Q:What is the difference between an elastic gate valve and a rigid gate?
Brief introduction: the valve gate valve is a gate 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. Gate has two sealing surface, the most commonly used mode gate valve of the two sealing surface to form a wedge, wedge angle with valve parameters vary, usually 50, medium temperature is not high when 2 degrees 52'.Wedge gate valve can be made into a whole, called the rigid gate; can also be made to produce micro deformation of ram, in order to improve its process of deviation, make up the sealing surface angle in the process, the gate is called the flexible gate.
Q:The difference and use of gate valve and stop valve
Standard light valve professionals to answer for you, gate valve refers to the closure of parts (gate) along the central line of the vertical direction of moving valve. The gate valve is mainly used for cutting in the pipeline. The valve is a valve with a very wide, cutting device general caliber DN = 50mm use it, sometimes a small diameter cutting device also use valve, gate valve has the following advantages:Fluid resistance is small.Minor force needed for opening and closing.
Q:What are the specifications of the gate valves? Does the work pressure need to be marked separately?
5- dark pole single wedge gate valve, 6- dark bar wedge gate valve 7-, dark bar parallel gate valve, parallel gate valve 9- dark bar;5, sealing materials or lining materials were used R- T- austenitic stainless steel, copper alloy, X- rubber, S- plastic, N- nylon, F- fluorine plastic, H-Cr series stainless steel, hard alloy Y-, J- rubber, M- Monel alloy, Tc- ceramics;6, the body material code Z- K- gray cast iron, malleable cast iron, Q- ductile iron, copper and T- alloy, C- steel, P- chromium nickel stainless steel, R- stainless steel chromium nickel molybdenum, chromium molybdenum vanadium steel V-.For example: electric, flanged, rod wedge gate valve, sealing surface material by direct processing, nominal pressure PN0.1MPa of the valve body is made of grey cast iron gate valve: Z942W-1 electric wedge gate valve.
Q:The difference between flanged gate valve and common gate valve
Flange valve: English name; Flange Gate Valve is the gate 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. Gate has two sealing surface, the most commonly used mode gate valve of the two sealing surface to form a wedge, wedge angle with valve parameters vary, usually 50, medium temperature is not high when 2 degrees 52'. Wedge gate valve can be made into a whole, called the rigid gate; can also be made to produce micro deformation of ram, in order to improve its process of deviation, make up the sealing surface angle in the process, the gate is called the flexible gate.Ordinary gate valve: mainly used to connect or cut off the medium in the pipeline, not applicable to regulating medium flow. Gate valve applies to pressure, temperature and caliber range is great, especially for medium, large diameter pipesThe most important difference: flange gate valve and ordinary gate valve is different, flange gate valve quality, durable, easy to install, but higher prices, generally used for large pipelines. Ordinary gate valves are used for small caliber, easy to change places.
Q:What type of flange does it fit with the gate valve?
This depends on the type of gate valve, valve standards are marked with matching flange standards. Different types of flanges for different gate valves are also different.The flange of General GB gate valve is GB/T9113 series.
Q:What is the difference between the cut-off valve and the gate valve?
Selection of stop valve:There are two ways to install the valve, one is the media flow from the top of the spool, the advantage is that when the packing is not under pressure, the pressure can be replaced before the valve packing, there is a long service life characteristics. Another is the media from the bottom of the spool into, and its shortcomings are driving torque is large, is 1 times above the flow, the stem by the axial force of large, easy to bend the stem. Generally suitable for small caliber manual stop valve, to stop the valve closed, the media acting on the spool of force is not greater than 350kg limit. Electric cut-off valve is generally used to enter the media from the top way.Selection of gate valve and stop valve:Valve than the valve structure is simple, better sealing, manufacturing and maintenance to be convenient; shortcomings are fluid resistance, power, and opening and closing efforts. Gate valve, stop valve are fully open, fully closed valve, suitable for making cut off, it is not suitable for use as regulating valve. The application process should pay attention to the characteristics of the valve when selecting. Small pipes and better sealing performance generally use cut-off valve; in the steam system and large diameter pipeline, due to fluid resistance is small, suitable for use gate valve.

Cast iron gate valve with turbine head, please contact me
Q:What does P54100V mean in power station gate valve Z960Y-P54100V?!
P work pressureP54 temperature at 540 degrees of work pressureThe pressure at P54 100 is 540 at the temperature of 100barV valve for chromium molybdenum vanadium steelP54 pressure 140V temperature at 540 DEG C for 140bar valve for chromium molybdenum vanadium steelP54 pressure 170V temperature at 540 DEG C for 170bar valve for chromium molybdenum vanadium steelFrom the JB/T4018 "valve type model preparation method"The standard unit is MPa, but it is usually used in bar
Q:Function of gate valve
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.
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
