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
Grey cast iron/ductile iron + fusion bonded epoxy coating
Grey cast iron/ductile iron + NBR/EPDM/FPM
Stainless steel 2Cr13
Stem nut, bushing
Features & Advantages
Stem sealed with O-rings: realize zero leakage, O-rings could be replaced under full pressure.
Bolted bonnet, full bore: used for larger valves and higher pressure applications.
Blue fusion boned epoxy coated inside and outside: suitable for portable water.
Working pressure from -1 to +16 bar and working temperature from -10 to +80°C

Q:Valve and pipe correspondence
The pipe you choose is outside the 60 bar D60 pipe DN50 valve is right, such as D89 pipe with DN80, you are outside diameter and nominal diameter concept is not clear
Q:Which direction is the valve? Which direction is it?
Ball valve: handle and Guan Daocheng 90 degrees for the pass, 180 degrees to open (ie in line with the direction of the pipe open)The gate: clockwise, counterclockwise.
Q:Where is the Shanghai valve? What brand is good?
Shanghai Dapu Valve Co. Ltd.Amico jiekelong shield, doing a good job
Q:What is a hot melt valve?
For the pillars of the temple are scattered on both sides,I first saw you when I was about to leave.The prey in the net is a star.Far away, where you are nowBecause I love you。For a very Chinese, this ha ha!
Q:How about the quality of FITOK valves?
Purely under the banner of what import, in fact, everyone knows, is the genuine domestic goods.
Q:Can the gas valves be switched off regularly?
No one at home, there are children, stove use time is relatively long, the gas hose has not changed for a long time, as far as possible off the stove front valve. Regular checks are necessary. For a long time, try the stove before the valve is intact, hose aging, safety first. Selection of large brands of stoves, quality guaranteed
Q:How can the material be checked by valve approach? What experiments do you need?
May refer to the valve pressure test principle and the pressure test matters needing attention.(1) in general, the valve shall not be subject to strength test, but the body and bonnet shall be subjected to strength tests after the repair of the valve body and bonnet or corrosion damage. For the relief valve, the constant pressure and seat return pressure and other tests shall be in accordance with the specifications and the relevant regulations.(2) the installation of the valve should be done for strength and tightness test. Low pressure valve sampling 20%, if not qualified should be 100% of the inspection; medium and high pressure valve should be 100% of the inspection.(3) the installation position of the valve shall be in the direction of easy inspection during the test.(4) welding connection valve, not with blind plate pressure test can be used when the cone seal or O ring seal pressure test.(5) when hydraulic test, the valve air will be excluded as much as possible.(6) the pressure should be increased gradually during the test, and the pressure will not be sudden and sudden.(7) strength test and sealed test duration is generally 2~3min, important and special valves should last 5min. Small caliber valve test time can be a little shorter, large caliber valve test time can be longer. During the test, the test time can be extended if in doubt. Strength test, does not allow the body and bonnet sweating or leakage. Sealing test, the general rotor valve only once, the safety valve, high pressure valve and other raw valve to be carried out two times. When testing for the low pressure, large diameter valve is not important and there are provisions to allow leakage of the valve, allowing a small amount of leakage; the common valve, power station valve, marine valves and other valve requirements vary on leakage requirements according to relevant regulations.
Q:How much is the 150LB of the valve?
The valve according to the material is divided into cast iron valves, cast steel valves, stainless steel valves (201, 304, 316), chrome molybdenum steel, chromium molybdenum vanadium steel valves, valve, dual phase steel valves, plastic valves, non-standard customized valve material etc..
Q:How many valve enterprises in China's valve industry?
How much? I don't know. It depends on what valve you need. Hebei iron and steel Wenzhou, needle valve Funing, Anhui Tongdou valve. Do not want to buy a high price of Shanghai valve, look at your specific needs
Q:Symbols for all types of valves
In addition to the throttle valve (L) valve (H) valve (U) valve (Y) of the four types of valves, the other is according to the first letter of the easy to remember the four valve but also second word the first letter and the other valve is repeated with the first letter of a very good record I was just valve knowledge I hope to help you!
