Hover Over to Zoom In
Overview
533 pressure reducing valves have a specially shaped diaphragm to give accurate pressure regulation in response to changes in downstream pressure
The larger outlet chamber creates a low exit velocity which is effective in reducing water noise
The control stem housing of the cartridge is made from a plastic material with a low co-efficient of adhesion, which reduces the probability of scale deposits forming, the main cause of pressure reducing valve malfunction
The cartridge and strainer screen are easily removed for periodic cleaning and maintenance
Valves for use with copper tube have compression ends complying with BS EN 1254-2
Take control of your room temperature and reduce energy bills with the Inta i-Therm 108TWINA 10/8mm Angled TRV Pack. Compatible with microbore central heating pipes, it includes an angled thermostatic head and lockshield valve. With a liquid-filled sensor, it maintains accurate temperatures from 0°C to 30°C. Its bi-directional body allows versatile installation, and the anti-chatter cartridge prevents water-hammer noise. The sleek, minimal design prevents dirt traps, ensuring durable, reliable performance.
