Adoptive standards:

1. Face to face is according to DIN3202
2. Flange drilling is according to EN1092-2

Test
Working pressure: PN16
Test pressure Shell: 2.4Mpa
Seat: 17.6Mpa

Components Material:
1.Body: ductile iron GGG40
2.Bonnet: ductile iron GGG40
3.Disc: dutile iron+EPDM
4.Stem: SS410,2Cr13,brass

Features:

1.General valve often in the water flushing pipe after that due to foreign objects such as concrete blocks, iron and other debris deposition in the valve at the end of the groove,
likely to cause can not be closed tightly and the formation of water leakage, elastic seat sealing gate valve at the bottom of the pipe with the same flat design, not easy to cause debris deposition, so that smooth flow of fluid.
2.Casting valve
Body using precision casting, precise geometric size makes the body can not be processed at any time to ensure that the valve seal.
3.Valve plate package
Valve plate with high quality rubber were both inside and outside the overall package glue, Europe's leading rubber vulcanization technology makes vulcanization after the valve plate to ensure accurate geometry and rubber and ductile cast iron valve plate then solid, not easy to fall off and elastic memory preferred.
4."O" type ring sealing ring
Due to the stem and the valve cover with three "O" ring seal design, can reduce the friction resistance of the switch, greatly reduce the leakage phenomenon and can not stop the flow of media in the pipeline to replace the sealing ring.
5.Help to drink
Due to the internal body with non-toxic epoxy resin coating, the inner and outer surface of the valve plate is completely covered with rubber and does not appear the phenomenon of molten iron or corrosion, can be used for drinking.
6.Labour saving device
DN450-600mm, otherwise install laborsaving devices, required torque is about 1 / 2 of the normal, only a small handwheel, under pressure, can be operated fully open or fully closed, the labor-saving device in each action a, the valve is fully open to restore the function of labor saving.

Application:

1.Pipelines and manifolds ;
2.Drilling and chemical treatment;
3.Oil, gas and water pipelines;
4.Sour gas and crude oil;
5.Abrasive and corrosive mud, cements, slurries and water flood.
