The main function of the pipeline is to cut off. It is easy to open and close, and the advantages are: small fluid resistance. It can be used in the case of two-way flow of the medium. There is no directionality.
The sealing surface is not easy to be eroded when fully opened. The structure length is short. It is not only suitable for small valves, but also suitable for large valves.

NORTECH is one of the leading China DIN3352 gate valve  Manufacturer & Supplier.

What's DIN3352 gate valve ?

DIN3352 gate valve , a design principle that is dominant in preference for use in distribution systems.

The DIN3352 gate valve contains a wedge fully encapsulated with EPDM rubber that is permanently bonded to the wedge and meets ASTM D249. The valve body, bonnet, and stuffing plate are coated with fusion bonded epoxy (FBE) ,beautiful looking and excellent protection. Optional configurations also include a Non-Rising Stem (NRS) or Outside Screw & Yoke (OS&Y). DIN3352 gate valve  also can be operated with a Spur or Bevel Gear,and electric actuator.

DIN3352 gate valve are very popular for industrial application.

Main features of NORTECH DIN3352 gate valve ?

The body is made of ductile iron by precision casting moulding,It was designed by 3D software,with finite element analysis for the structure.The safety coefficient is over 2.5.Smooth bottom channel is designed,to avoid accumulation of impurities and to ensure small flow resistance.

The stem is made of stainless steel by rolling. Integral type,avoiding the use of the brass half rings to reduce stem diameter. the smooth modified ladder type screw is extruded. Global mirror polish,it fits the O rings well, to ensure that the smooth rotation and small torque.

The grade 8.8 bolts connect the bonnet and the body, the bolts were covered by hot-melt wax which protects the bolts for corrosion. The gasket between the bonnet and body is made of EPDM. The valve cover is machined with a retaining groove,make sure that the rubber gasket won't be extruded out under high water pressure.

Environmental friendly manufacturing

The inside and outside surface of the valve is coated with sanitary epoxy powder by fusion bonded epoxy(FBE), the average thickness is above 250um. The adhesion of the coating is strong,it won't be destroyed under the impact force test of 3J. Internal parts can meet with the environmental protection requirements,and can be used for the potable water,food and pharmaceutical area directly.The electrostatic powder coating process can promise high adhesion force and strong corrosion resistance

The rubber parts are made of high quality EPDM or NBR, which is in accordance with the drinking water requirements,avoiding  the problem of the common rubber which is likely to breed microorganism.The products is not only approved by chinese national quality standards for drinking water related products,but also approved by WRAS in UK and ACS in France.The stem nut is forged and rolled from the national standard brass rod (low content of lead),and no pollution to water.

Easy installation and operation

We offer various kinds of interface such as flange connection,PVC pipe socket, uctile iron pipe socket,reducing etc.The special connection design can be customised as per the requests .

The valve can be completely closed and reach at o leakage with small torque. The actual operating torque is only 80% of diameter, and the gate valves can bear the MST of 3*DN N.M. The products passed the life test of 5000 times. For the valves of large diameter, we can offer the labour saving devices, to ensure that all the valves can be opened and closed by one person. The handwheel is strong, with accurate dimensions, it fits well with the valve stem, the shape is in accordance with human mechanics, to ensure easy operation

Easy maintenance

The seal ring can be replaced without cutting off the water,it's easier for the maintenance and reduce the maintenance time as much as possible.Very small friction between the brass bushing and the "O" type seal,it will ensure long life of the seal ring.The max. operating torque is under the control.
