Drinking Water
Valves for Drinking Water (Potable Water) Systems
The final barrier in the water cycle demands the highest standards. Valves in drinking water systems must be safe, hygienic, and compliant with stringent international standards for potable water.
Shield’s Commitment to Potable Water Safety:
-
Certified Materials: All wetted parts comply with NSF/ANSI 61, WRAS, and other global potable water standards, ensuring no contamination.
-
-
-
Full-Bore Ball Valves: Provide excellent seal integrity and minimal pressure drop for direct drinking water lines.
-
-
Hygienic Design: Surfaces and internal geometries that prevent bacterial growth and facilitate cleaning.
-
-
Corrosion-Resistant Construction: Available in bronze, brass, and stainless steel to maintain water purity over decades of service.
-
From treatment plant outlet to the point of use, Shield valves guarantee that the quality of water is preserved throughout the distribution journey.
Valves for Water & Watertreatment
Once treated, water travels through vast distribution networks to homes, businesses, and industries. Valves in these systems must manage pressure zones, isolate sections for maintenance, and prevent leaks.
Key Shield Products for Distribution Mains:
Resilient Seated Gate Valves: Provide bubble-tight sealing and low-torque operation for reliable isolation, even in dirty water conditions.
Tapping Valves: Allow for new service connections under pressure, minimizing supply disruption.
Air Release & Vacuum Valves: Crucial for maintaining system efficiency and preventing pipeline collapse by removing air pockets.
Pressure Reducing Valves (PRVs): Maintain safe, consistent pressure levels throughout the network, reducing leak rates and pipe stress.
Our distribution valves are engineered for underground or chamber installation, offering exceptional longevity with minimal maintenance needs.
Water treatment plants transform raw water from various sources into a safe, usable resource. This process involves multiple stages—coagulation, flocculation, sedimentation, filtration, and disinfection—each with specific flow control requirements.
Shield Valves provide robust solutions for these critical applications:
-
Gate Valves and Globe Valves: For reliable on/off service and flow throttling in pump discharge, chemical feed lines, and plant piping.
-
-
Check Valves: Prevent backflow, protecting pumps and equipment from damage. Our silent check valves minimize water hammer in high-capacity systems.
-
-
Butterfly Valves: Offer excellent shut-off and control for large diameter pipes in settling tanks, filter beds, and backwash lines. Liner and disc materials are selected for corrosion resistance.
-
-
Ball Valves: Provide tight shut-off for instrument air, chemical dosing, and auxiliary systems.
-
Our valves are constructed from materials compatible with potable water and treatment chemicals, ensuring longevity and system integrity.
Water Treatment Plants
SHIELD Solution for
A water treatment plant is a complex ecosystem of processes. Shield goes beyond supplying individual valves; we offer integrated Flow Control Solutions that enhance plant performance.
The Shield Advantage includes:

Overviews
Wastewater systems handle highly abrasive, corrosive, and solid-laden media. Valves must be exceptionally robust to prevent clogging, withstand hydrogen sulfide attack, and ensure reliable operation.
Shield Valves Built for the Toughest Duties:
Knife Gate Valves: Specifically designed to cut through and handle sludge, slurries, and wastewater with high suspended solids.
Dual Plate Check Valves: Compact, wear-resistant check valves for pump discharge, preventing reverse flow in sludge and sewage lines.
Non-Clogging Butterfly Valves: With special seat designs and disc profiles to prevent solids buildup, ideal for influent/effluent lines and aeration tanks.
Pinch Valves: Offer full-bore, unobstructed flow for raw sewage and abrasive slurries, with sleeves resistant to abrasion.
We select materials like stainless steel, duplex alloys, and specialized elastomers to combat the corrosive nature of wastewater.

Plunger (Needle) Control Valve
A plunger valve operates on a straightforward yet effective principle: a cylindrical or tapered plunger moves linearly within a valve body to open, close, or throttle a flow passage. Unlike rotary valves, this linear motion allows for precise stem positioning, making certain adjustable plunger valve designs excellent for applications requiring specific flow control.¥ 0.00Buy now
