Q:D341W-10P-400 butterfly valve, what does each alphanumeric letter mean?
According to JB/T308-2004 "valve type programming method"D butterfly valve3 worm gear4 flange connection1 Structure: sealed type, central vertical plateW sealing material for valve body material10 nominal pressure PN10P body material is chromium nickel stainless steel400 shall be nominal size DN400
Q:How do you explain A in butterfly valve D37A1?
Represents a seal or lining material symbol.Said sealing ring or lining material with the Chinese phonetic alphabet: B Babbitts D nitrided steel, acid resistant stainless steel H, J L Aluminum Alloy, hard rubber, nylon NL, P leather, SA PTFE, SC PVC, SD bakelite, T copper, TC enamel, X rubber, Y hard alloy
Q:What's the difference between D71X-16 and D71H-16 butterfly valves?
Model D71X model means this, D represents butterfly valve, 7 represents butterfly connection form for clip type connection, 1 represents straight through, and 16 represents pressure 16 kg pressure.X stands for sealing and soft sealing, and the sealing surface is usually nbr.H stands for metal hard sealing, usually 2Cr13 surfacing.D71X-16 butterfly valve featuresIts main features are:1 、 the design is novel, reasonable, unique structure, light weight, fast opening and closing.2 、 small operating torque, easy operation, labor-saving and smart.3. It can be installed and maintained conveniently in any position.4, seals can be replaced, sealing performance is reliable, to achieve two-way sealing, zero leakage.5, sealing materials aging resistance, corrosion resistance, long service life and so on.
Q:Butterfly valve, two-way pressure and one-way pressure what is the difference?
One way sealing butterfly valve is the front of the butterfly valve. When it closes, it must face the direction of the medium. The medium flows only in one direction, and the arrow on the valve body indicates the direction of the flow direction of the medium. Attention should be paid to the flow direction of the medium during installation. Two way butterfly valve is butterfly plate can face or back to the media flow direction, installation without attention to medium flow direction, in the valve body also does not indicate the direction of the medium flow arrow. Two way sealing butterfly valve stem force is greater than one-way butterfly valve stem. Design, the same diameter, pressure butterfly valve, two-way sealing butterfly valve rod diameter than one-way sealing butterfly valve stem diameter.
Q:Will A Stop Valve Switch Off Water In The Bathroom Only
Water should be off to the sink is the stop valve off
Q:What's the difference between a clip type turbine butterfly valve and a flanged turbine butterfly valve?
For clip butterfly valves, there are no flanges at the ends of the butterfly valve. There are only a few guide bolts. The valve is connected with the end flange with a set of bolts / nuts.In contrast, the demolition to facilitate some of the lower cost of the valve, but the drawback is that a sealing surface problems, the two sealing surfaces have to be taken apart.Flange butterfly valve at both ends of the flange, and pipe flange connection. The seal is relatively more reliable, but the valve is of relatively high cost.
Q:My eletric hot water tank started spraying water out the pressure valve?
If you have replaced the TP valve, more than likely there is a heating element shorted to the tank. This will cause continuous heating and high temp/high pressure...good luck.
Q:D37A1X9-16CB1: what does this butterfly valve mean?
The model is composed of 7 units, the types of valves (gate valve Z, J, L, Q ball valve, throttle valve, check valve and H valve, butterfly valve, connection mode (D) internal thread 1 thread 2, welding flange 4, 6, 7, the clamp (0) electromagnetic transmission mode 1 solenoid valve, hydraulic, electric and hydraulic turbine are 2, 3, 4 and 5 gears, bevel gear, pneumatic hydraulic, 6, 7, 8, 9) pneumatic and hydraulic, electric, structure (straight or DC type 7,1 on behalf of the center plate, vertical type A (A) and LT X9) on behalf of a sealant is heat-resistant rubber, kg 16 kg, C represents the body material of carbon steel WCB, B1 on behalf of the valve plate is made of ductile cast iron plating)
Q:How do the butterfly valves d341 and d343 differ in appearance?
A difference in appearance:D341 is a wedge type single gate structureThe D343 is a parallel single gate structureIn addition, the structure is different. D341 butterfly valves are single eccentric, while the D343 is three eccentric. Three eccentric can do zero leakage, and single eccentric can not.D341:D: butterfly valve (die, the first letter of Pinyin)3: turbine drive (6) for pneumatic, 7 for hydraulic, and 9 for electric)4: flange connection (this additional: 7 for the pair, 6 for welding)1: midline form (another supplement: 2 represents double eccentric, 3 represents three eccentric)D343:D: butterfly valve abbreviation3: hand wheel drive4: flange type3: three eccentric.
Q:Which is more expensive, gate valve or butterfly valve?
Gate valves of the same material and specifications are much more expensive. The weight of the gate valve is much heavier than that of the butterfly valve.
