automatic stop valve
When the automatic stop valve is working, the thermostat provides a valve opening signal, which makes the driver connect to the AC power supply and start to open the valve, so that cold water or hot water enters the fan coil to provide cooling or heating for the room; when the room temperature reaches the set value of the thermostat, the thermostat cuts off the valve opening current, and the reset spring closes the valve, thereby cutting off the water flow into the fan coil. By closing and opening the valve, the room temperature is always kept within the temperature range set by the thermostat.

Features
High Installation Flexibility:
The electric actuator and valve body are designed separately, allowing for flexible installation. The actuator can be positioned in different ways to suit site conditions, making it adaptable to various working environments.
Convenient Maintenance:
With the actuator and valve body separated, maintenance can be performed on the actuator alone without disturbing the valve body. This reduces system downtime and maintenance costs, making the process more efficient and convenient.
Reduced Heat Accumulation:
The split design prevents direct contact between the actuator and valve body, which helps reduce heat buildup in the valve body during operation. This feature is especially beneficial in high-temperature or high-pressure conditions, improving the durability and stability of the valve.
FAQ
Q: What is it?
A: It is a type of valve that separates the electric actuator from the valve body, offering flexibility in installation and maintenance.
Q: What are the key benefits of using it?
A: It provides high installation flexibility, easier maintenance, and reduced heat accumulation, improving overall system performance and durability.
Q: How does it improve maintenance efficiency?
A: Since the actuator and valve body are separate, maintenance can be done independently on the actuator, minimizing downtime and maintenance costs.
Q: Is it suitable for high-temperature environments?
A: Yes, its split design helps prevent excessive heat buildup, making it ideal for high-temperature and high-pressure applications.
Q: Can it be installed in tight spaces?
A: Yes, because the actuator can be positioned independently from the valve body, it can be installed in tight or limited spaces, offering more installation flexibility.
