Reliable, heavy‑duty 1" inline hydraulic valve from Toro's 250 Series—designed for irrigation and light commercial systems. The 250-01-04 is a normally open (N/O) globe‑style valve with an integrated manual flow control handle for on‑site tuning and an external manual bleed for accurate shutoff. Engineered for debris resistance and long service life, it balances precise control with easy maintenance.

  • Durable construction: Glass‑filled Zytel body and bonnet for corrosion resistance and long life.
  • Flow control: Adjustable manual flow‑control handle lets you regulate flow down to zero for balancing and testing.
  • Reliable operation: Single‑piece rubber diaphragm and self‑cleaning stainless steel metering pin for consistent performance.
  • Serviceable design: External manual bleed and serviceable bonnet speed maintenance without system removal.
  • Ports & connections: 1" female x female (FxF) pipe threads—inline globe‑style porting for standard irrigation piping.
  • Performance range: Rated for typical irrigation pressures; 1" size recommended flow range ≈ 5–30 GPM and operating pressure range ≈ 20–150 PSI.

Install this valve in irrigation zones where adjustable flow and dependable shutoff are required. The 250 Series is compatible with hydraulic and many electric control configurations; consult Toro documentation for solenoid options and wiring when converting to electric control. Routine maintenance—periodic inspection for debris and occasional bonnet service—keeps performance reliable. See the 252 Series sell sheet and Toro parts documents for exploded diagrams, service parts, and ordering information.
