Q:what are their applicable conditions? Advantages and disadvantages?

Valve is closed parts (RAM) along the vertical axis of the mobile channel valve in the pipeline, used primarily as a medium cut that open and close, generally do not have to do with traffic regulation, it can be used for low temperature and low pressure can also apply to high temperature and high pressure, and according to the different valve material for different media. In various types of valves, gate valve is the most widely used.Advantages: low fluid resistanceSmall torque required for opening and closingYou can use the ring road in which the medium flows in the two direction, that is to say, the medium is free of flowWhen fully open, the sealing surface is less eroded by the working medium than the cut-off valveThe structure is simple and the manufacturing process is betterThe structure length is shortDisadvantages: the overall size and opening height are larger, the space required for installation is also largerIn the process of opening and closing, there is relative friction between the sealing surfaces, and wear more easily, and even cause friction at high temperatureGeneral gate valve has two sealing pairs, to the processing, grinding and maintenance increased the number of difficultiesLong opening and closing time;

Q:What is the standard for ductile iron gate valve set?

Q:Z45T-10 what kind of material is the gate valve?

Z45T-10 refers to the nominal pressure of 1Mpa gray iron valve. The meaning of letters and numbers is:(Z) - gate valve;(4) indication - internal thread connection;(5) indicating dark wedge rigid single gate;(T) - the body is made of copper or copper alloy;(10) indication nominal pressure 1 mpa.Is the gate valve opening and closing parts, RAM direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle. The gate has two sealing surfaces, and the two sealing surfaces of the most commonly used gate valves form wedge and wedge angle valves.
