PRV9i – the 9 bar interchangeable pressure regulating valve


PRV9i is a 9 bar, interchangeable pressure regulating valve for defence, construction, oil & gas and petrochemical applications.


Walter Frank designed and launched the PRV9i range in 2008 in response to the need for a genuine 2.5” Nominal Bore pressure regulating valve. PRV9i offers the end user great flexibility from both a maintenance and operational perspective due its interchangeable cartridge system. This means the ‘through life’ cost of PRV9i is less expensive than competing products because servicing is quicker and easier with less down time on the system. PRV9i has the ability to regulate pressure from 3.5 to 9 bar and is available in various configurations. Since its inception the range has been specified for use in prestigious projects such as Heathrow Airport (UK), the Wheatstone offshore project (Australia), the ZADCO project (UAE), and the Crossrail London Underground project (UK).


UK Made & Quality Assured

 

UK h233pxPRV9i valves are manufactured and assembled in our production facility in the United Kingdom. Quality is assured by our numerous approvals and certifications.

 

Design, casting, machining and assembly plus full flow testing and calibration are all performed in-house. Full certification and testing is available as required. PRV9i is unique in exceeding the requirements of British fire-fighting Standard BS9990 in terms of interchangeability and performance. PRV9i is for large scale infrastructure projects where trust and reliability are fundamentals of supply for such safety critical environments.

 

   
 

A Valve for Home and International Projects

 

PRV9i is at the forefront of pressure regulating equipment in the global fire-fighting industry. Compliance to national and international standards makes PRV9i the valve of choice for home and international projects.

 

PRV9i can be certified by independent bodies such as Lloyds, and Underwriters Laboratory (UL). PRV9i is therefore the prominent choice for fire-protection for petro-chemical and demanding infrastructure environments where such approvals are automatically requested. PRV9i has already been supplied for many high-profile building projects including Bishopgate Tower (“The Pinnacle”) in London.

 

As a complete and flexible solution to pressure regulation in offshore environments, PRV9i has been specified for projects involving the outfitting, refurbishment and maintenance of offshore platforms. In recent times, Walter Frank has supplied over 1000 PRV9i valves for the Wheatstone LNG onshore project in Onslow in Western Australia. This project involved the design and complete supply of the firewater hydrant station including all coded fabrication work. Other projects of note for PRV9i include the design and supply for the ZADCO project (UAE) which included the design and complete supply of the permanently charged wet barrel pillars, as well as the Crossrail project (UK) which utilised a bespoke design for hydrant assemblies for the tunnel sections to run across London. These projects demonstrate our ability to supply complete solution packages to our customers for large infrastructure and demanding projects.
