The integrated filter and balancing valve save installation space and reduce installation costs.
At the same time, maintenance is more convenient.
FAQ
1. How fast does the electric operated ball valve respond?
The speed of the electric ball valve's response depends on the power of the actuator and the size of the valve, and the switching time is usually between 3 and 15 seconds. For larger-caliber ball valves, the response time may be longer.
2. Can the electric ball valve work under high temperature conditions?
Electric ball valves can work in high temperature environments, depending on the material and seals of the ball valve. Special high-temperature ball valves can withstand temperatures up to 400°C or more, but standard models are generally suitable for 0°C to 150°C.
3. Will the electric operated ball valve automatically close when the power is off?
Some electric ball valves have a power-off self-reset function, which automatically returns to the preset closed or open position when the power is off. But most standard electric ball valves will maintain their current switch state after power is off.
4. How to judge whether the electric operated ball valve is in the open or closed state?
Many electric ball valves are equipped with a position indicator that displays the current switch state of the valve. In addition, some models have a feedback signal that can feed back the switch state to the control system.
5. Can the electric ball valve be manually operated?
Most electric ball valves have a manual operation function, which can be used for switch control by manual operation when the electric actuator fails or the power fails.
