Description
These premium PVCu foot valves with plain metric sockets are designed to maintain prime in suction lines while preventing backflow and protecting pumps. Manufactured from robust unplasticised PVC, they provide a secure, reliable solution wherever consistent one-way flow is essential.
Ideally suited to potable water systems, these foot valves offer excellent resistance to corrosion and abrasion, even in demanding environments. Available in a choice of metric sizes from 20mm to 63mm, they are a dependable choice for water treatment, irrigation, industrial process water and building services installations.
Product Features
- Constructed from durable PVCu (unplasticised PVC) for long service life in potable water applications.
- Plain metric socket ends for straightforward solvent-weld installation onto 20mm, 25mm, 32mm, 40mm, 50mm and 63mm pipework.
- Integrated non-return valve to maintain prime and prevent reverse flow in suction and intake lines.
- High resistance to corrosion, scaling and abrasion for consistent performance in demanding service conditions.
- Optimised flow design to minimise pressure loss while ensuring effective check action.
- Suitable for use with cold potable water and many compatible process fluids within recommended temperature and pressure limits.
- Lightweight construction for easy handling and installation compared with metal equivalents.
Key Features and Benefits
- Helps protect pumps and associated equipment by preventing backflow and loss of prime in suction lines.
- Non-corroding PVCu body delivers reliable performance in chlorinated and potable water systems, reducing maintenance requirements.
- Plain socket ends allow fast, secure solvent-weld joints, cutting installation time on site.
- Smooth internal surfaces reduce friction losses and the risk of debris build-up, helping to maintain system efficiency.
- Range of metric sizes from 20mm to 63mm enables easy integration into new or existing plastic pipework layouts.
- Resistant to many common chemicals used in water treatment, supporting long-term system integrity when correctly specified.

- Water treatment and filtration plants where consistent suction line priming is essential.
- Booster sets and pumping skids using PVCu metric pipework on the suction side.
Frequently Asked Questions
Can these PVCu foot valves be used in potable (drinking) water systems?
Yes, the valves are manufactured from PVCu suitable for use in correctly designed and installed potable water systems. Always ensure that the complete system, including all fittings and jointing materials, is specified and installed in line with relevant regulations for drinking water.
How are the plain metric sockets on these foot valves connected to the pipe?
The plain metric sockets are designed for solvent-weld jointing. The mating PVCu pipe ends should be cut square, cleaned and prepared, then bonded using a compatible solvent cement following the cement manufacturer’s instructions and applicable installation standards.
Which size foot valve should I choose for my installation?
Select the foot valve size to match the outside diameter of your PVCu pipework. For example, use a 32mm valve with 32mm pipe, a 50mm valve with 50mm pipe, and so on. Choosing the correct matching size ensures a secure solvent-weld joint and helps maintain the designed system flow rate.
