SHUANGLIN VALVE | PPR Double Union Ball Valve, DE20–DE110

When an entire piping run is built from PPR pipe, introducing a shut-off point shouldn't mean switching materials or connection methods. SHUANGLIN VALVE's PPR double union ball valve keeps the system consistent — both ports are PPR socket ends designed for heat fusion, so the valve welds directly into the pipeline just like any other PPR fitting.

Built to Match Your PPR System

Because both connections use the same heat fusion method as the rest of a PPR network, this valve integrates without introducing a different jointing technique, a different expansion behavior, or a potential weak point where dissimilar materials meet. The internal ball and stem are brass, chosen for durability and smooth quarter-turn operation, while the PPR body and socket ends bond permanently to the adjoining pipe during installation — creating a joint as strong as the pipe itself once fused.

Union Design for Serviceability

Despite the permanent heat-fused connection to the pipeline, the valve itself uses a union-style middle joint, so it can be unscrewed and removed from the line for maintenance, ball replacement, or system modification without needing to cut out and re-weld a section of pipe. This is a meaningful advantage over a valve that would otherwise need to be sawn out if it ever required service.

SHUANGLIN VALVE produces this double union ball valve across the DE20 to DE110 size range, with a blue handle marked for PP-R systems, and internal materials rated for both hot and cold water service.

Frequently Asked Questions

How is this valve connected to the pipe — glued, threaded, or welded? Both ends use heat fusion (socket welding), the same jointing method used throughout a standard PPR pipe system. The socket is heated along with the pipe end and pressed together to form a permanent, homogeneous joint.

Can the valve be removed later if it needs servicing? Yes. Although the connection to the pipeline is permanent once fused, the valve body itself uses a union nut in the middle, allowing it to be unscrewed and separated from the fused end sections for maintenance or replacement.

What sizes are available? SHUANGLIN VALVE produces this PPR double union ball valve from DE20 to DE110. Contact us with your pipe diameter for a tailored quotation.

Is this valve suitable for hot water systems? Yes, the valve is rated for both hot and cold water service, consistent with standard PPR piping system temperature ratings.
