Gas valves. Price and quality
Each valve has a standard design. Consists of a rotating tube, that is, moving parts, and body, which is stationary. Gas control valves, in turn, consist of a body with flanges, rings, saddles, ball and guide rings.
Gas valves can give the following characterization:
- They are divided into three types, depending on the variety of the sealing surface, which has a shutter: spherical, conical and cylindrical.
- There is also a division of Gas valves and full-narrowed. In this case, the difference between the two named species is noticeable even a layman. All a matter of narrowing the passage. If it is, then we face the narrowed valve. And vice versa. Full bore Gas valves, for which the price varies from 350 to 6100 dollars (depending on size) made of 316 marks.
- Pass the crane may resemble the form of an oval, circle, trapezoid and a rectangle.
- Materials for valves used iron and steel, titanium, bronze, brass and plastic, as well as some other metals and alloys. For example, stainless steel taps, no fear of corrosion, are used for industrial purposes, and plastics can be used in apartments. That is the choice of material depends on with what the working environment crane will be used. Thus, domestic brass Gas valves are about 70 to 660 dollars. Maximum weight is two kilograms, the minimum – 138 grams.
The importance of large Gas valves: no gas pipelines, oil pipelines of state, no water and heating systems, which provide our homes with heat and water, can not do without them. Therefore, purchasers of Gas valves are as individuals and entrepreneurs, as well as housing and communal services, construction and industrial organizations.
High demand, high supply. Ball, for which the price is acceptable, are presented in a wide range in the Russian markets. There are both standard products made of brass, and special made for specific conditions or under the order. Needless to say, Gas valves, for which the price is available – from $ 100, then have the good quality. Because the experience allows manufacturers to produce them quickly, at low cost, efficiently. One of the conditions is the availability of quality testing using instrumentation in the last stage of production.

Ball, whose value is determined by the manufacturer, is a variety of valves. The mechanism of action is this: its opening / closing occurs when you turn the lever at ninety degrees. When it opens the pipeline and valve lever are parallel to each other. Ball, whose value is the ability to enjoy even retail customers (100, 130, 250 dollars), are another species – with floating flanges. It can be installed in all positions, not aligning with the mounting holes. This circumstance makes it possible to speak of the highest possible seal the joints and the possibility of multiple mounting. This valve is used in a variety of environments. Such as water, gas, steam, oil products. Very low hydraulic resistance, withstands pressure up to 1,6 MPa and a temperature of minus 50 to plus 150 degrees Celsius. Ball going Weld serve as locking devices designed to block the flow of matter (all media, except toxic ones). They can also be put on an already running pipes to replace the old valves. Withstand pressures up to 16 MPa, temperature variations from minus 30 to plus 200 degrees. These Gas valves are from 1000 to 162,300 dollars. Material – steel.
