Key Specifications

Based on the labeling and visual features:

  • Material: UPVC (Unplasticized Polyvinyl Chloride), which is highly resistant to corrosion and chemical damage.

  • Type: True Union. This design allows the central body of the valve to be removed from the pipeline for maintenance or repair without having to cut the pipe.

  • Size: 3″ (DN80 nominal diameter).

  • Pressure Rating: 150 PSI at 15°C.

  • Temperature Limit: Maximum 55°C.

  • Handle: Large red T-handle for manual “Quarter-Turn” operation (On/Off).

Design Features

  • Connection Points: The ends feature socket-style unions, likely for solvent cement welding to standard 3-inch PVC pipes.

  • Mounting Pad: There is a molded integrated mounting pad (visible just below the handle) which can be used to secure the valve to a bracket or to mount an automated actuator.

  • Color Scheme: Dark grey body with a high-visibility red handle, typical for industrial-grade plastic valves.


Common Applications

These valves are standard in environments where metal valves might corrode or where cost-effective, high-flow control is needed, such as:

  • Water treatment and swimming pool filtration systems.

  • Chemical processing and irrigation.

  • Aquaculture and large-scale aquarium life support.
