Valve Configuration

Female NPT Inlet

The inlet accepts a compatible male NPT pipe, nipple, fitting, or equipment connection.

Full Port Valve Body

The precision-machined internal passage helps maintain flow through the valve with minimal restriction when fully open.

Female NPT Outlet

The outlet provides a second female threaded connection for straightforward installation into compatible piping systems.

Construction Details

The Midland in-line full flow ball valve features an investment-cast 316 stainless steel body designed for strength, corrosion resistance, and dependable service in demanding piping environments.

A precision-machined 316 stainless steel ball and full port internal flow path help minimize unnecessary restriction and pressure loss when the valve is fully open.

The vinyl-coated locking lever handle provides quick quarter-turn operation and can be secured in the open or closed position when required by operating or maintenance procedures.

Why Choose 316 Stainless Steel?

Corrosion Resistance

  • 316 stainless steel body
  • 316 stainless steel ball
  • Suitable for demanding environments
  • Provides strong resistance to many corrosive conditions
  • Designed for long service life

Industrial Durability

  • Investment-cast valve body
  • High-pressure 1000 WOG rating
  • Precision-machined internals
  • Durable threaded connections
  • Suitable for repeated operating cycles

Full Port Design

Maximum Flow Capacity

The full port internal passage is designed to maintain a flow opening similar to the connected piping, helping reduce restriction through the valve.

Reduced Pressure Loss

A larger internal bore can help reduce pressure drop compared with reduced-port valve designs in compatible applications.

Locking Handle Operation

Quarter-Turn Control

The lever handle rotates approximately 90 degrees between the fully open and fully closed positions for quick manual shutoff.

Locking Capability

The handle is designed to be secured in the open or closed position when required for operational control, maintenance procedures, or site-specific safety practices.

Typical Applications

Commercial Piping

  • Building mechanical systems
  • Water and utility piping
  • Equipment isolation
  • Maintenance shutoff points
  • Compatible fluid handling systems

Industrial Systems

  • Process piping
  • Plant utility systems
  • Industrial equipment connections
  • Corrosive service applications where compatible
  • High-pressure fluid systems within valve ratings

Full Port vs. Reduced Port Ball Valve

Full Port

A full port valve uses a larger internal passage intended to minimize flow restriction and pressure loss when the valve is fully open.

Reduced Port

A reduced-port valve uses a smaller internal opening and may create greater flow restriction depending on the piping application.

Frequently Asked Questions

What material is the valve body made from?

The supplied product information identifies an investment-cast 316 stainless steel body.

What material is the ball?

The supplied product information identifies a 316 stainless steel ball.

What type of connections does the valve use?

The valve uses female NPT threaded connections on both ends.

What does full flow mean?

Full flow, also called full port, indicates an internal passage designed to minimize restriction through the valve when fully open.

What is the pressure rating?

The supplied product information identifies a pressure rating of up to 1000 WOG.

What does WOG mean?

WOG is commonly used to indicate a pressure rating for water, oil, and gas service under appropriate operating conditions.

Does the valve have a locking handle?

Yes. The supplied product information identifies a vinyl-coated locking lever handle.

Can the handle be locked open or closed?

Yes. The supplied product information states that the handle can be secured in either the open or closed position.

How does the valve operate?

The valve uses quarter-turn operation between the fully open and fully closed positions.

Is the valve intended for throttling?

Ball valves are generally best suited for full-open or full-closed service unless the specific valve and application are approved for throttling.

What should I verify before ordering?

Confirm nominal pipe size, female NPT thread compatibility, pressure requirements, temperature limits, media compatibility, and installation requirements before ordering.

Important Ordering & Installation Notes

  • This listing is for Midland 316 Stainless Steel In-Line Full Flow Ball Valves with locking handles.
  • The supplied product information identifies 316 stainless steel body and ball construction.
  • Connections are Female NPT x Female NPT.
  • The supplied pressure rating is up to 1000 WOG.
  • Confirm the required nominal pipe size before ordering.
  • Verify NPT thread compatibility with the intended piping components.
  • Confirm media compatibility with all valve body, ball, seat, seal, and packing materials.
  • Verify pressure and temperature requirements before placing the valve into service.
  • Use appropriate thread sealant or PTFE tape where permitted by the application.
  • Avoid excessive installation torque that could damage the threaded connections or valve body.
  • Apply installation torque to the appropriate valve body area rather than using the handle as leverage.
  • Confirm adequate clearance for full lever travel.
  • Use the locking feature only in accordance with site operating and safety procedures.
  • Ball valves are generally intended for full-open or full-closed service unless specifically approved for throttling.
  • Install according to applicable piping standards, project requirements, and manufacturer recommendations.
