Model：PZ73

Product overview:

1, the knife shaped sluice gate valve is made into two forms (dark rod DN100~1600mm, bright rod DN50~900mm) in accordance with the different caliber (dark rod and bright rod). The full circular DC channel is designed without slag storage and non blocking. The bottom of the knife plate is machined into a knife edge, which has the function of cutting off soft materials such as fiber, pulp and wood pulp, and has good opening and closing functions. A hard polytetrafluoroethylene scraper is installed on the upper end of the knife plate, which prevents dust, sand and other scraping substances from entering the packing box, and significantly improves the service life of the cutter plate. The best sealing effect can be obtained by using stainless steel, fine grinding and polishing.

2, the valve body, stuffing letter is precision casting, the valve body adopts the flange type overall casting, stainless steel, hard alloy material can be selected according to user needs 304, 316, 316L, 2520, WCB, 2Cr13, sealing ring with hard seal or PTFE reinforced polytetrafluoroethylene material, corrosion resistance, wear resistance, non dip slag.

3, the valve plate has a number of supporting points, so that the valve plate has a lot of self alignment. When the valve is closed and bears back pressure, the valve plate does not shift.

4, knife shaped gate valves can be equipped with handwheel, manual zipper, positive gear drive, bevel gear drive, pneumatic, electric and electro-hydraulic.

5, the knife shaped slurry valve can be made into V, triangle and five angle channels to suit the requirements of fluid regulation control.

6. The connection forms of the knife shaped sluice gate valves include the clamp type, the flange type, the metal seal, the metal to the polyamine, the reinforced polytetrafluoroethylene rubber and so on.

7, working temperature: soft seal (NBR) < 80 centigrade (PTFE): -40 C ~180 C carbon steel: -29 C ~425 C stainless steel: -40 C, ~600 C, Cr Mo vanadium steel: less than 550 C high chromium nickel steel: less than 900 C working pressure: 0.6, 1, 1.6MPa implementation standard: design according to JB/T8691-1998 flange according to GB/ T9113.1-2000 structure length according to B/T15188.2-94 test and acceptance by GB/T13927
