Q:What does the butterfly valve D361H - 25C DN350 mean?

Welded turbine butterfly valve, hard seal, material: cast steel, pressure 25KG, caliber 350MM

Q:Three eccentric hard sealing butterfly valve, why not fit in the end of the pipe?

The sealing ring will hold up. It does not fit in with the flange end of the pipeline, this addition is the most common and convenient pipeline after purge and easily add pipeline.

Q:How can the flange butterfly valve be installed on the pipe?

Direction.Butterfly valve in theory can be installed in any direction, it is recommended that the horizontal installation of the valve shaft installation, so that both ends of the bearings will not be at the bottom (below), so as to avoid sediment in the media into the bearing.Inlet pipe configuration.There are water inlet side valve elbow, tee pipe fluid caused by bending and uneven distribution of the inflow valve, the drift will occur in the pipe, so it must be generated by the uniform drift disposed on both sides of the disc, so as to avoid uneven force on both sides of the disc, and may produce additional torque.

Q:Butterfly valves are widely used in 2.0MPa below the pressure and temperature of not more than 200 degrees of various media, right?

3. kinds of butterfly valve:According to the connection mode: flange type, clip type.According to the material of sealing surface, soft seal and hard sealing.According to the structural form, butterfly valves can be divided into the following types:Plate typeInclined plate typeOffset plateLever type4. butterfly valve features:(1) the structure is simple and the shape is small. The utility model has the advantages of compact structure, short structural length, small size and light weight, and is suitable for large caliber valves.(2) the resistance of the fluid is small, and when the valve is fully opened, the valve seat passage has an effective circulation area, so the fluid resistance is smaller.(3) open and close, convenient and quick, good adjustment performance, butterfly plate rotation 90 degrees can be completed headstock. By changing the angle of rotation of the disc, the flow can be graded.(4) the opening and closing moment is smaller, because the butterfly plate on both sides of the rotating shaft is basically equal to the medium, and the opposite direction of the torque is generated, so that the opening and closing is more labor-saving.(5) low pressure sealing performance, sealing surface materials generally use rubber, plastic, sealing performance is good. Limited by the material of the sealing ring, the pressure and the temperature range of the butterfly valve are smaller. But the use of hard sealing butterfly valve pressure and temperature range has been greatly improved.

Q:1st where is my zone valve? I have an old Burnham gas baseboard heater2nd What do I do?My last resort is calling a proffesional.

First: Wat make you tinkling that the zone is bad? Every zone cooperate with 2 other essential parts: thermostat and power supply, In 90% of my carea, people firs go with their thinking to zone, but only 10% was realy zone. The first thing to check is termostat and power. you could do this very simply by removing termostat wire and tickling them together several times, if they have spark, than the most prabably is just thermostat broken

Q:How does PLC control butterfly valves?

PLC control butterfly valve, usually control pneumatic butterfly valve or electric butterfly valve.PLC control pneumatic butterfly valve, that is, PLC program control, electric control, gas control, gas control butterfly valve;PLC control electric butterfly valve, that is, PLC program control electric, electric control butterfly valve.Control requirement:All PLC output contacts must be isolated from the intermediate relay and indirectly controlled by an intermediate relay.

Q:How big is the butterfly valve with a diameter of 80?

With the 80 caliber butterfly valve.Also known as butterfly valve, control valve has a simple structure, can be used for low pressure pipeline valve switching control is closed parts (disc or disc) is a disk, around the valve axis to achieve the opening and closing a valve, the valve can be used to control the flow of air, water, steam steam, all kinds of corrosive medium, mud, oil, metals and radioactive liquid media and other types of fluid.

Q:My caravan is a bit sluggish on the pick up, I replaced the wires/plugs and the electronic distributor(I think thats what it is..). still a bit sluggish. Should i look at the valve gasket? Or fuel filter, or fuel pump next? 03 caravan sport 3.3L

the valve pan gasket won,t cause it but the fuel filter will if it,s starting to clog up and also the cat nverter !

Q:What's the difference between cut-off valve, gate valve and butterfly valve? What's the difference in the working principle?

Gate valve, also known as gate valve, is a widely used valve. Its closing principle is that the gate sealing surface and the valve seat sealing surface are smooth and smooth, and they fit together to prevent the flow of the medium, and rely on the die shape of the top die, spring or gate to enhance the sealing effect. It mainly cuts off in the pipeline. The cut-off valve, also called the door, is the most widely used as a valve, it is popular is because the process of opening and closing the sealing surface friction between the small, more durable, highly open small, easy manufacture, convenient maintenance, not only for low pressure, but also suitable for high pressure. Butterfly valve with light characteristics, more than other valves to save material, simple structure, quick opening and closing, cutting and throttling can be used, the fluid resistance is small, labor-saving operation. Butterfly valve can be made into large caliber. Where you can use the butterfly valve, it is best not to make the gate valve, because the valve is more economical than the gate valve, and the regulation is good. At present, butterfly valves are widely used in hot water pipelines.

Q:What is the principle of butterfly valve and check valve? Any difference?

Direct water butterfly valve, check valve is to water can not flow valve
