LPI11 Self regulating Pressure Control Valve, Pressure Control Valve (PCV), Pressure Regulating Valve (PRV)
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:
- Can be upstream control or downstream control.
- No external energy, automatic adjustment.
- Simplifying equipment, energy conservation.
- Compact structure, fewer parts, light weight.
- Easy to install and operate.
- Regulating performance, accurate flow coefficient.
