Materials
• Refer to page 2
Standard design
• Semi--lug type body (Type 2) with aligment holes allowing
downstream pipe dismantling under PS or dead--end service
• Extended neck allowing insulation.
• Thermally insulating device for easier fixation of thermal
insulating jacket onto base skirt.
• Elastomer liner: an extra volume of rubber, located at the shaft
passage, provides, by compression between the valve
body and the disc edge, a perfect leak--tightness at the shaft
passages.
• Spherical machined disc ensures perfect upstream/
downstream sealing: zero leakage visible to the naked eye
• Tightness towards the exterior, downstream/upstream
tightness and hydraulic testing in accordance with:
EN 12266--1/leak level A, ISO 5208 category A.
ACS and DVGW approved
