What is the difference between low-temperature butterfly valves and low-temperature instrument butterfly valves?
Thread Content
For a recent tender, the client requested low-temperature instrument butterfly valves and low-temperature instrument ball valves. I’m not familiar with this area – what are the differences in function and structure between low-temperature instrument butterfly valves and ordinary low-temperature butterfly valves, as well as between low-temperature instrument ball valves and ordinary low-temperature ball valves? ? Thank you, boss
Instrument valves have control features for regulating parameters such as flow rate, pressure, or other operating conditions of the medium. A general valve refers to a process valve that performs opening and closing actions. The two have different requirements in terms of action implementation, and their structures also differ.
The instrument valves are all valves with remote control, while ordinary valves are operated manually. The driving methods of the two are different. It’s to check whether there are control cables or air supply lines

Difference between with remote control and without remote control
Low-temperature instrument ball valves are generally designed to be quite delicate, with small sizes and high adjustment precision
For low temperatures, it is necessary to use materials suitable for low temperatures in manufacturing; furthermore, the connection between the actuator and the valve body needs to be extended.
