APPROVAL<\/h4>\n
National Hygiene Institute Warsaw.<\/p>\n
TECHNICAL DATA<\/h4>\n
Threaded connection acc. to PN-EN 228-1.
\nRequirements and tests according to PN-EN 1074 \u2013 1 and 2<\/p>\n
CONSTRUCTIONAL FEATURES<\/h4>\n\n- Drilling under pressure using a drilling machine.<\/li>\n
- Integrated with a gate valve cat.-no 2655, 2665, 2675. 2655, 2665,2675.<\/li>\n
- Outlets with threads G 1\u2033, G 1 1\/4\u2033, G 1 1\/2\u2033 and G 2\u2033.<\/li>\n
- Can be assembled on PVC and PE pipes.<\/li>\n
- Full, smooth, even and cavity-free passage.<\/li>\n
- The valve stem sealing may be replaced under full pressure in any position of the wedge.<\/li>\n
- A stainless steel stem with cold rolled thread, without notches in the sealing zone, which makes it possible to work with o-rings placed in the screw.<\/li>\n
- Triple sealing system of the stem: top seal, set of 5 o-rings (4 o-rings inside and outside the screw), bottom seal, lip seal.<\/li>\n
- Gate body, bonnet and wedge made of ductile cast iron EN-GJS 500-7 grade. <\/li>\n
