Dear everyone, I would like to ask regarding salary increases for those in the HVAC field: \"The ventilation system in the liquid chlorine storage tank facility should be equipped with air valves that prevent air flow between the indoor and outdoor areas; the control switches for these valves should be easily operable from both inside and outside the facility.\" ” If the valve on site is a pneumatic valve, how can it be manually controlled to open and close on site? No handwheel needed.
Add a solenoid valve; the power switch for the solenoid valve can be installed indoors
The control switch for this air valve should be easily operable both indoors and outdoors
There are many such control methods; they can be installed both indoors and outdoors, and interlock control as well as other remote control options can be utilized. For reference.
How is it achieved with a solenoid valve? Could you tell me about it?
The solenoid valve signal is controlled by the switch in the control room; a logical OR operation is performed by the underlying program, allowing the solenoid valve to operate either in response to the signal from the control room or when the on-site button is pressed. If there is no control room, install a relay to control the power supply to the solenoid valve
