Dwyer Series P8 Piston High Pressure Brass Flow Switch

Dwyer Series P8 High-Pressure Brass Flow Switches are ideal for high in-line pressures. Set points range from 0.25 to 2.0 GPM for liquid flow.

Flow Switch Sensors with an electrical contact output at a specific flow rate have different types of switches, which are a paddle, thermal, piezo, and shuttle/piston.

Shuttle or piston flow switches are sensors with an electrical contact output at a specific flow rate. Models are used with oil, air, water, and gases. Applications include oil flow control, low flow detection in cooling lines, and high-pressure lubrication systems. Rugged construction and excellent chemical compatibility simplify flow/no flow detection.

Dwyer Series P8 Features

  • Integrates a one-piece magnetic PPS composite piston to handle pressure up to 1500 psi
  • Less susceptible to clogging than other high in-line pressure switches with 100-micron filtration

Application

  • Industrial cleaning equipment
  • High-pressure lubrication systems
