High-quality Water Supply Gate Valves for Sale | WEIZIDOM

2025.11.07

In urban water supply networks, industrial cooling water systems, sewage treatment, and fire protection systems, gate valves are core control devices ensuring the safe and stable transport of fluids. High-quality water supply gate valves not only achieve effective opening and closing control but also prevent water waste, insufficient system pressure, and equipment damage caused by media leakage. Therefore, selecting suitable and reliable gate valves for water supply systems is an extremely important task in the engineering design and procurement process.

I. Structural Advantages and Performance Characteristics of Water Supply Gate Valves

Our recommended gate valves for water supply systems primarily feature ductile iron valve bodies and soft-seal structures. They are particularly suitable for water supply systems operating continuously for extended periods and offer the following core advantages:

Performance AdvantagesDescription
Zero Leakage DesignEPDM rubber-coated valve plate ensures a stable seal
Low Flow ResistanceFull-bore design guarantees smooth water flow and improves delivery efficiency
Strong Corrosion Resistance≥250μm epoxy resin coating inside and out prevents rust and water pollution
Flexible Installation EnvironmentAvailable in exposed or concealed stem structures, suitable for above-ground or underground installation

Low Maintenance Costs | Simple structure, easy opening and closing, requires minimal maintenance for long-term use.

II. Applicable Scenarios and Application Value

Application AreasRecommendation ReasonsProblems Solved
Municipal Water Supply NetworksReliable sealing, long service lifeReduces leakage rate, stabilizes urban water pressure
Industrial Circulating Water SystemsSuperior corrosion resistanceAdaptable to long-term operation with various water media
Fire Protection Water Supply SystemsRapid opening and closing, high pressure resistanceEnsure reliable startup in emergency situations
Water plants and pumping stationsFlexible installation is possibleMeets the flow scheduling requirements of large-scale pipeline networks

III. How to select the right water supply gate valve?

To avoid incorrect selection leading to increased rework and maintenance costs later, it is recommended to evaluate from the following five aspects:

  • 📌 Medium confirmation: such as drinking water, industrial water, containing particulate impurities, etc.
  • 📌 Pressure rating confirmation: common pressure ratings are PN10 / PN16 / PN25
  • 📌 Connection method selection: flange connection is the preferred choice for water supply systems, ensuring reliable sealing
  • 📌 Valve stem structure selection:
  • Ground installation → rising stem type for easy observation of opening
  • Underground manhole installation → concealed stem type to save space
  • 📌 Material selection: Recommended ductile iron valve body + EPDM seal, combining cost-effectiveness and durability
  • 📌 Engineering experience advice: If used for drinking water, please confirm that the valve coating and sealing materials meet drinking water hygiene requirements.

IV. Installation, Use, and Maintenance Recommendations

To ensure long-term reliable operation of the valve, please note the following points:

  • 1) Clean impurities from the pipes and valve cavity before installation to avoid scratching the sealing surface.
  • 2) Open and close the valve slowly to prevent water hammer impact.
  • 3) Perform valve opening and closing maintenance every 3–6 months to ensure flexibility.
  • 4) Keep the environment dry when installing in the manhole to prevent the valve stem from rusting and jamming.

V. Why Choose WEIZODOM?

👍 Experienced and Supported After-Sales: WEIZODOM has over 25 years of experience in production, export, and installation, ensuring reliable production and quality. We specialize in water supply valve manufacturing and technical solutions, and have a comprehensive after-sales service and technical guidance team.

👍 Safe and Reliable, Averting Danger: It is a "safety switch" that can immediately cut off water flow in the event of a sudden pipe burst, protecting your property from loss. Its superior sealing performance fundamentally eliminates leaks, saving every drop of precious water resources.

👍 Long lifespan, lower total cost of ownership: Although the initial investment is slightly higher, the ultra-long design life (up to decades) and "maintenance-free/minimum maintenance" characteristics will save you the procurement costs of frequent replacements and high maintenance and repair expenses. In the long run, its comprehensive economic benefits far exceed those of ordinary valves.

👍 Ensuring water quality and protecting health: The smooth, mirror-like inner wall and the protection of a non-toxic epoxy coating completely eliminate rust and yellow water, ensuring that the water delivered to the user's end is clear, safe, and reliable, especially suitable for drinking water systems with extremely high hygiene requirements.

👍 Highly efficient operation and energy saving: The streamlined flow channel design minimizes head loss, reducing the pump head requirements. For large-scale water supply systems, this translates to considerable energy savings over long-term operation.

👍 Wide applicability, addressing diverse challenges: Whether it's municipal main pipeline networks, building fire protection systems, industrial park circulating water, or agricultural irrigation and wastewater treatment projects, we can provide valve models and solutions matched to specific operating conditions.
