Detailed Introduction:

Water & Wastewater Treatment:
Reliable Flow Control for Every Stage

Shield provides reliable valve solutions for municipal water supply, wastewater treatment, and industrial water systems. Our valves ensure corrosion resistance, tight sealing, and durability throughout intake, distribution, treatment, and discharge processes.

Potable Water Certified         Industrial Water         Wastewater Treatment        NSF/ANSI 61        WRAS Approved

Drinking Water Systems

Valves for potable water must be safe, hygienic, and compliant with international standards. Full-bore ball valves, resilient seated gate valves, and check valves provide bubble-tight sealing and minimal pressure drop.

Water Distribution Mains

Manage pressure zones, isolate sections for maintenance, and prevent leaks. Resilient seated gate valves, tapping valves, air release valves, and PRVs ensure system efficiency and longevity.

Wastewater Treatment

Handle abrasive slurries, corrosive media, and solids-laden flows with knife gate valves, non-clogging butterfly valves, dual plate check valves, and pinch valves built for the toughest duties.

Water Treatment Plants – Comprehensive Flow Control

Water treatment plants transform raw water into a safe resource through multiple stages: coagulation, flocculation, sedimentation, filtration, and disinfection. Shield provides robust solutions for these critical applications:

• Gate, Globe & Butterfly valves for pump discharge, chemical feed, and plant piping

• Silent check valves to prevent water hammer in high-capacity systems

• Lined butterfly valves with corrosion-resistant materials for filter beds and backwash lines

• Ball valves for instrument air, chemical dosing, and auxiliary systems

Certified for Water Safety

• NSF/ANSI 61 – Drinking Water System Components

• WRAS (Water Regulations Advisory Scheme)

• ISO 15848-1 low emissions

• API 607 Fire Safe

Built for the Toughest Duties – Wastewater & Sludge

Wastewater systems handle highly abrasive, corrosive, and solid-laden media. Valves must prevent clogging, withstand H₂S attack, and ensure reliable operation. Shield offers purpose-built solutions:

• Knife Gate Valves – Cut through sludge and slurries with high suspended solids

• Non‑Clogging Butterfly Valves – Special seat designs prevent solids buildup

• Dual Plate Check Valves – Compact, wear‑resistant for pump discharge

• Pinch Valves – Full-bore, unobstructed flow for raw sewage and abrasives

Shield Advantage

Materials selected include stainless steel, duplex alloys, and specialized elastomers to combat corrosion. Low maintenance design reduces downtime and lifecycle costs.
