Valve Configuration
Restrained Joint Inlet
One RT connection provides a restrained mechanical joint for compatible underground piping systems.
Resilient Wedge Body
The internal resilient seated wedge moves through the valve body to provide full-open flow or dependable shutoff.
Restrained Joint Outlet
The opposite RT connection continues the underground piping run while helping maintain joint restraint.
Construction Details
The Midland RT x RT gate valve uses a heavy-duty ductile iron body designed for strength and durability in demanding underground water distribution applications.
A resilient seated wedge provides dependable sealing performance, while the non-rising stem keeps operating movement contained within the valve assembly.
Restrained joint end connections help provide a secure mechanical connection where underground piping systems require joint restraint.
Why Choose a Restrained Joint Gate Valve?
Secure Underground Connection
- RT x RT restrained joint ends
- Designed for underground piping systems
- Helps maintain joint restraint
- Suitable for municipal water installations
- Reduces reliance on flanged connections
Dependable Isolation
- Resilient seated wedge
- Bubble-tight shutoff design
- Non-rising stem configuration
- Heavy-duty ductile iron body
- Corrosion-resistant exterior protection
Non-Rising Stem Design
Compact Operation
The non-rising stem remains within the valve assembly as the valve is opened and closed, reducing the vertical clearance required for operation.
Below-Grade Service
The compact stem arrangement is well suited for underground installations where the valve is operated from grade through a valve box, extension, or compatible post indicator system.
Standard 2" Operating Nut
Below-Grade Operation
The standard 2" operating nut allows the valve to be opened and closed using compatible underground valve operating equipment.
Service Access
The operating nut can be accessed through an appropriate valve box or other approved access arrangement after installation.
Typical Applications
Municipal Water Systems
- Water distribution mains
- Utility water systems
- Municipal service lines
- Underground isolation points
- Distribution network valves
Commercial & Underground Systems
- Commercial water distribution
- Site utility piping
- Underground mechanical systems
- Property water mains
- Compatible buried piping systems
Restrained Joint vs. Threaded Connection
Restrained Joint
A restrained joint connection is designed to mechanically secure compatible piping and help resist separation forces in underground installations.
Threaded Connection
A threaded connection joins compatible pipe and fittings through mating threads and is typically used in different piping arrangements and size ranges.
Gate Valve vs. Ball Valve
Gate Valve
A gate valve uses multi-turn operation to raise or lower a wedge and is primarily designed for full-open or full-closed isolation service.
Ball Valve
A ball valve typically uses quarter-turn operation for faster shutoff and is commonly used in smaller piping systems or applications requiring rapid operation.
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 RT x RT mean?
RT x RT indicates restrained joint connections on both ends of the valve.
What sizes are available?
The supplied product information identifies sizes from 2-1/2" through 8".
What material is the valve body made from?
The supplied product information identifies heavy-duty ductile iron construction.
What is a resilient seated gate valve?
A resilient seated gate valve uses a flexible sealing surface on the wedge to provide dependable shutoff against the valve seat.
What does NRS mean?
NRS means non-rising stem. The stem remains within the valve assembly instead of extending upward as the valve opens.
How is the valve operated?
The supplied product information identifies a standard 2" operating nut for below-grade valve operation.
What is the purpose of a restrained joint?
A restrained joint helps mechanically secure compatible piping connections and resist forces that could otherwise separate the joint.
Is this valve intended for underground use?
Yes. The supplied product information identifies underground water service as a primary application.
Is the valve intended for throttling?
Gate valves are generally intended for fully open or fully closed isolation service rather than routine flow throttling.
What should I verify before ordering?
Confirm valve size, restrained joint compatibility, pipe outside diameter and type, operating nut requirements, system pressure, installation depth, and media compatibility before ordering.
Important Ordering & Installation Notes
- This listing is for a Midland Ductile Iron Gate Valve with RT x RT restrained joint connections.
- Available sizes are identified from 2-1/2" through 8".
- Confirm the required nominal valve size before ordering.
- Verify compatibility between the restrained joint ends and the intended piping system.
- Confirm pipe type, dimensions, and restraint requirements before installation.
- The supplied product information identifies a standard 2" operating nut.
- Confirm valve box, extension stem, or operating access requirements for the installation depth.
- Verify system pressure, temperature, and media compatibility before placing the valve into service.
- Support and align connected piping correctly before completing the restrained joint assembly.
- Install all restrained joint components according to the applicable connection requirements.
- Gate valves should generally be operated fully open or fully closed rather than used for routine throttling.
- Maintain appropriate above-grade access for future valve operation and maintenance.
- Confirm corrosion protection and burial requirements for the specific installation.
- Install according to applicable utility standards, project specifications, and manufacturer recommendations.
