Total reliability and quality for a great shower, every time. That’s what Trevi technology gives you.
Solid Brass Body
All Trevi valves have a solid-cast brass body. Why brass? Because it’s durable and reliable. This, in addition to precision-engineered parts such as the casings for the ceramic disc cartridges, thermostat and non-return valves, means a Trevi shower never fails to deliver. Our commitment to quality is unrivalled.
Our thermostatic wax capsule cartridge is manufactured to the highest standards, with a solid brass outer and a shuttle that ensures precision temperature control. The shuttle regulates the mixture of hot and cold water in the mixing chamber of the valve. If either the hot or cold water supply fails, the shuttle closes the relevant port within 1.5 seconds, thereby preventing the risk of scalding. Pivoted on a unique, patented rubber membrane which allows it to move freely, even when limescale has hardened around the cartridge, the result is a market leading, maintenance-free thermostatic shower valve, making Trevi shower valves true “fit and forget” products.
The ceramic discs used in Trevi valves are the most efficient and reliable way of ensuring a consistent and precise water flow. What’s more, all our products are drip-free and resistant to the build up of limescale which affects performance. The smooth, easy to turn operation of ceramic disc cartridges adds to the quality feel that is synonymous with Trevi.
Non Return Valves
Non return valves (NRVs) conventionally prevent water crossing over from the cold to hot water supply, which can cause the hot water tank to flood. NRVs also prevent water from being drawn up from the handset and back into the mains supply which leads to contamination. Our TT collection NRVs are reversible, so if the hot and cold supply pipes have been plumbed-in the wrong way, you simply reverse the NRVs. That means no need to re-plumb, therefore saving both time and money.
Twin Sealing System
Sealing System One – This is a conventional water-proof foam type seal which is incorporated into the face plate sealing gasket. When the face plate is screwed on to the valve the seal is compressed and forms a flexible seal over uneven surfaces.
Sealing System Two – This seal is a flexible rubber gasket, incorporating fins designed to fit into the tilting trim surrounding the valve in the wall. The purpose of this gasket is to provide an additional seal against water penetration.
