Superior 3300 Master Valve — Brass, Normally Open, FIPT x FIPT

The Superior 3300 Master Valve is a brass, normally open irrigation master valve designed for reliable service with dirty or recycled water. Dual-chamber control removes minimum-flow constraints so the valve opens and closes reliably at any system flow rate. External plumbing gives easy access to the filter assembly for fast maintenance, and reclaimed-water handle upgrades are available.

• Construction and connection: Solid brass body with FIPT x FIPT threaded connections; BSPT threads available on request for international installations.
• Sizes and models: Available in 1 1/2", 2", 2 1/2" and 3" models (3300150, 3300200, 3300250, 3300300). Add RW to model number for a purple reclaimed-water handle.
• Flow and pressure: Operates across a wide range — 0 to 320 GPM flow capacity and 20 to 200 PSI working pressure for commercial and large-residential irrigation systems.
• Dual-chamber performance: Dual-chamber design provides true no-minimum-flow capability and stable operation even at very low or fluctuating flows.
• Diaphragm and reliability: 600 lb. test nylon-reinforced EPDM diaphragm resists wear from debris and recycled water, extending service life in demanding conditions.
• Solenoid and power: Standard 24 VAC solenoid (in-rush 0.45 A, holding 0.30 A; 10.8/7.2 VA). Optional 110 VAC solenoid is available (in-rush 95 mA, holding 65 mA).

Use the Superior 3300 as a robust master or mainline valve where dependable pressurization, on-demand manual access, and easy filter maintenance matter. Its reclaimed-water option, heavy-duty diaphragm, and broad operating ranges make it ideal for commercial landscapes, parks, and systems using recycled water.
