Valve Configuration
Mechanical Joint Inlet
One MJ end connects to compatible waterworks pipe using the appropriate gland, gasket, bolts, and related joint components.
Resilient Wedge Body
The internal resilient wedge moves through the ductile iron valve body to provide dependable full-open or full-closed isolation.
Mechanical Joint Outlet
The opposite MJ connection continues the underground water piping system using compatible mechanical joint components.
Construction Details
The Midland AWWA C515 gate valve is manufactured with a heavy-duty ductile iron body and bonnet for strength and durability in demanding waterworks service.
A stainless steel non-rising stem provides smooth valve operation and corrosion resistance while remaining protected within the valve assembly.
The resilient encapsulated wedge helps provide positive sealing while minimizing operating torque, and MJ x MJ end connections simplify installation into compatible municipal water distribution piping.
Why Choose an AWWA C515 Gate Valve?
Waterworks Performance
- Manufactured to AWWA C515 requirements
- Designed for municipal water service
- 300 PSI working pressure rating
- Resilient wedge sealing
- Ductile iron construction
Underground Installation
- Mechanical joint connections on both ends
- Non-rising stem configuration
- Compact operating profile
- Suitable for buried water mains
- Multiple large-diameter sizes available
Non-Rising Stem Design
Compact Operation
The non-rising stem remains within the valve assembly during opening and closing, reducing the amount of vertical clearance required.
Below-Grade Service
The compact NRS configuration is well suited for buried installations where valve operation is performed through a valve box, extension, or compatible operating arrangement.
Mechanical Joint Connections
MJ Inlet
The inlet uses a mechanical joint connection with compatible gland, gasket, bolts, and piping components.
MJ Outlet
The outlet uses the same mechanical joint connection style for straightforward integration into compatible waterworks piping.
Typical Applications
Municipal Water Systems
- Water distribution mains
- Municipal utility piping
- Transmission systems
- Underground isolation points
- Potable water infrastructure
Commercial & Utility Systems
- Site water mains
- Commercial water distribution
- Underground service piping
- Utility infrastructure
- Large-diameter water systems
Resilient Seated vs. Metal Seated Gate Valve
Resilient Seated Gate Valve
A resilient seated gate valve uses an elastomer-covered wedge to provide dependable sealing and reduced leakage in compatible water service.
Metal Seated Gate Valve
A traditional metal seated design relies on metal-to-metal seating surfaces and may be selected for different service conditions or project requirements.
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 MJ x MJ mean?
MJ x MJ indicates mechanical joint connections on both ends of the valve.
What standard does this valve meet?
The supplied product information identifies the valve as manufactured to AWWA C515 requirements.
What is the pressure rating?
The supplied product information lists a 300 PSI working pressure rating.
What sizes are available?
The supplied product information lists 3", 4", 6", 10", 12", 14", 16", and 18" nominal sizes.
What material is the valve body made from?
The supplied product information identifies heavy-duty ductile iron body and bonnet construction.
What material is the stem?
The supplied product information identifies a stainless steel stem.
What does NRS mean?
NRS means non-rising stem. The stem remains within the valve assembly rather than extending upward as the valve opens.
What is a resilient wedge?
A resilient wedge uses a flexible sealing surface designed to provide dependable shutoff against the valve seat.
Is this valve suitable for underground installation?
Yes. The supplied product information identifies underground water distribution systems as an intended application.
Is this valve intended for potable water service?
The supplied product information identifies potable water and municipal water distribution as intended applications.
Is this 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, mechanical joint compatibility, pipe dimensions, pressure requirements, installation depth, operating arrangement, and project specifications before ordering.
Important Ordering & Installation Notes
- This listing is for a Midland AWWA C515 Resilient Seated Gate Valve with MJ x MJ connections and a non-rising stem.
- Available sizes are 3", 4", 6", 10", 12", 14", 16", and 18".
- The supplied product information lists a 300 PSI working pressure rating.
- Confirm the required nominal valve size before ordering.
- Verify mechanical joint compatibility with the intended piping system.
