The pressure reducing valve will flow up and down with different water pressure. it can supply water downstream according to the user's set pressure, and the water supply pressure is not affected by the import pressure fluctuations and exit flow changes. the pressure reducing guide valve can set downstream pressure value. Its installation improves the difference in pressure in various areas of the same system, and can completely replace the traditional partition water supply form, greatly reducing engineering costs, increasing architectural utilization area, and improving water efficiency.
Overview The product is designed for high-level ultra-high-rise buildings. it is an ideal product to solve the problem of water for living in high-rise buildings and fire water systems, requiring large flow rate and high sensitivity in various occasions. Its performance is more superior, completely replacing the intermediate water tank, saving the cost of the water tank in the building and expanding the usage area of the building.
Product Features 1. This valve is easy to adjust and operate, with a large adjustment range
2. Excellent performance, the set pressure does not change due to changes in upstream pressure and downstream flow.
3. The action of the valve is adjustable, sensitive and stable.
4. The film is isolated, reliable and has no wearing parts, and has a long service life.
5. Small size and can be installed at any angle.
Technical Specifications Installation Requirements
It is recommended to install the exhaust valve in the pipe net system,while the pressure reducing valve can work stably.When installing,pay attention to the direction of the valve body and arrow marking. To facilitate maintenance,you should leave a certain amount of space around the pressure reducing valve.The inlet and outlet pressure should not be less than 0.2mpa,less than 0.2mpa voltage stabilization performance has deteriorated (export pressure error is enlarged).

FAQ As a global supply chain service provider with operations in over 30 countries and regions, our comprehensive product range—encompassing pipes, fittings, valves, and fire-fighting equipment—has obtained ISO international quality certification and complies with multiple regional standards, including CE, UL, and SASO. These products have been successfully implemented in various international scenarios, such as infrastructure projects in Southeast Asia, commercial complexes in the Middle East, and fire renovation projects in Eastern Europe. For both regular procurement and cross-border customization, we offer an integrated solution that spans product selection, customs clearance, and logistics management.
Absolutely. For overseas customization requests, our engineering team collaborates directly with international blueprints and technical specifications to provide multi-standard compatible designs, including wall thickness conversion and pressure grade adaptation. Additionally, we provide:
- Third-party testing reports for pre-production samples
- Packaging labels compliant with the destination country's regulations
- Bilingual technical documentation and compliance certificates to ensure smooth local acceptance
We enforce a global quality control system that surpasses national standards. Each batch undergoes rigorous testing, including raw material composition analysis, pressure burst tests, and salt spray corrosion resistance evaluations, accompanied by bilingual (Chinese-English) quality inspection reports. Based on project location requirements, we can furnish free certification documents for target markets, such as CE (European Union), UL (United States), and BIS (India). Furthermore, we support on-site inspections and remote video audits to ensure full transparency in the quality control process.
The standard delivery cycle for overseas orders ranges from 25 to 45 working days. We offer diverse shipping options, including full container loads, less-than-container loads, and air freight express services. Our international logistics network covers major ports and airports worldwide. To facilitate swift customs clearance, we provide essential international certification documents, such as certificates of origin and commercial invoices. Leveraging our bonded warehouses in Hong Kong and Shenzhen, select Southeast Asian orders can be expedited with delivery within 7 to 10 days.
We deliver cross-border after-sales support through a 7x12-hour customer service model (email/WhatsApp/phone) with a guaranteed response time of two hours and a resolution proposal within 24 hours. For warranty-related quality issues, we cover basic shipping costs from Chinese ports or airports to the destination port. Additionally, we provide remote technical guidance, bilingual materials, and coordinate online support with engineers when necessary.
Absolutely. As a one-stop supplier, we specialize in customizing products to match your unique project needs:
Customizable parameters: Pipe diameter (DN15-DN2000), valve pressure rating (PN10-PN400), material (304/316 stainless steel, carbon steel, galvanized steel);
Fire system customization: We collaborate with your engineers to design integrated systems (e.g., high-rise building fire pipelines + matching valves + sprinklers) and provide 2D/3D drawings for confirmation before production.
Sample production is available for testing prior to mass orders.
