Orbit 57257 Four-Valve Preassembled Manifold
Orbit 57257 Four-Valve Preassembled Manifold for a new four-zone wired valve bank with room for a preassembled layout.
Choose this model for a new four-zone wired valve bank with room for a preassembled layout.
- Good for
- A new four-zone wired valve bank with room for a preassembled layout.
- Look elsewhere if
- You need one valve repair or a layout with different valve spacing.
- The tradeoff
- Preassembly simplifies the valve bank but fixes much of its physical arrangement.
At a glance
- Solenoid Voltage
- 24-vac
- Pipe Connection
- three-quarter-socket
- Valve Format
- four-valve-manifold
Why it earns a look
- Four valves arrive in one coordinated assembly.
- Swivel unions support servicing and reconfiguration.
Where it asks for a compromise
- It still needs compatible wiring, piping and a suitable installation area.
Leave room to service the finished manifold
A neat valve bank is useful only if the box leaves enough room for its lids, unions and wiring. Check the pipe route before choosing preassembly. For one failed valve, a single replacement is usually a more focused purchase than rebuilding the entire bank.
Living with it in the garden
Check connections for leaks after installation.
Keep serviceable seals and fittings accessible.
