Q:The difference and use of gate valve and stop valve

Medium flow is unrestricted.When opening fully, the sealing surface is eroded by the working medium smaller than the cut-off valve.The shape is relatively simple and the casting process is better.The valve is used in the system is relatively large, to close the gate off system; and the valve is used in the system is relatively small, and to adjust the flow quantity of the system, can not be closed gate and globe valves of different specifications for many kinds of occasions, the valve rod valve the dark bar gate valve, wedge gate valve, single valve, multi valve valve body structure is different, large volume.

Q:What does gate valve do?

Gate valve structure, upstairs said about the same, but it can only rough adjustment flow, you may drive it to 30%, he will flow through 65% traffic, you can drive him to 70%, he also flow through 75% traffic. However, the fluctuation is small and can be used for rough adjustment of flow. What's more, half open and half closed are some of the effects on their life span.

Q:Z41T one 10 gate valve and Z44T one, 10 gate valve difference

Z41T one, 10 is single gate, Z44T one, 10 is double gateAccording to the provisions of the JB/T 308-2004 valve type programming method:Z== gate valve4== connection: flange type1== structure: Rigid single gate4== structure: Rigid double gateT== sealing surface material: copper alloy10== pressure rating: 1.0MPa

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 is the difference between the copper gate valve and the ordinary material gate valve?!

The copper gate valve is made of copper alloy, and the common materials are made of stainless steel, cast steel, cast iron, and so on. Now there are new types of ceramic gate valves. Different properties of the gate valve performance, processing technology, service life, applicable occasions are a certain difference. Copper gate valves should be used for fire end water outlet installations as well as other occasions with special requirements.

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.

Q:What does the gate valve SZ45X-1.0 stand for?

A modelModel SZ45T-1.0, especially in DN100 ~ DN300 piping, soft sealing gate valve shall be used

Q:The difference between flanged gate valve and common gate valve

General diameter of more than 50 with flanges, inspection wells, main pipes, trenches... Must use flange gate valve, good operation, good replacement.

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:Why is gate valve or butterfly valve used for water pump?

General pressure is small, use the butterfly valve, when the pressure is big, use the gate valve. The two main function of the valve is to adjust the flow and easy to overhaul.Zibo Boshan new Duke water supply equipment
