Where are High pressure valves used?
Application of these high pressure valves can be seen in the oil and gas production industry.
There are five various types of high pressure valves:

1. Relief: they act as the safeguard in fluid power systems by limiting the maximum pressure through diverting excess oil when the pressure is too high.
2. Reducing: when there is a downstream pressure in the hydraulic system, these high pressure valves remain open and closed. There are two types:
   direct acting
   operated by pilot
3. Sequence: they are used when the system or circuit has many actuators or cylinders that need pressure regulation and it has to be done sequentially. High pressure valves are helpful in such environments with the help of timers, limit switches, etc.
4. Counterbalance: they are used to set the pressure in a circuit to counterbalance any external force.
5. Unloading: as the name suggests, these high pressure valves are used in unloading pumps.
