The digital locking balance valve is an adjustable valve with a special function of digital locking. it adopts a dc type valve body structure and has better percentage flow characteristics. it can reasonably distribute flow rates and effectively solve the problem of uneven room temperature in the heat supply (air conditioning) system.
Overview At the same time, it can accurately adjust the pressure drop and flow rate, which can be used to improve the liquid flow state in the pipe mesh system to achieve the purpose of liquid balance and saving energy. The digital locking balance valve is equipped with an opening degree indication, opening locking device and a small pressure measuring valve for flow measurement. As long as the balance valve of appropriate grids is installed on each branch and user entrance, it can be locked after one-time debugging with a dedicated smart instrument, and the total water volume of the system can be controlled within a reasonable range, overcoming the unreasonable phenomenon of "large flow and small temperature differences". Sp45f balance valve is an ideal product in the heating system. It can be installed on the water supply pipe, or it can be installed on the return pipe. generally, we recommend that it be installed on the return pipe, especially for high temperature loop, in order to facilitate debugging, it should be installed on the return pipe, and the supply (return) water pipe with a balanced valve is installed. there is no need to set a shut-off valve.
Product Features This valve is a balance valve that is suitable for a variety of liquid pipeline systems. it is an ideal new type of energy-saving valve. the valve is equipped with a scale digital display, which can be easily adjusted to the next slot position and can be locked. The valve is mainly used in industrial and civil building heating pipeline systems. There are problems with water intake in some pipeline systems, balance valves provide a means to solve this problem, use it to accurately regulate pressure reduction and flow rate to improve the liquid flow conditions in the pipeline system, to achieve the purpose of plumbing liquid balance and saving energy. In the double-tube network engineering modification, this valve can save energy and get better results.

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.
