Features & Benefits
Design & Performance
With a strength in design in accordance with GEST 90/150 and excellent materials for the containment and isolation of hazardous liquids and gases, the Fig 6800/1 range has built an enviable reputation for long service life and excellent performance.
Containment of Dangerous Emissions
All valves are fitted with a pure PTFE packing twice the length of valve travel and protected by a gland scraper bush 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.
Packed Gland Design
Our design of packed gland combined with a deep packing chamber of more than twice the travel ensures zero leakage.
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.
Hand Wheel 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 1 1/2” (DN40) and above Class 300 rating, 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.
