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.

Dwyer Series P8 Piston High Pressure Brass Flow Switch

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
