Dwyer Series GVS Piston Globe Valve Switch

Flow includes Flow Transmitters, Flow Sensors, Flowmeters, Sight Flow Indicators and Water Meters. Mass Flowmeters, Controllers, Flow Indicators and Controllers are ideal for measurement of flow rates. Flow Switches come as paddle, thermal, piezo, and shuttle/piston. Flow Switch Sensors with an electrical contact output at a specific flow rate have different types of switches, which are 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. The Series GVS Globe Valve Switches offer accurate flow detection with 1% repeatability and external adjustability over a broad range of flow settings for compatible liquids.

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

Application

• Detection of improper flow rates in high volume lubrication
• Low flow detection in cooling lines
• Flow detection in process systems
