PN16 Non Rising&Rising Stem Ductile Iron Gate Valve DN50-DN600

The products are widely used in water source projects, urban water supply and drainage,
sewage treatment, electric power, petroleum, petrochemical , heat supply,
shipbuilding, medicine and metallurgy industries. Equipment are used for regulating
or cutting off media in pipelines. Suitable media include water, sewage, sea
water, air, foodstuff and oil. Suitable for gear operators, electric and pneumatic
control actuators.

Q: Gate valve Z41H-16Q generally used for what place?: Gate valve is one of the most commonly used cut-off valve, mainly used to connect or cut off the medium in the pipeline, not applicable to regulating medium flow. Suitable for medium and large diameter pipelines.

Q: What is the standard for ductile iron gate valve set?: Clear shot valve installation, is still under way of connection and specifications set "water supply and drainage, heating, gas engineering" or "industrial engineering" pipeline register quota corresponding specifications and installation methods of connecting the valve installed valve section.

Q: What is a protective gate valve? What is gate valve knowledge?: Explosion-proof valve products, is a kind of safety valve can eliminate the shock wave which can stop the water hammer shock wave, it is a product composed of multiple sets of safety,

Q: Gate valve z45h-10dn250 length of the body?: Z45h-10dn250 body length L=330mm, this valve is hidden bar, elastic seat, sealing gate valve, gate lining, lining fluorine, belong to soft seal

Q: Stainless steel gate valve DN150 200300 weight, who knows?: It depends on different materials and pressure levels. 304 material, high pressure weight will be much heavier.

Q: What's the meaning of flexible z45x-10q door valve?: Crown valve pressModel Z45X-10QZ refers to gate valve4 finger flange connection5 refers to the dark bar driveX refers to rubber seals10 refers to 10 kg pressureQ refers to the body material, ductile ironFull bore flange soft sealed gate valve

Q: What is the gate valve for the DN65 hydrant?: DN150, of course. Ask me about fire protection

Q: Notes on flat gate valves: internal structureThe 1 seat O ring seal and preload floating seat structure, so that import and export of two-way valve seal plate; and the structure of the normal valve opening and closing torque only 1/2, can easily open and close valves2. when fully open, the channel is smooth and straight, the flow resistance coefficient is extremely small, and there is no pressure loss. The pipeline can be cleaned through the hair bulb3 the packing structure with the ability of self sealing, without frequent adjustment, opening and closing very lightweight, and reliable seal, the stuffing box is arranged at the auxiliary seal oil into the structure, absolutely reliable sealing performance, thereby achieving zero leakage; solve the shortcomings of the general valve packing leakage of the most vulnerable4., when the flat gate valve is closed, it can automatically unload the inner cavity high pressure, and ensure the safe use5., fully enclosed structure, good protection performance, can adapt to all-weather requirements6., the valve seat sealing structure should be elastic, preload, upper and lower sealing seat at the same time sealed structure. The valve seat and the seal are always face to face sealed.The 7. seat has self-cleaning function and is free of direct airflow during valve opening or closing. The seat shall be made of lubricated, non wearing material.8. valve actuator failure will not affect the other parts of the valve, maintenance and replacement work can be carried out without removing the valve.9. yoke sleeve aluminum bronze yoke sleeve with pin type thrust bearing to minimize operation torque.10. stem - thread length until bracket; dowel and spot welding; stability.11. pressure seal - simple construction, with sectional retaining rings and silver plated low carbon steel gaskets, helps to remove and achieve the best bonnet seal.12. seat ring - welded seat ring is perpendicular to the flow channel and is easy to maintain.

Q: Gate valve z41t what does that mean?: According to the provisions of the JB/T 308-2004 valve type programming method:Z = gate valve4 = connection form: flangeT = sealing surface material: copper alloy

Q: Why does the centrifugal pump start and stop in the case of closing the gate valve?: The centrifugal pump starts and stops in the case of closing the pump outlet valve. Start off the pump outlet valve is to reduce the starting current, stop when the pump is closed, the outlet valve is to reduce water hammer, prevent blade from bad.
