Specifications

water oil gas rising casting steel rising stem gate valve
1.Class A sealing
2.DN50-600
3.can put your logo on the valve

1.Product description

The gate valve can only be fully opened and fully closed to be used for cutting in the pipe-

line. It has such features as unlimited installation direction, small disturbed current, low press-ure drop, shorter face-to-face dimension, good sealing performance and wide application range.

1.This kind of Russian standard valve reach Class A sealing effect and Guarantee no leakage

100%.It has widely used in the fields of oil and gas etc,under the pressure of 1.6 mpa.

2.Sealing surface is made of stainless,can serve a long life.

3.Use of flexible graphite packing,sealing and reliable,easy operation.

4.Brass yoke nut and stainless stem will never get rusty,more easy operation.

5.Ductile iron handwheel have enough tenacity and breakage-proof.

Packaging & Shipping

7.Packaging and Shipping:

Seaworthy packing:

(1)we usually use paking palletized to package our gate valve

(2)we also use plywood cases to package our gate valve

(3)One 20' container can in bulk loaded on 20pcs plywood cases more or less.

(4)We can pack according to specific customer requests.

(5)Customers' logos are available on package of the gate valve Pingyilu.

Slim Disc Wafer Butterfly Valve Cast Iron / Ductile Iron Material

REASONS FOR CHOOSE US

1.We are direct proucer of butterfly valves, check/non-return valves, gate valves and so on.

2.We can offer you most professional technical support.

3.All valves are tested twice before and after hammer pin to ensure its perfect sealing property.

4.Valves' back seats are phenolic resin under DN350 while above DN400 are aluminium back seat to prolong its working life.

5.Concentric valves can ensure zero leakge.

Q:How to identify the good or bad of the valve, without pressure test and instrument?: You can see what the material inside the valve ~ basically copper heart relatively durable, solid ~!

Q:What are the specifications of the valves PN25, DN50?: PN is the pressure. DN is caliber. In a nutshell, it's the valve of 25bar 50!

Q:What are the advantages and disadvantages of this method? Are there any other ways to adjust the flow rate?: This is the most widely used method of regulating flow, while protecting pumps and motors. The general classical installation method is as follows: the pump outlet is equipped with a vibration reduction joint, and then a gate valve control switch, and then install a multi-function water pump valve to adjust the flow.

Q:Measure the temperature with a thermocouple, and then how to make the valve open when the temperature reaches a certain value. When the temperature is lowered, will the valve be closed?Or tell my brother what is the knowledge, I can see it myself. Good. How much extra?!: A relay or PID controller can achieve this operation, only need to set out, the valve can use electromagnetic valve, which belongs to a rapid opening and closing valves, only need to control the electric power to the valve can automatically open or closed, but the temperature change is large, if you want to keep the temperature constant. The best selection of regulating valve, constant temperature control valve will be before or after the valve, the main electrical control knowledge, do not know what I said is clear, remember the points, thank you!

Q:Is the filter also valve?: The filter is in fact a low inlet and outlet shut-off valve with no disc and valve head. The filter screen is arranged in the middle, to control the filter according to the number of travel impurities. Usually follow the valve to tender, but not valves.

Q:Can the angle valve of York central air conditioner be replaced by other valves?: Definitely. But I want you to tell me what you're doing, or give me a picture. I can give you some advice

Q:What courses in the University involve valves?: Principles of Chemical Engineering (basic courses in chemical engineering and Technology)You always have to consider the problem of the valve when you design the pipe

Q:1) the valve plate, valve gate valve, the difference (my personal understanding is that if it is on the ball, called the valve, if the valve is called the gate, is actually a meaning in different valve called, please help me understand it right?)2) valve clack. What's the spool?3) the valve seat is welded inside the valve, or is it directly installed inside without welding?4) when opening the valve, if the valve seat is not welded, then, under the pressure of the medium, why not open the seat?.5) excuse me, pressure self sealing (my personal understanding is that when the valve is closed, the valve plate and valve seat depend on the pressure of the media, and they fit together to seal the effect: The first question is basically the same, and you can understand that for the secondThe 3,4 problem, there are several seat connections, such as thread connection (threaded, the valve seat is connected with the valve), modular connection (such as adding the cage to a fixed seat, the crushed) as one of the body and there is (some welding). The valve seat must be fixed.The fifth question, you are right!

Q:and today the boss told me that I would like to do a valve of the commodity inspection information, and nothing else to me, which master taught meI am a professional intern, our company is doing the valve outlet, today my boss asked me to do a valve inspection data, what other data are not for me, which foreign trade master teach me ah, depressed ah ah ah???: If the customs clearance order is required, the boxes, invoices, and contracts will not be needed. If the customs clearance is made, which port should be provided, the value of the goods, the weight, and the HS code for those

Q:What does LBC mean in a valve?: LB and 800 are together. 800LB means 800 pounds of stress, and P should be PRESSURE.Valve (Famen) is a control component in the fluid delivery system. It has the functions of closing, adjusting, guiding, preventing reverse flow, stabilizing voltage, shunting or overflow and releasing pressure.Valves used in fluid control systems, from the simplest stop valve to a very complex automatic control system used in a variety of valves, a wide range of varieties and specifications. Valves can be used to control air, water, steam, a variety of corrosive media, mud, oil, liquid metal and radioactive media and other types of fluid flow.
