Dwyer GVS Series Piston Globe Valve Switch offer accurate flow detection with 1% repeatability and external adjustability over a broad range of flow settings for compatible liquids.
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 GVS Series Features
- Externally adjustable flow set point
- Durable construction delivers long-life reliability in either water or oil
- Ample space for flow to pass keep pressure drop low
- Detection of improper flow rates in high volume lubrication
- Low flow detection in cooling lines
- Flow detection in process systems
