Self-drilling saddle valve Jafar for PE and PVC pipes DN110×2, model 3250-110G50-2E16

Self-drilling saddle valve Jafar for PE and PVC pipes DN110×2, model 3250-110G50-2E16 is a clamp-on branch valve engineered for creating safe and reliable outlets on plastic mains without the need to cut or replace the primary pipeline. The unit combines a contoured saddle body that fits DN110 pipelines with a built-in drilling mechanism, enabling a single-step installation to form service taps, drainage points or inspection outlets for utility, irrigation and drainage systems.

Advantages

The saddle valve offers a compact, integrated solution that reduces installation time by eliminating separate drilling and tapping operations. Its clamp design provides a secure mechanical connection to PE and PVC pipes with nominal diameter DN110 and wall factor x2, while the self-drilling feature ensures accurate penetration and consistent sealing. Constructed from materials compatible with plastic mains, the valve minimizes risk of damage to the host pipe and simplifies future maintenance or replacement.

Suitable for

• Creating service taps on PE and PVC distribution mains DN110×2
• Installing drainage or inspection outlets on irrigation and stormwater pipelines
• Adding branch connections for utilities and outdoor water systems
• Temporary or permanent tapping where trenchless attachment is preferred

Key specifications

• Compatibility: designed for polyethylene (PE) and polyvinyl chloride (PVC) pipelines with nominal diameter DN110 and wall factor x2
• Design: clamp-on saddle with integrated self-drilling mechanism
• Function: enables branch connection without cutting the main pipeline
• Application areas: utility distribution, irrigation, drainage and inspection outlets
• Operational benefit: single-step installation for tapping and sealing

How to use

Position the saddle on the clean, dry section of the DN110 pipe at the chosen outlet location, ensuring the contoured underside matches the pipe curvature. Secure the clamp evenly around the pipeline using the provided fasteners and tighten to the manufacturer's recommended torque so the sealing surface contacts the pipe uniformly. Engage the integrated drilling mechanism and advance until the valve penetrates the pipe wall; retract the drill component if required and complete the valve assembly according to the installation sequence. Verify the seal and test the branch connection under low pressure before placing into regular service.

Usage recommendations

Inspect the host pipe for surface damage or significant deformation before installation. Use appropriate personal protective equipment and follow local regulations for working on live or pressurised mains. For long-term connections, ensure the selected outlet orientation and downstream fittings match system pressure and flow requirements; periodic checks of fastener tension and seal condition are advised.
