MDPE Valve 40mm is a compression-fitting valve for 40mm MDPE pipe, built for tradespeople installing water supply and irrigation networks. It provides reliable flow control with leak-free joints when installed correctly, in a compact, durable MDPE assembly.
Key specifications
- Pressure rating: PN10, up to 10 bar (approximately 1 MPa or 145 psi).
- Material: MDPE body offering corrosion resistance to chemicals commonly found in water and irrigation systems.
- Joint type: compression connection designed to form leak-free joints when installed per guidance.
- Durability: resistant to weather exposure, temperature variation and mechanical stress.
- Applications: suitable for water supply, irrigation, rainwater harvesting and light industrial piping.
- Installation: no specialist equipment required for a straightforward compression-fit on 40mm MDPE pipe.
Use cases and benefits
- Ideal for 40mm MDPE pipe runs in domestic mains, garden irrigation circuits, and external water lines.
- MDPE’s chemical resistance helps extend service life when exposed to typical irrigation and fertiliser components.
- Leak-free joints reduce maintenance needs and protect againstwater loss in outdoor or exposed environments.
Installation tips
- Cut the pipe square, deburr and clean the end before assembly.
- Slide the compression nut and olive onto the pipe, insert fully into the valve, then tighten the nut until a seal is achieved according to manufacturer guidance.
- Pressurise the system and check for leaks at all joints; address any seepage promptly.
