Ductile iron valve factory

Product Description

Resilient seated gate valves are the perfect solution as a closing device in pipeline systems. Be suitable in applications with water supply, sewage treatment and neutral liquids in the mining industry, enterprises and high buildings.

We design and manufacture BS5163, DIN3352, AWWA C515/509, SABS664, AS2638, JIS B2062, socket end resilient seated gate valve etc.

Here we are introduce one type of our DIN3352 gate valve

Material List

No.	Part	Material

Q: What's the meaning of the "single valve"?: There are nuts, plants, flush three parts. The pipeline steel or steel ingot forging molding machine fittings, connection form the socket welding and threaded, socket welding steel pipe is inserted into the socket is in welding, so called "socket joint, thread connection pipe is screwed in the screw through connection.

Q: Remove the handle and lever the stem rotation with a wrench,: Monel alloy is mainly applied to the valve in the medium containing hydrofluoric acid.6, Hastelloy alloy is mainly used in the valve of strong corrosive medium such as dilute sulphuric acid7, titanium alloy is mainly applicable to all kinds of strong corrosive medium valveRecommendations for the GB standard of steel and ASME second A copies at American Standard. For American Standard steel can also see ASME B16.34

Q: What valves are needed on the construction site?: Depends on the actual size of the required diameter, how much work pressure, and then choose the right valve. Commonly used PVC, cast aluminum, cast iron; PVC cheap, commonly used in small diameter pipe, cast aluminum, cast iron is relatively expensive, high pressure.

Q: What is the difference between the valve before the pump and the valve after the pump?: Before the pump few valves, up to a foot valve, pump valves, convenient maintenance, then the most important is that the action of check valve backflow, water hammer....

Q: Is there any problem with connecting the geothermal valves with other geothermal pipes?: Can be universal,Material is the same, the fuse will not cause shrinkage when you can use

Q: What courses in the University involve valves?: Fluid mechanics, "material mechanics", "mechanical design" and other courses on the design of the valve are helpful.

Q: What does "DN15" mean? What does "PN 16" mean?: Valve nominal diameter 15mm, valve nominal pressure 1.6MPa

Q: What should be checked before using the valve?: The valve must be tested before installationI. examination of documentsThe valve must check the quality documents before installation, the valve manufacturer should be nameplate, nameplate and the body should be the name of the manufacturer, valve type, nominal pressure, nominal diameter and logo, must comply with the "universal valve logo" GB 12220.Two, appearance inspection

Q: Why can't the clip type check valve be directly connected with the pipe mouth or other valves?: The clip type check valve is made up of two discs to prevent backflow.If the clip check valve is connected to the other valve, the disc may touch the valve and cause the check valve not to be fully opened or closed. This is a preliminary analysis of "enter the valve", for reference only!
