ECO FOOT Valve 300A/350A (with standard davit) – Product Overview

The ECO FOOT Valve is a ground-installed valve designed for large-bore pipelines where maintenance efficiency and stable suction performance are critical. Unlike conventional foot valves, its construction allows internal components to be serviced without complex disassembly, reducing downtime and lifecycle costs.

Key Engineering Advantages

• Ground type structure for stable installation

• Large bore compatibility (300A / 350A)

• Standard davit included for safe lifting and maintenance

• Designed for smooth priming performance

• Three connection ports for flexible piping layouts
  

Standard Specifications of ECO FOOT Valve (300A / 350A)

Specification	Detail
Maximum Working Pressure	1.0 MPa
Maximum Working Temperature	60°C
Connection Standard	JIS 10K Flange
Applicable Fluid	Liquid

Materials and Maintenance Design of ECO FOOT Valve

The ECO FOOT series is constructed using SCS13A / SUS304 stainless steel, ensuring corrosion resistance and durability in industrial environments.

Standard Sealing Materials

• Seat Packing / O-ring: EPDM

Optional Sealing Materials

For applications involving specialized fluids, the following options are available:

• Silicone

• Fluorine rubber

• PTFE

Fluid compatibility must be confirmed based on fluid type, concentration, and operating temperature to ensure proper material selection.

A major design advantage of the ECO FOOT Valve is the replaceable seat packing and O-ring, enabling routine maintenance without replacing the entire valve assembly.

ECO FOOT Valve Dimensions (Model 10FAF-1-04)

Model	Size	L1 (mm)	L2 (mm)	H (mm)	Remarks
10FAF-1-04	300A (12")	400	415	750	Standard Davit Included
10FAF-1-04	350A (14")	480	480	1100	Standard Davit Included

For sizes above 350A, including 400A and 450A, a standard davit is also provided, with double valve elements applied in certain configurations. Consultation is recommended for 450A and above.
