Product Description:

Forged steel & Cast stelel Pressure Seal Globe Valves

The characteristics of Forged steel & Cast stelel Pressure Seal Globe Valves:


1.Globe valve's structure is moresimple than gate valves, and it is more convenient in manufacturing and maintenance

2.Sealing surface is not easy to wear and scratch, and it has a good sealing surface and long service life.

3.When opening and closing, disc's route is small, so the height of globe valve is smaller than gate valve, but the length of structure is longer than gate valve's.

Usage/Applications Of Forged steel & Cast stelel Pressure Seal Globe Valves:


Globe Valves are mainly used to modulate or regulate a fluid's flow. A Globe Valve is not recommended when a continuous full flow of fluid is required due to the high pressure drop inherent to the design of a globe valve. This type of valve should always be installed so the flow intake enters through the base of the valve seat. Valves may be used with fluids containing particles in suspension, widely used in process and petrochemical applications, have high corrosion resistance and find wider application within the food and fine chemicals industries.

Q:Which direction is the valve? Which direction is it?
Generally: clockwise, counterclockwise, looseYou can also see the logo on the spool
Q:What is the choice of pneumatic valve or electric valve for ultrafiltration inlet control valve?
Now the UF system is basically full automatic system, that is to choose automatic valve. As for the pneumatic valve or electric valve, depending on your investment and the scene.
Q:What are the general types of valves?
Pneumatic and hydraulic valvesPneumatic valve and hydraulic pressure based on a certain air, water or oil as the power source, using the cylinder (or cylinder) and the movement of the piston to drive the valve, the general pneumatic air pressure is less than 0.8MPa, the hydraulic or hydraulic pressure is 2.5MPa~25MPa. Such as used to drive diaphragm valves; rotary gas and liquid drives are used to drive ball valves, butterfly valves, or plug valves. The driving force of the hydraulic device is large, and it is suitable for driving large diameter valves. If used for driving plug valves, ball valves and butterfly valves, the reciprocating motion of the piston must be turned into a rotary motion. In addition to the cylinder or hydraulic cylinder piston to drive, but also the use of pneumatic film driven, because of its small stroke and driving force, it is mainly used for regulating valves.Manual valveThe manual valve is the most basic way of driving the valve. The utility model comprises a hand wheel, a handle or a plate hand, and is driven directly and driven by a transmission mechanism two kinds. When the starting torque of the valve is large, it can be driven by gear or worm gear to achieve the purpose of omitting. Gear drive, spur gear drive and bevel gear drive. Gear reduction ratio is small, suitable for gate valve and stop valve, worm gear drive is relatively slow, suitable for cock flashing, ball valve and butterfly valve
Q:Why is copper used in cryogenic valves?
Contact with water does not corrode easily。he influence of temperature on copper is smaller than that of steel. Especially in the valve stem, there is also the important gear part, copper!
Q:How can the material be checked by valve approach? What experiments do you need?
First of all, to check material certification, and secondly, the material appearance, shape and size of the initial test, again on the alloy material according to the standard spectrum analysis, the valve to do pressure test.
Q:What do you mean by "P54" in the valve z962y-p54 100V?
P54 is the body temperature, heavy rain or equal to 545 degrees, 100V is 10Mpa, that is 100 kilogramsThere are all the valves on the nameplate
Q:What are the specifications of the valves PN25, DN50?
Upstairs professional level can be seen very solid.... Clap your hands... Popular speaking, that is, the valve bore is 50, resistance to pressure is below 25, is no problem.
Q:Valve legend
F means a pressure gauge or thermometer; as to which type of valve, the marking should be a stop valve.
Q:How can the valve actuators be classified?
Various types of valves, with the continuous improvement of various types of equipment, process, the types of valves are still increasing. But generally speaking, they can be divided into two major groups.(1) automatic valve. A valve that moves by itself depending on the capacity of a medium (liquid, air, steam, etc.). Such as safety valve, pressure reducing valve, check valve, steam trap, air trap, emergency shut-off valve and so on. (2) drive valve. A valve operated by hand, power, hydraulic, or pneumatic. Such as gate valve, globe valve, throttle valve, regulating valve, butterfly valve, ball valve, plug valve and so on.
Q:Symbols for all types of valves
Look at the attachment I gave you. The legend of the valves is complete!
