4"-12" Resilient Wedge NRS Gate Valves with ALPHA™ Restrained Joint Ends

The AMERICAN Series 2500 Ductile Iron Resilient Wedge Gate Valve is available with ALPHA ends in sizes 4” -12”. The valve is designed for use in drinking water, sewage and fire protection systems as well as irrigation and backflow control systems. Its unique design offers the following benefits when compared to a valve configured with mechanical joint ends:

Material Flexibility

The ALPHA inlet is compatible with several pipe materials, including ductile iron, cast iron, HDPE and PVC pipe. ALPHA's unique design does not requre the use of a stiffener in HDPE pipe, DR17 or less. This means it will work with just about any pipe material on the job.

Significantly Reduces Installation Times

Compared to mechanical joint, which uses up to eight T-head and eight wedge bolts on each end, the ALPHA restrained joint uses only one top-mounted stainless steel bolt. This makes the valve or hydrant with ALPHA restrained joint ends easier to install, which saves time and money.


The ALPHA restrained joint is much more accessible than other end connections. Mechanical joints, which require bolts on the bottom of the valve, can be harder to install. ALPHA can be quickly and easily installed by one person in a fraction of the time it takes to install a mechanical joint valve. In some instances, the mechanical joint may require more than one person install.


Unlike the mechanical joint, the ALPHA restrained joint comes with the restraint accessories attached. ALPHA  has a unique one-piece End Ring to ensure an even loading of the gasket and employs a Ductile Iron Gripper style restraint to provide an even distribution of thrust restraint.

Easier to Install

The ALPHA restrained joint also works with the pressure to achieve restraint by using pressure-energized gasket that works with the pressure to seal. This reduces the amount of torque needed to achieve a solid connection to 45 ft-lbs or less.
