Valves

Designed for dependable flow control in demanding hot and cold water installations, our range of HTA CPVC valves provides a robust, lightweight and corrosion-free alternative to traditional metal valves. Manufactured from high-performance chlorinated polyvinyl chloride (CPVC), these valves are purpose-built for potable water systems where reliability, safety and long service life are essential.

Suitable for use across commercial, industrial and public sector applications, HTA valves are fully WRAS approved, making them ideal for drinking water distribution in environments such as hospitals, schools, hotels and large residential developments. Their smooth internal bore helps maintain efficient flow, supporting pump performance while reducing pressure losses, limescale formation and biofilm build-up.

• Hot and cold water compatible - Designed to operate across a wide temperature range, from 5°C up to 90°C (application dependent)
• High pressure performance - Engineered for pressurised systems, with selected valves rated up to 25 bar
• WRAS approved - Certified for the safe conveyance of potable (drinking) water
• Corrosion-free construction - CPVC will not rust, scale or degrade, even in aggressive water conditions
• Lightweight and easy to install - Reduces handling effort and installation time compared to metal alternatives
• No hot works required - Solvent weld system compatibility improves on-site safety and efficiency

This category includes a selection of purpose-designed isolation valves to suit different installation requirements, including:

Double Union (DU) Ball Valves

Ideal where regular maintenance or future valve replacement may be required. The double union design allows the valve to be removed without disturbing the surrounding pipework, while integrated anchoring points help support the valve body and protect the system from mechanical stress.

Flanged Ball Valves

Designed for secure installation in larger or higher-load systems. Flanged connections provide excellent stability, while integrated anchoring systems ensure safe mounting and long-term pipework integrity.

Manufactured as part of the HTA hot and cold water system by Durapipe, an Aliaxis brand, these valves are fully compatible with HTA pipes and fittings. Using a matched system ensures consistent performance, simplifies specification, and delivers a cost-effective alternative to copper and other metal pipework solutions.

Whether you’re isolating sections of a potable water system, managing flow in high-pressure installations, or specifying a corrosion-resistant solution for long-term reliability, HTA CPVC valves offer a proven, standards-compliant choice for modern hot and cold water distribution systems.
