Based on the aforementioned working conditions, the GRAT electric water supply regulating valves have become the preferred choice for numerous industrial refrigeration users due to their high-precision regulation and excellent sealing performance. After applying the GRAT electric water supply valve to a central air-conditioning chilled water unit, the customer provided the following operational data:
Enables micro-regulation as low as 1L/min, supported by a CF8 stainless steel valve body and PTFE+HNBR composite sealing. Zero medium leakage throughout service ensures safety and environmental compliance.
Temperature control deviation reduced by 65%, while the average annual failure rate decreased from 3.2 to below 0.5. Original factory precision is maintained even after 5 years of continuous operation.
Achieved an annual reduction in maintenance expenses of approximately ¥45,000, alongside an 82% decrease in unplanned downtime due to valve-related issues, significantly improving cost-effectiveness and production availability.
Cooling efficiency increased by 6.8%, contributing to lower energy consumption and enhanced operational sustainability.
The GRAT electric water supply regulating valve automatically adjusts flow rates and primarily consists of an electric actuator and a valve body. It offers broad applicability, high precision, and rapid response, making it ideal for scenarios requiring fast adjustments.
In HVAC applications, the valve is widely used in heating and cooling systems. It modulates cold or hot water flow by automatically adjusting the opening based on real-time room temperature feedback, ensuring a consistent and comfortable indoor climate.
In boiler systems, the valve serves as a critical component in automatic feedwater regulation. Its precisely designed throttle element adapts to varying pressure differentials, maintaining stable drum water levels while preventing media backflow and leakage, thereby enhancing system safety and cleanliness.
In summary, the GRAT electric water supply regulating valve has extensive applications in HVAC, refrigeration, boilers/industrial furnaces, primarily used for flow control, temperature regulation, and medium flow control, thus enhancing system stability and efficiency. We remain committed to continuous technological innovation and lean manufacturing to provide smarter and more reliable fluid control solutions for industrial customers worldwide, aiding in the long-term goal of achieving efficient energy savings and stable operation of systems.
