Q:Where is the PCV valve?
top of the manifold
Q:What's the difference between turbine butterfly valve and manual butterfly valve?
The turbine can light and close the valve here. It is more labor-saving and reliable. It is closed and open. Manual operation is relatively difficult, but the manual action is very fast. Fast switching. General large bore turbine.
Q:How warm is the PTFE butterfly valve?
The normal temperature can be kept at 120 degrees and the instant temperature is 150
Q:The difference between the electric control valve and the electric butterfly valve, respectively, the application situation
Butterfly valve switching speed, fluid resistance is small, but the flow control is not good, suitable for only fast opening and closing occasions. Control valve switching speed is relatively slow, fluid resistance, but the flow control of the linear good, suitable for flow control requirements of the occasion.
Q:That industry uses most of the butterfly valve, and only use the butterfly valve, a large number of use of butterfly valve, seek expert advice!
Large diameter heating pipes with more than butterfly valves, greater than or equal to DN600 are used butterfly valve
Q:Which is expensive, butterfly valve?
The same material and caliber, butterfly valve structure is simple, less wood, the price is much lower than the gate valve, especially for clip type butterfly valve.
Q:Is a valve gasket the same as a valve cover gasket?
Don't okorder.com they cost $41.35 for both of them. Fel-pro is the brand name of these gaskets. #2. The valve stem seal kit costs $28.20 and again, Fel-pro is the brand neme. First of all does your car smoke slightly when you decelerate? If not there's absolutely no reason to bother having these seals installed. If the car does smoke when you decelerate valve stem seals are nothing but a stop gap for the real underlying reason the car smokes.
Q:What does the model D373H-16C of butterfly valve mean?
D373H-16C said: D type butterfly valve butterfly valve 3 said, said 7 of the turbine, said clip, 3 said the three eccentric (swash plate), 16 C nominal pressure, said carbon steel. In fact, if you want to understand this, to understand the valve 3.07ghz, later met have to be attached to the valve. 3.07ghzModel for valves, valve number indicates valve type valve should normally be that type, drive type, connection type, structural features, nominal pressure, sealing surface material, body material and other factors. Standardization of the valve type of valve design, selection, distribution, provide more convenient. The type of valve types and materials are more and more more models of the preparation of the valve will become more and more complicated. Although the preparation of our valve type unified standard, but gradually can not meet the needs of the valve industry. At present, the valve manufacturer usually adopt a unified numbering; not uniform numbering, the manufacturer can make out no.methods according to their own situation. Unit two unit three unit four unit five unit six unit seven unit
Q:What are the major disadvantages of butterfly valves?
Rubber elastomer in the butterfly valve will cause tear, wear, aging, perforation and even shedding in continuous use. The traditional heat curing process is difficult to adapt to the needs of on-site repair. It is time-consuming and laborious to use special equipment when repairing, and it consumes a lot of heat and electricity. Nowadays, polymer composite method is gradually used instead of traditional method.
Q:What does the butterfly valve D361H - 25C DN350 mean?
Corrigendum: correct type: D361H-25 DN350Should not have C, nominal pressure above 1.6MP carbon steel valve material code name should be omittedValve: central vertical plate welded turbine butterfly valve, nominal pressure 25kg, caliber 350mm, body material, carbon steel, sealing surface material: Cr13 stainless steel
