Manual valves – operated by hand to control water flow.

Electric valves – controlled by electric signals from irrigation controllers, allowing automatic water management. Pressure-regulating valves – designed to maintain a consistent pressure, preventing overwatering or under-watering. Backflow preventer valves – used to prevent contaminated water from flowing back into the main water supply. Top manufacturers often focus on the durability of the valves, material quality (like brass, plastic, or stainless steel), and compatibility with different irrigation systems. They may offer products for agricultural, commercial, or residential use, with features such as weatherproofing, ease of installation, and long-lasting performance.
