MHA Balance Valve
MHA balance valve is a valve used to regulate the flow rate and pressure of fluids (such as hydraulic oil), and is widely used in hydraulic systems, industrial equipment, engineering machinery and other fields. The following is an introduction from the aspects of product characteristics, working principles, application scenarios, technical parameters and purchasing suggestions:
1. Product Features
The high-precision control MHA balance valve adopts advanced flow control technology, which can achieve high-precision adjustment of fluid flow and ensure stable operation of the system.
The flow adjustment range is wide, suitable for high flow and low flow conditions, meeting the needs of different working conditions.
Strong stability is made of high-quality materials and advanced processes, with excellent durability and stability, and can maintain stable performance even in harsh working environments.
The sealing performance is reliable and is sealed with polytetrafluoroethylene and silicone to effectively prevent leakage.
Easy to install and maintain modular design, easy to install, compact structure, easy to disassemble and repair, reducing maintenance costs and time.
The internal components are made of YICr18Ni9 or copper alloy, which has strong corrosion resistance and long service life.
It has various functions and has a cutoff function, and there is no need to install an additional shutoff valve after installation.
There is a reliable opening lock memory device, and the valve opening can be restored to its original locked position after changing.
Provides accurate valve opening indication with a minimum reading of 1% of the full valve opening.
2. Working principle
The MHA balance valve controls the flow rate by changing the gap between the valve spool and the valve seat (i.e., the opening degree) to adjust the flow resistance of the fluid flowing through the valve. Its working principle is based on the following formula:
Q=ξ⋅ρ2⋅ΔP
Q: The flow rate through the balance valve
ξ: The resistance coefficient of the balance valve
ΔP: Front and rear pressure drop of valve
ρ: The density of the fluid
When the front and rear pressure drop (ΔP) of the valve remains unchanged, the flow rate (Q) is only affected by the resistance coefficient (ξ) of the balance valve. By adjusting the valve core opening and changing the resistance coefficient, precise control of flow is achieved.
III. Application scenarios
The hydraulic system is used to adjust the speed of the hydraulic cylinder or hydraulic motor to ensure the smooth operation of the system.
It is widely used in engineering machinery, metallurgical equipment, injection molding machines and other fields.
Industrial equipment is used to control fluid flow and pressure to meet different process needs.
Play an important role in petrochemical, electricity, metallurgy and other industries.
Construction machinery is used in hydraulic systems for excavators, cranes and other equipment to improve operating accuracy and efficiency.
An automated production line is used to control the speed of actuators such as conveyor belts and robots to achieve precise control.
