DMZ73H manual concealed stem knife type gate valve

DMZ73XManual concealed stem knife gate valve slurry valve

DMZ73X-10CLarge caliber manual concealed stem knife gate valveDMZ73X-10PLarge diameter knife gate valveSuitable for use in power plants, mines, papermaking, metallurgy, chemical engineering, sewage treatment, and other industries for opening, closing, or regulating flow in pipelines containing abrasive and corrosive slurries and particles. Applicable nominal pressure0.6MPa～1.6MPaAdapt to temperature-40℃～1000℃The structural form can be divided into two types: hard seal and soft seal. The sealing performance is good, and the valve body is made of carbon steel or stainless steel material, with high pressure resistance and good wear resistance of the sealing surface. It is easy to install, has less dust sticking and ash deposition, and has a long service life.

2、 Product features:

DMZ73X-10CLarge caliber manual concealed stem knife gate valveDMZ73X-10PThe large-diameter knife gate valve features a fully circular DC channel design that is free from slag and blockage. The bottom of the valve plate is processed into a blade shape, which has a cutting function for fly ash, ash residue, pulp, etc., and also has good opening and closing effects. The valve plate can achieve good sealing effect after precision grinding and polishing treatment. Compact design, small space occupation, light weight, affordable price, easy installation, complete wear-resistant and anti blocking measures, easy maintenance, convenient use and long service life, and can freely choose the driving device.

2The valve body and packing culvert are both precision cast, with the valve body being cast as a whole, and the material can be selected according to user needsWCB、304、316The316L、2520Wait, the packing material uses graphite packingPTFEMade of polytetrafluoroethylene material, corrosion-resistant, wear-resistant, and slag free.

3The valve plate has3A support point to ensure good self centering of the valve plate. When the valve is in the closed state and subjected to back pressure, the valve plate does not shift.

4The drive mode of knife gate valve can be configured with handwheel, electro-hydraulic, sprocket, bevel gear, pneumatic, hydraulic and electric.

5The connection forms of knife gate valves include clamp type and flange ear type, and the seals include metal to metal hard seal, metal to rubber, polyurethane, and polytetrafluoroethylene soft seal.

6Applicable media: fly ash, gold ore powder, tailings, pulp, wood pulp, fiber, dust, rainwater, chemical treatment wastewater, sedimentation tank, mineral sand, slag, coal slurry, asphalt, silo outlet, fruits, grains, cement slurry, slaughterhouse wastewater, etc.

7Scope of application:
