Feature

LPI11 self-operated pressure control valve is composed of control valve, actuator and spring used for pressure controlling, it is suitable for controlling downstream pressure in the pipes of non-corrosive liquids, gases and streams, when the downstream pressure sises, the control valve is closed.

The main features are as follows: 

  1. Can be upstream control or downstream control.
  2. No external energy, automatic adjustment.
  3. Simplifying equipment, energy conservation.
  4. Compact structure, fewer parts, light weight.
  5. Easy to install and operate.
  6. Regulating performance, accurate flow coefficient.
