Are there safety valves that allow the unloading pressure to be adjusted remotely?
Thread Content
Dear sea friends: Is there any safety valve that can have its discharge pressure remotely set and adjusted via an industrial computer or PLC? There is a project that requires high-pressure single-channel nitrogen output, with the desired output pressures being 16 MPa, 21 MPa, 35 MPa, 45 MPa, and 70 MPa. Safety valves need to be installed at the end of this pipeline for each of these output pressures; of course, these valves must be controllable remotely. How can this be achieved? Thank you! :curse:
The user wants a safety valve to quickly release pressure in emergency situations, rather than using a pressure regulator
First of all, a safety valve is designed to protect the equipment, not to control pressure. To control pressure, use a control valve; the SIS system can also be used to release pressure quickly.
High-altitude venting, with a combined control valve and silencer.
