Price of marine hydraulic butterfly valve with feedback

The principle of the balance valve is the anti-regulation in the valve body. When the pressure at the inlet increases, the diameter is automatically reduced to reduce the change of flow, and vice versa. If the connection is reversed, this adjustment system will not work. Moreover, the regulating valve is directional, and the reverse pressure can even reduce or even close the flow. Since the balance valve is installed for better heating, there is no problem of reverse installation. If it is a reverse installation, it is a human error, and of course it will be corrected. Balance valve belongs to the category of regulating valve. Its working principle is to change the flow resistance of fluid flowing through the valve by changing the gap between the valve core and the valve seat (that is, the opening) to achieve the purpose of adjusting the flow rate. The balance valve is equivalent to a throttling element whose local resistance can be changed. For incompressible fluids, it can be obtained by the flow equation.

The factory specializes in providing marine butterfly valves, marine gate valves, marine check valves, marine regulating valves, marine pressure reducing valves, marine breathing valves, high-speed vent valves, marine quick-closing valves, marine self-closing valves, marine cock valves, marine fire-fighting valves, Marine sea valve, marine wave valve, marine filter, marine air pipe head, marine ball valve, marine stop valve, marine stop check valve and other valves. The handle should be turned back and forth to ensure the correct combination of turbine and turbine. The premise is that the actuator has been fully assembled and reliably connected, all bolts have been fully tightened, the operating conditions and limit values ​​are checked, the hydraulic power supply is turned on, and the operation is under lower pressure. When using an additional throttle valve, first check whether the function is normal at low speed. The valve closing limit regulator and the valve opening limit regulator are used as the switching point of the regulating valve. When our company provides a complete set of marine valves and hydraulic actuators, the switch address has been adjusted before leaving the factory. If there is no accident, the buyer does not need to adjust. In special circumstances, suppose that the maintenance, installation and commissioning of the actuator are only purchased by you. Such as oxygen, methane, ethylene, etc., are widely used in various industries.

It is convenient for remote control; 6) It is convenient to maintain. The sealing ring is generally movable and easy to disassemble and replace; 7) When fully open or fully closed, the sealing surface of the ball and valve seat is isolated from the medium, and the medium will not cause Erosion of the valve sealing surface.

　　The balance valve is a regulating valve with a special function of digital locking. It adopts a direct-flow valve body structure and has a better equal percentage flow characteristic. It can distribute the flow reasonably and effectively solve the room temperature in the heating ( air conditioning ) system. Uneven hot and cold problems. At the same time, it can accurately adjust the pressure drop and flow rate to improve the liquid flow state in the pipe network system to achieve the purpose of liquid balance in the pipe network and energy saving.

Chinese name hard-seal ball valve attribute valve classification one-way seal, 1) One-way seal: only seal in the specified direction, that is, the sealing direction marked by the ball valve. 2) Two-way sealing: It can be sealed in both directions.

　　Indicates the valve opening degree is provided, the opening degree of the lock given load and means for measuring small flow valve, the locking as long as the user after each branch and the inlet of the balancing valve fitted with the appropriate size, and with special debugging disposable smart meter, The total water volume of the system is controlled within a reasonable range, thereby overcoming the unreasonable phenomenon of “large flow, small temperature difference”.
