In municipal wastewater treatment, industrial wastewater treatment, and reclaimed water reuse projects, valves are critical equipment for ensuring stable system operation, process control, and safety isolation. Due to the complex nature of wastewater media and varying operating conditions, improper valve selection often leads to leaks, blockages, corrosion failures, and even system shutdowns and significantly increased maintenance costs.
Therefore, more and more project owners and procurement personnel are focusing on "one-stop procurement solutions for wastewater treatment valves"—reducing project risks and improving overall efficiency through unified selection standards, centralized supply, and professional technical support. This article will systematically analyze the valve requirements of wastewater treatment projects and introduce the one-stop valve solution provided by WEIZIDOM.
Wastewater treatment systems typically encompass multiple stages, including influent, pretreatment, biological treatment, sedimentation, sludge treatment, and effluent reuse, placing higher demands on valves:
1. Corrosion Resistance
Wastewater often contains acids, alkalis, salts, and chemical agents, requiring valves with excellent corrosion resistance.
2. Wear Resistance and Anti-Clogging
Sewage and sludge contain a large number of suspended particles, requiring valve internal structures to prevent sedimentation, jamming, and rapid wear.
3. Reliable Sealing
Under frequent opening and closing and long-term operation conditions, valves must maintain stable sealing to prevent leakage.
4. Automation and Remote Control Capabilities
Modern wastewater treatment plants widely use automated control systems, requiring valves to support electric or pneumatic actuators.
1. Gate Valve
Application: Main pipelines, pump outlets, maintenance isolationAdvantages: Low flow resistance, stable performance in fully open and fully closed positions
Selection Recommendation: Use soft-sealed or corrosion-resistant materials, suitable for sewage and clean water pipelines
2. Butterfly Valve
Application: Large-diameter pipelines, regulating and isolation applications
Advantages: Compact structure, easy installation, high cost-effectiveness
Selection Recommendation: For sewage systems, prioritize rubber-lined or wear-resistant butterfly valves
3. Ball Valve
Application: Dosing systems, reclaimed water pipelines
Advantages: Good sealing performance, quick opening and closing
Selection Recommendation: Choose corrosion-resistant stainless steel or lined ball valves
4. Globe Valve and Control Valve
Application: Flow regulation, pressure control
Advantages: High adjustment accuracy, suitable for automated systems
Selection Recommendation: Use with electric or pneumatic actuators for precise control
5. Check Valve
Application: Pump outlets, preventing backflow of media
Advantages: Protects equipment, avoids water hammer impact
Selection Recommendation: Choose wear-resistant, low-resistance structures
Valve material directly determines service life and maintenance costs:
✅ Cast Iron / Ductile Iron: Suitable for general municipal sewage systems, high cost-effectiveness
✅ Carbon Steel: High strength, suitable for medium and high-pressure conditions, requires anti-corrosion treatment
✅ Stainless Steel (304 / 316): Excellent corrosion resistance, suitable for industrial wastewater and reclaimed water systems
✅ Rubber-lined / Fluorine-lined Valves: Suitable for highly corrosive, particle-containing media
WEIZIDOM can provide professional material selection recommendations based on different wastewater compositions and operating conditions.
Traditional decentralized procurement models have problems such as inconsistent models, unstable delivery times, and insufficient technical support. A one-stop procurement solution offers significant advantages:
🔹 Unified selection, reducing matching risks
🔹 Centralized supply, shortening project cycles
🔹 Overall optimization of technical solutions
🔹 Clear after-sales and warranty responsibilities
For large-scale wastewater treatment projects, one-stop valve procurement is an effective way to reduce overall costs and project risks.
