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: What is the choice of pneumatic valve or electric valve for ultrafiltration inlet control valve?
- The difference between the three is as follows: pneumatic valve]: driven by compressed air valve. Operation principle: the pneumatic control valve is composed of actuating mechanism and regulating mechanism. The actuating mechanism is a thrust component of the regulating valve, which generates the corresponding thrust according to the pressure of the control signal, and drives the regulating mechanism to move. The valve body is the regulating component of the pneumatic control valve. It contacts the regulating medium directly and regulates the flow of the fluid. [hydraulic valve]: the use of oil and other liquid pressure driven valve. The working principle of the hydraulic valve control valve pressure control valve flow control valve control valve control valve to control the direction of hydraulic system oil flow direction or liquid flow through the valve two, the working principle of the valve core and the valve body and valve off valve two-way hydraulic lock check valve to make oil movement off or on, changing the direction of the oil flow, so as to realize the hydraulic actuator and its driving mechanism of starting and stopping or changing the direction of movement. [electric valve]: with electric actuators to control the valve, so as to achieve the valve opening and closing. The utility model can be divided into two parts, the upper part of which is an electric executor, and the lower half of which is a valve. Also called air conditioning valve. The electric valve is usually connected by the electric actuator and the valve, and it becomes an electric valve after installation and debugging. The electric valve uses the electric energy as the power to switch on the electric actuator to drive the valve and realize the valve switching and regulating action. So as to achieve the purpose of switching or regulating the pipeline medium.
- Q: What is the difference between the valve before the pump and the valve after the pump?
- Pump front valve: current limit; pump rear valve: limit pressure.Pump operating procedures: the pump must be closed before and after the valve, open the pump, slowly open the pump front valve, pump pressure normal, slowly open the pump, valve until all open. If the pump is in front and rear valves are opened, the pump is very easy to burn the motor.
- Q: The expert can tell me how to install this valve, and what fittings to use on both sides
- If the process permits, you can first weld on both sides of the flange, modified into a flange butterfly valve, and then installed on the pipe, easy to overhaul later
- Q: 1) the valve plate, valve gate valve, the difference (my personal understanding is that if it is on the ball, called the valve, if the valve is called the gate, is actually a meaning in different valve called, please help me understand it right?)2) valve clack. What's the spool?3) the valve seat is welded inside the valve, or is it directly installed inside without welding?4) when opening the valve, if the valve seat is not welded, then, under the pressure of the medium, why not open the seat?.5) excuse me, pressure self sealing (my personal understanding is that when the valve is closed, the valve plate and valve seat depend on the pressure of the media, and they fit together to seal the effect
- The first question is basically the same, and you can understand that for the secondThe 3,4 problem, there are several seat connections, such as thread connection (threaded, the valve seat is connected with the valve), modular connection (such as adding the cage to a fixed seat, the crushed) as one of the body and there is (some welding). The valve seat must be fixed.The fifth question, you are right!
- Q: What are the valve types H, F, and Y? What are the meanings of these 3 letters?
- Please refer to "JB/T308-2004 valve model preparation method"Sealing surface material codeH Cr13 stainless steelF fluoroplasticY cemented carbide
- Q: Which valve can play a good regulatory role?
- A wide range of valves, the function is different, although like conventional butterfly valve, ball valve can play a regulatory role, but their role is not linear, so if you need to adjust the precision of the valve, it is best to select the control valve.
- Q: How big valves are used in the DN90 pipeline?
- If you use a 97 tube, the inner diameter of 89- phi 90., nominal pressure is low, then try to use DN80, DN80 valve diameter of 80, you can try butt welding
- Q: What are the ten major brands of China's valves?
- Tianjin Gangyan guangheng special equipment Limited by Share Ltd is the leader Chinese special material valve industry, a joint venture with Chinese Gangyan established
- Q: There is a rectangular hole in the valve core, which the heating company repairman gives to the bolt. Rest assured, I do not want to heating, but my indoor temperature is low, I suspect that the repairman mischief, deliberately give me lower temperature
- The valve has a device like a cylinder lock that opens with a special key.The heating valve refers only to a radiator system accessories, is a type of valve, the valve commonly used heating system on the market is mainly divided into: gate valve, ball valve, safety valve, balance valve, globe valve, regulator valve, relief valve, pneumatic control valve.
- Q: Why is the valve on the pipeline not the same size as the pipe, and how much of a crude pipe can be given? Thank youI'm sorry, I didn't make it clear that when doing pipe work in the factory, for example, 60 of the pipe, and in this pipeline to install the valve to choose DN50, and so on.
- The pipe you choose is outside the 60 bar D60 pipe DN50 valve is right, such as D89 pipe with DN80, you are outside diameter and nominal diameter concept is not clear
