25mm Large Large Air Release Check Valve for ASD Systems
£26.65 (inc VAT: £31.98)
Summary
The Plimat RED30P025I is a large air release check valve designed specifically for use in 25mm aspirating smoke detection (ASD) pipework systems. This essential accessory prevents air from travelling backwards through the pipe network during cleaning and maintenance operations, protecting the integrity of the ASD installation and ensuring system reliability is maintained throughout its service life.
Manufactured by Plimat, a specialist producer of high-quality plastic pressure pipe systems with a long-established reputation in the fire detection industry, the RED30P0250 is engineered for professional installations where 25mm imperial-sized pipework is employed. The valve is an important component for any ASD system that requires periodic pipe cleaning, providing a straightforward and effective solution for controlling airflow direction within the sampling pipe network.
The RED30P025I is compatible with all major brands of low-pressure aspirating smoke detection systems, including VESDA, FAAST and ICAM. It is designed to work seamlessly within 25mm ASD pipe networks, making it an ideal companion component to the wider range of Plimat ASD pipe and fittings available in the same metric sizing.

FAQ
What is the Plimat RED30P025I used for?
The RED30P025I is a large air release check valve designed for 25mm ASD aspirating smoke detection pipework. Its primary purpose is to prevent air from travelling backwards through the pipe network when the system is being cleaned, protecting the ASD detector and maintaining system integrity.
What pipe size is the RED30P025I compatible with?
The RED30P025I is designed for use with 25mm aspirating smoke detection pipework. This is an metric-sized pipe, also referred to as 25mm, commonly used in ASD installations alongside VESDA, FAAST, ICAM and other major aspirating smoke detection systems.
What is the difference between the RED30P0250 and the RED30P020I?
Both are Plimat air release check valves for ASD systems, but they are designed for different pipe sizes. The RED30P020I is the compact version designed for 25mm (metric) ASD pipework, whilst the RED30P0250 is the larger version for 27mm (3/4″) imperial-sized pipework. Selecting the correct valve depends on which pipe size has been used in your ASD installation.
Why is a check valve needed in an ASD system?
During routine maintenance and pipe cleaning of an aspirating smoke detection system, air can be forced backwards through the sampling pipe network. This reverse airflow can potentially damage or contaminate the ASD detector. Fitting a check valve such as the RED30P025I prevents reverse airflow, ensuring that cleaning procedures can be carried out safely without risk to the detection equipment.
Is the RED30P025I compatible with all ASD systems?
The RED30P025I is designed for use with all major brands of low-pressure aspirating smoke detection systems that use 25mm pipework, including VESDA, FAAST and ICAM. If you are unsure whether this valve is suitable for your specific ASD installation, please consult your system manufacturer’s documentation or contact Huvo for technical guidance.
Can the RED30P025I be used with both red and white 25mm ASD pipe?
Yes. The RED30P025I is compatible with both red and white ABS 25mm aspirating pipe. The colour of the pipe does not affect the mechanical compatibility of the valve — both pipe colours share the same 25mm metirc dimensions and are used interchangeably within ASD installations.
