DIN 3352 F4 Resilient Seated Flanged Gate Valves

Product introduction
The valves disc is rubber-packed to get excellent sealing effect by the rubber's resilient deformation.
Non-rising resilient seated gate valves solve the problem in general gate valves such as leakage, rusting etc. and saves installation space. It is used widely in tap water industry, sewage treatment, shipping construction,petroleum, chemicals, food, pharmacy, textile, electric power, metallurgy and energy system's pipeline to adjust and shut off fluids.
 
Product Features

 Product Advantages
1.The body is ductile iron,high level than national stanard.Tensile strength is 450Mpa，elongation is large than 10%，can not be broken easily when transport.
2. Both inner and out part is epoxy coating, the thickness is 250μm minimum,can prevent rust well,can be used in  sewage system. 
3.The wedge is coated with EPDM, the EPDM proportion can reach 50%，steable and good resilient.
4. 3 O rings are used on 2Cr13 stem,can reduce friction，prevent leakage,can change sealing ring with stop water.
5.The stem use brass, operate easily,prevent block.
6.Every link, from workblank to the finished product packaging will be inspected strickly.
