Irrigation filters, valves, controllers and fittings
Irrigation valves and fittings: size and pressure
Confirm actual size, connection standard, pressure and function before ordering irrigation valves and fittings.
When to use this reference
Use this reference when inch designations are treated as measured diameter or threaded, compression and flanged connections look equivalent in photos. The goal is to separate confirmed project facts from commercial assumptions before comparing models or requesting a quotation.
Technical checks
Identify pipe material and outside/inside diameter, thread or flange standard and pitch, pressure class, flow, valve function and chemical compatibility. Record the source of every value and treat missing data as pending, never as a confirmed default.
- Photograph a ruler beside the connection.
- Copy PN, DN and flow-arrow markings.
- Confirm PE, PVC or metal pipe.
- List required adapters and sealing method.
