Valve Sizing Tool


We have supplied thermostatic control products into health and care facilities since our inception in 1909, and it still forms our core market today. The first order in our first record book describes an automatic steam control valve for Glasgow's Ruchill Hospital, a treatment centre for infectious diseases from 1900 until its closure in 1998.

In the early 1920s, after establishing the local hospitals, fever-, poor-, work- and bath-houses as our main customer base, we responded to their needs with the invention and development of the hot water blender - the precursor to today's thermostatic mixing valve.

In 1976, Legionella, a waterborne pathogen, was identified, which forced a regime change for water distribution in health and other public buildings. This led to the development of point-of-use thermostatic mixing valves that are now a regulatory requirement in healthcare.

Continuous Innovation

Extending the application of our thermostatic technology in the early 1980s led us to develop our first healthcare shower valve and this is now incorporated into a range of pre-plumbed shower panels with various shower head options and standard, lever or ligature resistant controls to cater for varying user needs and niche applications.

The Optitherm thermostatic clinical tap, which won a coveted Building Better Healthcare architectural award in 2008, combines our highest specification DN15 thermostatic mixing valve, our Horne 15 4th Connection, with a dual function (warm water and cold water) tap.  

In addition to providing safe and comfortable warm water for clinical and surgical hand decontamination, the Optitherm has also been designed to assist with water system management and make cleaning and maintenance easy.

In the last few years, the tragic deaths of neonates in a Belfast Hospital in December 2011, has brought opportunistic pathogens such as (multi drug resistant) Pseudomonas Aeruginosa and its retrograde contamination of healthcare water systems into focus. To mitigate the risk of the healthcare water system becoming a reservoir of potential infection by retrograde contaminants, we developed our In-Line Thermal Disinfection Unit, ILTDU, which is patented worldwide.

Assisting Operational Longevity

Innovative, accurate, reliable, safe, easy to use, easy to clean and straightforward maintenance are paramount concerns for all our healthcare product designs.

The healthcare environment is a demanding one and, as such, reliability, simplicity and durability are essential elements for an extended operational life.

In addition, we can assist customers to maximise product lifespan through low-cost spare parts and via special maintenance training resources: face-to-face seminars and online videos.
