Understanding the PI123 Valve

Whether it’s for manufacturing, petrochemicals, or oil and gas, the PI123 Valve (or Pressure-Indicator Controller Valve) is an indispensable piece of equipment. Controlling pressure and monitoring critical parameters, is vital in guaranteeing the reliability of a wide range of processes.

Design and Components

It boasts a robust and reliable design, consisting of several key components:

  • Body: The valve body is typically constructed from high-quality materials such as stainless steel or brass, ensuring durability and resistance to corrosion.
  • Actuator: This component controls the valve’s opening and closing, allowing precise pressure adjustments.
  • Sensors: Pressure sensors are integrated into the valve to monitor pressure levels continually.
  • Controller: The valve’s controller interprets sensor data and manages the valve’s operation to maintain the desired pressure setpoints.


This is used primarily to control the pressure of a fluid or gas within a system. This is achieved by the controller’s modifications to the actuator and information from the pressure sensors. To keep everything running smoothly and safely, the valve will take action if the pressure drops below the setpoint.


The versatility of the PI123 Valve makes it a valuable asset in various industries. Below are some of its key applications:

1. Manufacturing

To guarantee the reliability of manufactured goods, precise pressure regulation is essential during production. Pressure in hydraulic systems, pneumatic systems, and injection molding machines can all be controlled with this.

2. Petrochemical Industry
