About remote control valve
Thread Content
In process production, we often see words such as remote control valve, such as HV1203. In actual production, why is it called a remote control valve? Is there anything different from a regulating valve? Please discuss.
My understanding is that HV-1203, for example, is actually a shut-off valve. It just installs a handwheel on the valve cylinder to facilitate manual operation and control by on-site operators in emergencies. This kind of valve is generally installed at critical process points.
The program-controlled valve we are talking about here is driven by a solenoid valve. According to the written program, the rapid switching valve that operates in time sequence is called a program-controlled valve.
HV-1203, in the design standards of the Ministry of Chemical Industry, "HV" generally uses a shut-off valve, which has no wiring when installed. The valve body has its own handwheel and can not form a loop control with any monitoring point. This type of valve is usually called a remote control valve. Most of these valves are used in fire safety interlock designs, and are also required for flare exhaust systems and some intermittent operations.
It refers to a two-position ball valve, which is controlled by DCS to open and close.
Generally, the regulating valve in the automatic regulating circuit is called an automatic regulating valve, and the regulating valve controlled by manual operation (through a hand operator, a button switch, etc.) is called a remote control valve.

The H here means "manual". The valve is manually controlled remotely. The operation method can be a switch, a hand operator, or a DCS. The valve can be a two-position on-off valve or a regulating valve.
Thank you for sharing. I finally understand the meaning of remote control valve.
