The valve limits the flow rate in the pipeline to a preset rate, regardless of upstream pressure variations. The valve is controlled by pilot valve, which takes use of integrated orifice plate to detect flow rate represented by differential pressure, and the differential pressure is used to control the pilot valve to implement flow rate control.
     The 400X flow control valve is a multifunctional valve that adopts the mode of flow control employed by high-precision pilot valve. It is suitable for use in water distribution pipes within which the flow and pressure need to be controlled, and can serve to keep thepreset flow constant, restrict excessive flow at a preset value and reduce the excessively high pressure upstream properly. This valve differs from other conventional throttle valve, which normally work through reducing the flow area bymeans of orifice plates or purely mechanically,by making use of an appropriate pilot valve to minimize the loss of energy in the course of flow regulation. The 400X flow control valve can completely stop the flow in case of an emergency to avoid loss. Accordingly, it boasts high control sensitivity and isreliable, safe,simple to debug and offers a long service life. Pressure Rating: PN10. PN16. PN25/Class150Size Range:

Q:What's the name of the valve?
This is the discharge valve, the lower part of the handle protruding part of the valve is the sealing device. The overall material should be brass, which is typically made by equipment manufacturers.
Q:What is the diameter of a general pipe valve?
In fact, the essence of the problem is the corresponding relationship between the nominal diameter and other dimensioning methods. Valves are generally marked with nominal diameter (DN***), such as DN150, DN100 and so on. There are many kinds of marking methods for pipes, such as outer diameter, inch inch, nominal diameter, etc.. Only when the other dimensioning is converted to nominal diameter, the valve and the pipe correspond to each other.
Q:How do I open the gas valve?
1, the natural gas valve "Shun" pipeline is open, "horizontal" as "off". The following is to open the valve diagram Turn left and turn right | 2. Attachment: the function of the main facilities of natural gas is:Valve well: a device for installing a valve to control an underground gas pipeline. The building regulation boxes or regional station: the device will be adjusted to the user requirements of medium pressure natural gas pressure. The riser valve: General in the first floor of the building, the kitchen are arranged on the pipe, the vertical pipe used to control all users. Indoor main valve: also known as meter front valve, is the home gas main switch, placed in front of the gas meter, used for natural gas on-off. This valve "opens" the pipe to be opened, "cross" is the pass. Gas meter: IC card intelligent gas meter and user gas consumption measuring device. The front of the stove valve: located in the table, the control valve of gas stove, gas should be closed after the end of time. The IC card is convenient for users to purchase gas use.
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:What does the RF of the valve mean?
Convex flange, RAISED, FACE,At 150#, 300#, height is 2MMAbove is 7MM,
Q:In the fire drawing, what valve does the following valve represent?
Are you in the sprinkler system? Signal valve and alarm valve
Q:What are the definitions of internal, external and leakage valves?
The leakage within the valve that is the reason of erosion wear medium makes the valve is not closed tightly, even if the valve screw (stem) screwed in place, because there is still a gap between the spool and the valve body, the medium can flow past.
Q:What is the term "Z41H-16C" on the line?
Therefore, the opening position of the valve is determined by the position of the gate (i.e. the stroke).Z41H-16C closed, the sealing surface can only rely on medium pressure to seal, that is, only rely on the media pressure to the gate sealing surface pressure to the other side of the seat to ensure the sealing surface seal, which is self sealing. Most of the valve is forced seal, that is, when the valve closes, to rely on external force to force the gate to the seat, in order to ensure the sealing surface sealing.
Q:Internal structure of valve
To answer your question was the top valve is not open on the thread of an analogy between ordinary wood screws and nails is a straight out of another can only rely on the screwdriver to turn out the cut-off valve is from the mechanical analysis of text as a specific principle is not specific
Q:How to carry out the valve strength test and air tightness test?
All the factory must go through the valve pressure test, strength test for 1.5 times the nominal pressure, closed at both ends of the valve import and export, fully open the valve test pressure for 1 - 5 minutes, see the specific situation, also called low pressure seal test seal test pressure seal test, 0.6MPa. Also 1.1 times the seal hydrostatic test, specific, you see, JB/T9092 standard, very detailed
