Product Introduction

Product Overview

The Foot Valve Strainer Stainless Steel features a heavy-duty design engineered for reliable pump suction line protection. This specific configuration utilizes a high-strength ductile iron housing paired with a heavy-gauge, full stainless steel 304 strainer and internal trim.

It combines the superior economy and pressure resistance of ductile iron with the exceptional corrosion resistance of stainless steel filtration components.

Why Leading Distributors Choose Our Foot Valves

Features an open area ratio over 3:1 to maximize fluid intake and prevent pump cavitation.

Hydrostatically tested to API 598 or EN 12266-1 standards before coating for zero-leakage backflow isolation.

Combines a PN25-rated ductile iron body with stainless steel internals, cutting alloy costs while maintaining high pressure limits.

Machined precisely to ANSI, DIN, or BS bolt patterns for seamless international piping compatibility.

A 250-micron fusion-bonded epoxy coating pairs with the stainless steel mesh for complete corrosion protection.

Technical Features & Performance Curve

Low Cracking Pressure

Springs are calibrated to ensure the valve opens fully even under low suction heads, reducing pump workload.

Streamlined Flow Body

The internal globe-style geometry minimizes turbulence and fluid resistance.

Applications / Industry Served

Water Treatment & Distribution Plants

Industrial Process Water & Sewage Handling

Agricultural Irrigation & Drainage Systems

HVAC Cooling Tower Feed Lines

Warranty & Value-Added Services

18-Month Warranty

We provide an 18-month warranty from the shipping date or 12 months from the installation date against manufacturing defects.

OEM/ODM Service

Free logo casting on the valve body for distributor orders exceeding 100 pieces.

3D Files Available

We provide STEP/AutoCAD files upon request for project bidding and piping system design.

Installation, Operation & Maintenance (IOM) Highlights

Vertical Installation

Must be installed strictly in a vertical position at the lowest point of the pump suction line.

Submergence Depth

Ensure the strainer is submerged at a depth of at least 3 to 4 times the pipe diameter to prevent vortexing.

Easy Clean-out

The SS304 strainer basket can be easily detached by removing the bottom bolts for routine debris cleaning.

FAQ

Q: Why is it named "Stainless Steel" if the body is Ductile Iron?

A: The name refers to the standard-equipped SS304 filtration basket and internal trim (stem/spring). For large sizes (2"-12"), a ductile iron body offers the best balance of high pressure resistance and cost efficiency.

Q: Do you provide Material Test Reports (MTRs) for both iron and stainless steel?

A: Yes. Every shipment includes EN 10204 3.1 MTRs certifying the chemical and mechanical properties of the QT450-10 iron body and SS304 strainer.

Q: Is every single valve pressure tested before shipment?

A: Yes. We perform 100% hydrostatic shell and seat testing per API 598 or EN 12266-1 standards to ensure zero leakage.

Q: What is your standard lead time for bulk container orders?

A: 25–30 days for a full 20ft container. Batch samples or stock items can ship within 7–10 days.

Q: Can you customize the strainer mesh hole sizes?

A: Yes. We can customize the stainless steel perforated hole sizes from 2mm to 6mm to suit your specific fluid and project requirements.
