Alpha Boiler Pressure Relief Safety Valve (1.028643)
The Alpha Boiler Pressure Relief Safety Valve (Part No: 1.028643) is a critical mechanical safety component engineered specifically for the Alpha Intec condensing combi and system boiler ranges. This spring-loaded safety valve is calibrated to act as the primary defense mechanism for the boiler's hydraulic network. When central heating system pressure spikes due to overheating, a failing expansion vessel, or overfilling, the valve's calibrated internal spring mechanically compresses once system pressure reaches a maximum safety threshold of 3.0 bar. This opens a dedicated discharge pathway, safely venting excess primary water out through the external blow-off pipework to protect the main heat exchanger and hydraulic manifold from structural over-pressurization damage.
-
Over-Pressurization Defense: Automatically trips open at a precise 3-bar limit to discharge localized fluid volume, preventing catastrophic pressure fractures across the composite hydro-block assemblies and pipe joints.
-
Heavy-Duty Spring Calibration: Constructed with an industrial-grade internal compression spring that maintains exact mechanical resistance, avoiding premature weeping or pressure loss under normal running states.
-
Thermal-Shock Resilience: Equipped with high-grade elastomeric internal seats designed to handle intense, boiling water temperature spikes without melting, ensuring a tight, positive reset seal once pressure normalizes.
-
Threaded Seating Layout: Built to the manufacturer's exact dimensional specifications for a direct thread-in fit, providing a secure, leak-free connection inside the boiler's primary water return sector.

We have a 14-day return policy, which means you have 14 days after receiving your item to request a return.
To be eligible for a return, your item must be in the same condition that you received it, unworn or unused, with tags, and in its original packaging. You’ll also need the receipt or proof of purchase.This may result in some fee cuts.
The shipping fee for the returned products is our customers responsibility. Also, the shipping fee for the first shipment will be calculated and taken from the buyer. This value comes from the shipping value it cost to send your initial order.
To start a return, you can contact us at support@aspares.co.uk If your return is accepted, we’ll send you a return shipping label, as well as instructions on how and where to send your package. Items sent back to us without first requesting a return will not be accepted.
You can always contact us for any return question at support@aspares.co.uk
Damages and issues
Please inspect your order upon reception and contact us immediately if the item is defective, damaged or if you receive the wrong item, so that we can evaluate the issue and make it right.
Exceptions / non-returnable items
Certain types of items cannot be returned, like perishable goods (such as food, flowers, or plants), custom products (such as special orders or personalised items), and personal care goods (such as beauty products). We also do not accept returns for hazardous materials, flammable liquids, or gases. Please get in touch if you have questions or concerns about your specific item.
Unfortunately, we cannot accept returns on sale items or gift cards.
Exchanges
The fastest way to ensure you get what you want is to return the item you have, and once the return is accepted, make a separate purchase for the new item.
