The Applications Occasion of Globe Valve

 If you want to Wholesale Cast Steel Butterfly Valve, Please note that these:

Cut-off valve, stop valve, Globe valve) of the opening and closing is plug valve, sealing surfaces appear flat or cone, disc make linear movement along the centerline of fluid. Stem form of exercise, there is lifting lever (valve rod, the handwheel do't lift), there are also lift rotating lever (hand wheel rotating lifting with the valve stem and nut in the body). Globe valve such as Cast Steel Globe Valve used throughout close tu, do't allow to adjust and throttling.

Check These Before Installing The Valve

Check before valve such as DIN Lift Check Valve installation:

Check whether the valve number and specification meet the requirements of the drawing carefully,after you buy from Gost Globe Valve Supplier or others.
Flange check valve stem and disc open for flexibility, no sticking and deflection.
Check valves for damage and correct and complete threads of threaded valves.
Check the seat and body firmly, disc and seat, cover and body, stem and disc connection.
Please check whether the valve gasket, packing and fasteners (bolts) are suitable for working medium properties.
Should be removed, dust, sand and other debris should be cleaned with water.
Check seal level. Disc must be closed tightly.

Butterfly Valve Transportation and Storage and Other Major Matters

When you Wholesale Cast Iron Butterfly Valve, The butterfly valves should be protected from bruising by two sealing surfaces during handling.

Butterfly valve should be stored in rainproof, dustproof, dry place, make the butterfly plate in an open state, 5 ° to 10 ° and coverage, to prevent debris into the sealing face.

When the electric butterfly valve leaves the factory, the opening and closing stroke of the control mechanism has been adjusted. In order to prevent power supply from wrong direction when it is turned on, the user should manually open to half-open position before switching on the power supply for the first time, and then press the button to check that the direction of the indicator disc is the same as that of the valve.

If the valve is not open or closed properly, the reason should be found out to repair and eliminate the valve. Yuanda valve company supply Butterfly Valve, Bellow Seal Globe Valve and JIS 10K Non-rising Stem Gate Valve. Welcome to our website know more.

How Does The Ball Valve Stand Out In The Valve Arena?

In the field of valve, there are many kinds of valves such as Gost Ball Valves. The reason why ball valves stand out and are frequently used in various fields cannot be separated from their irreplaceable advantages. So, what are the advantages of ball valves?

Above all, the advantage that ball valve cannot ignore is wear-resisting. According to the technical personnel inside course of study, to the valve, wear-resisting is the important factor that checks valve quality, the sealing ring material of ball valve is alloy steel surfacing welding, and general valve sealing ring is rubber or be other metal, these material do not have the alloy steel of ball valve surfacing welding wearability is good.

The Most Obvious Advantages And Disadvantages Of The Globe Valve

The most obvious advantages of globe valve such as DIN angle type Globe Valve are:

(l) during opening and closing, the disc is wear-resistant because the friction between the disc and the sealing surface of the body is less than that of the gate valve.

(2) open height is generally only l/4 of seat channel diameter, so it is much smaller than gate valve.

(3) usually there is only one sealing cover on the valve body and disc, so the manufacturing process is better and convenient for maintenance. But, the drawback of stop valve also cannot ignore.

The main disadvantage is that the flow resistance coefficient is relatively large, so pressure loss is caused, especially in the hydraulic device, such pressure loss is particularly obvious.
