The solenoid valve of the water-cooled system freezer is used for the switching control of liquid and gas pipelines. It is a two-DO control and is generally used for the control of small pipes. The electric valve is an analog adjustment for the flow of the medium in the liquid, gas and wind systems and is an AI control. In the control of large valves and wind systems, electric valves can also be used for two-position switch control.
Need to pay attention to the solenoid valve can only be used as a switch, it is DO control, can only be used for small pipe control, common in DN50 and below pipes, it is rare. The electric valve can have an AI feedback signal and can be controlled by DO or AO, which is more common in large pipes and dampers.
The solenoid valve of the water-cooled system freezer is driven by the coil and can only be turned on or off, and the operation time is short when switching. The drive of the electric valve is generally a motor, and the opening or closing action requires a certain amount of time for the analog quantity, and can be adjusted.
The water-cooling system freezer solenoid valve generally has a small flow coefficient and a small difference in working pressure. For example, a general 25-caliber solenoid valve has a smaller flow coefficient than a 15-caliber electric ball valve. The solenoid valve is driven by an electromagnetic coil and is relatively easily damaged by voltage surges. Equivalent to the role of the switch, is the role of opening and closing. The electric valve is generally driven by a motor and is more resistant to voltage surges. The solenoid valve is fast open and fast closed. It is generally used in small flow and small pressure, and the electric switch is required in the place where the switching frequency is large. The opening of the electric valve can be controlled. The state has open, closed, half open and half closed, which can control the flow of the medium in the pipeline and the solenoid valve can not meet this requirement. The solenoid valve can be reset by general power failure, and the electric valve needs to be reset by such a function.
Water-cooled system freezer solenoid valve is suitable for some special process requirements, such as leakage, fluid medium special, etc., the price is more expensive, and the electric valve is generally used for adjustment, but also has a switch quantity, such as: fan coil end.
We offer EVR/MSV two types refrigeration solenoid valves of various sizes, and ensure normal operation at -40℃. In addition, we also have refrigeration solenoid valves for ammonia refrigerant.
