Ductile Iron Body 100X Pilot-Operated Float Valve
Product Introduction
The Ductile Iron Body 100X Pilot-Operated Float Valve is a hydraulic self-actuated valve for automatic liquid level control. Featuring a ductile iron body (GGG40/ASTM A536), brass trim, and elastomer seals, it utilizes float linkage to manage water levels in tanks/reservoirs without external power. Ideal for municipal water supply, firewater storage, and industrial circulation systems, it operates at 0℃to 80℃with PN10/ANSI 125 pressure, compatible with horizontal/vertical piping.
Product Advantages
- Energy-Saving Operation: Zero power consumption; adjustable float sensitivity (±5cm level difference) adapts to varied tank sizes.
- Versatile Installation: Side/top mount options; flanges comply with GB/T 17241 for global pipeline compatibility.
- Cost Efficiency: Ductile iron and brass balance durability and affordability, ideal for mid-scale water facilities.
- Fail-Safe Design: Built-in strainer prevents debris blockage; no electronics ensure reliability in humid environments.
Product Features
Hydraulic Automation
100X pilot valve converts float movement into main valve actuation, ensuring precise inflow control and overflow prevention.
01
High Pressure Resistance
Ductile iron body withstands water hammer with ≥1.6MPa tensile strength, suitable for high-cycle operations.
02
Low-Flow Resistance
Full-bore design reduces head loss, increasing flow coefficient (Cv) by 20% for DN50-DN300 pipelines.
03
Durable Sealing
NBR or EPDM seats resist aging and compensate for wear, offering ≥5-year service life in clean water.
04
Tool-Free Maintenance
Modular float assembly allows seal replacement without draining the system.
