HAZARDOUS CHEMICAL VALVES (HCV)
Manual Bellows Seal Isolation Valves-Series 8800/1 Straight pattern -Series 8900/O1 Angle Pattern
Design & Performance
With a strength in design and excellent materials for the containment and isolation of hazardous liquids and gases, the series 8800/01 & 8900 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 guaran-
teed for the life of the valve. Valves are also designed with
back up secondary pure PTFE packing glands and seals as
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. Polymer ring soft seat plugs are also available.
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 Eurochlor specifications
for use on liquid chlorine services.
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 and ball bearings are fitted on sizes 1
1/2″ (DN40) and above to ensure easy operation and rotation
when opening and closing the valve.
All studs and nuts are coated with Whitford Xylan anti corro-
sion, self lubricating compound .
