Needle valve installation convenient disassembly, petition fastening, helpful to fire, explosion and high crushing experienced, tight sealing performance is satisfactory, such as strength, is the power station, oil refining, chemical industry equipment and instrument survey line of an advanced valve in the form of a petition. Type needle valve is a valve can be very accurate debugging used widely, such as flame cutting with the cutting distance, debug the flame temperature knob is the needle valve, instrument calibration type needle valve is shut up in the local instrument survey line system, mainly by the valve and ball valve, its purpose is for open or truncation pipeline path. No matter what the effectiveness of the valve is to cutting fluid. On the basis of the valve core is different, can be divided into by the valve, gate valve, plug valve, ball Industrial Valves, butterfly valve, needle valve, etc. Needle valve valve core is a very sharp cone, like the needle in the same seat, hence the name. Needle valve type than any other type of valve that can tolerate more pressure, tightly sealed performance is good, so common for small flow, high pressure gas or liquid media tightly closed. Needle type Marine valve and pressure gauge appropriate use is the most appropriate. Ordinary type needle valve type into a turnbuckle signatures. 。 Manually by the end of valve, ball valve can be installed on the line no matter what position. Q: the office principle of needle valve type introduce a: needle valve type: is shut up in the local instrument survey line system, there are mainly by the valve and ball valve, its function is for open or truncation pipeline path. Type needle valve tightly closed satisfactory, use fixed number of year long to survive, even if the tightly closed surface after destruction, also just change quick-wear part, can be used. When installing type needle valve should make the flow of the medium and the direction of the arrow on the valve body are exactly the same. Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you. Second, if the valve has been selected by design unit of our company model, please order according to the valves parameters directly with our sales center.
