Features & Benefits
Design & Performance
With a strength in design and excellent materials for the containment and isolation of hazardous liquids and gases, the series 8800/1 & 8900/1 ranges have built an enviable reputation for long service life and excellent performance.
Containment of Dangerous Emissions
All valves are fitted with a UNS N10276 bellows seal guaranteed for the life of the valve. Valves are also designed with back up secondary pure PTFE packing glands and seals as standard.
Repeatable tight closure and isolation
For metal to metal seated valves the disc is harder than the seat minimising disc damage during operation ensuring long life for the seating surfaces.
Open Bellows Design
Our design of open bellows and bolted top assembly gives easy access to inspect the bellows assembly area. The open design ensures that any corrosion products in the fluid do not get trapped around the bellows causing damage and early failure. The bellows are guaranteed for the life of the valve.
Body Integrity and wall thickness
Small valve bodies and all sizes of bonnets are forgings. Cast body integrity is monitored by 100% x-ray inspection, while wall thickness is in accordance with Euro Chlor specifications for use on liquid chlorine services. Hunt & Mitton Valve Company is the only manufacturer of Euro Chlor approved valves to offer 100% radiography of all castings for chlorine service.
HandWheel Easy Operation
We have ensured that the manual valves are easy to operate using cast three or four spoke large diameter wheels and the use of needle roller thrust bearings fitted on sizes 1 1/2” (DN40) andabove Class 300 to ensure easy operation and rotation when opening and closing the valve.
Xylan® coated
All studs and nuts are coated with Whitford Xylan® anti corrosion, self lubricating compound.
