Convenient System Draining
- Integrated drain feature
- Simplifies seasonal winterization
- Helps empty downstream piping
- Useful during maintenance
- Reduces need for additional drain fittings
Full Port Flow
- Full port internal passage
- Helps minimize flow restriction
- Suitable for straight-through flow applications
- Quarter-turn shutoff
- Designed for compatible potable water systems
Quarter-Turn Operation
Open Position
When the lever handle is aligned with the piping direction, the internal ball is generally positioned for full-open flow.
Closed Position
Rotating the handle approximately 90 degrees moves the internal ball to the closed position for system isolation.
Integrated Drain Function
Maintenance
The drain feature provides a convenient point for releasing water from the isolated downstream section before servicing connected piping or equipment.
Winterization
When properly installed and used, the integrated drain can help remove trapped downstream water as part of a seasonal freeze-protection procedure.
Sweat x Sweat Connection
Sweat Inlet
The inlet is designed to be soldered directly to compatible copper tubing using accepted sweat-joint installation practices.
Sweat Outlet
The outlet provides a second solder connection for continuing the copper piping run through the valve.
Typical Applications
Residential & Commercial Plumbing
- Potable water piping
- Building water supply systems
- Seasonal plumbing branches
- Equipment isolation points
- Copper plumbing installations
Maintenance & Utility Systems
- Drainable branch lines
- Winterization applications
- Mechanical room piping
- Utility water systems
- Light industrial water service
Drainable Valve vs. Standard Ball Valve
Drainable Ball Valve
A drainable ball valve combines normal shutoff operation with an integrated drain point that can be used to empty an isolated downstream section.
Standard Ball Valve
A standard ball valve provides system isolation but typically requires a separate drain valve or fitting if downstream draining is needed.
Full Port vs. Reduced Port
Full Port
A full port valve uses a larger internal passage intended to reduce restriction through the valve when fully open.
Reduced Port
A reduced-port valve uses a smaller internal opening and may create greater flow restriction depending on the piping application.
Our valve, fitting, and industrial product specialists can help review your valve size, FIP connection requirements, pressure rating, handle configuration, media compatibility, and application before you order.

What does SWT x SWT mean?
SWT x SWT indicates sweat connections on both ends for soldered installation with compatible copper tubing.
What sizes are available?
The supplied product information lists 1/2", 3/4", and 1" nominal sizes.
What material is the valve made from?
The supplied product information identifies lead-free brass construction.
What does full port mean?
Full port refers to a valve design with an internal flow passage intended to minimize restriction when the valve is fully open.
What is the drain port used for?
The integrated drain port allows water to be removed from the isolated downstream piping section during maintenance, servicing, or winterization.
Is this valve suitable for potable water?
Yes. The supplied product information identifies the valve as suitable for potable water applications.
How does the valve operate?
The valve uses a quarter-turn lever handle to move between open and closed positions.
Can the valve be installed in copper piping?
Yes. The sweat end connections are designed for soldered installation in compatible copper piping systems.
Is a drainable valve useful for winterization?
Yes. The integrated drain can help remove water from an isolated downstream piping section as part of an appropriate winterization procedure.
Is this valve intended for throttling?
Ball valves are generally best suited for full-open or full-closed service rather than routine throttling unless specifically approved for that use.
What should I verify before ordering?
Confirm nominal copper tube size, sweat connection requirements, potable water compatibility, pressure and temperature requirements, drain orientation, and available installation space before ordering.
Important Ordering & Installation Notes
- This listing is for a Midland Lead-Free Drainable Full Port Ball Valve with Sweat x Sweat connections.
- Available nominal sizes are 1/2", 3/4", and 1".
- Confirm copper tubing size and sweat connection compatibility before ordering.
- The supplied product information identifies this valve as suitable for potable water applications.
- Verify lead-free brass compatibility with the intended water service.
- Confirm system pressure and operating temperature requirements before installation.
- Install using accepted soldering practices appropriate for copper piping.
- Protect internal valve components from excessive heat during soldering.
- Verify the drain port is oriented so it remains accessible after installation.
- Depressurize the piping system before opening or servicing the drain.
- Use the drain feature only after the appropriate section of piping has been isolated.
- For winterization, ensure downstream piping is properly drained according to system requirements.
- Ball valves are generally intended for full-open or full-closed service unless specifically approved for throttling.
