Manual valves in PVC Astore

The Astore line of valves and fittings in PVC is recommended for irrigation and agriculture, for swimming pools but also for shut-off in water distribution and treatment plants.

The Astore brand offers ball and butterfly valves and supplements the offer with spring-loaded check valves and clapet valves.

The range of PVC-U fittings completes the Astore line with fittings for glueing, threaded and transit.

New PVC fittings Astore

The new Aliaxis range of Astore-branded PVC fittings offers a harmonized range, with a more functional design and high quality level.

🔸 Clear and complete markings on the product: Astore brand, quality and approval marks, dimensional information and material specifications

🔸 New design: aesthetics and quality

🔸 Conical threads according to ISO 7

The range of PVC fittings includes figures for gluing, threaded and through and is ideal for irrigation systems and various applications in agriculture, for conveying swimming pool water but also for interception in distribution and water treatment systems.

Compression joints and saddle clamps Astore

Astore branded PP compression joints are particularly suitable for connecting PE pipes for water transport, used both for irrigation applications and on drinking water systems or to be made potable.

The Astore mechanical saddle clamps are the ideal technical solution for user derivations for both irrigation and aqueduct networks.
