A PPR Manual Temperature Control Valve is a valve made of PPR material that allows for manual adjustment of the flow rate of the medium in a pipeline, thereby achieving temperature regulation. This product is mainly used in heating, cooling, and other fluid systems for manual control of the temperature of the medium within the pipeline.
Advantages
- Pressure-bearing: The valve body is made of polypropylene (PPR) material, with a rated working pressure ≤1.6MPa.
- Wide-temperature range: The valve is suitable for media temperatures from -10℃ to 95℃, with reliable opening and closing.
- Self-resetting structure: The return spring inside the valve core provides thrust when the temperature bulb contracts, allowing the valve to automatically restore its opening degree.
- Reliable sealing: The valve core seal is made of heat-resistant polymer material, and its elastic recovery capability within the temperature range maintains a leakage rate ≤0.01%.
- Modular design: The valve core and temperature bulb can be independently disassembled; replacement or maintenance does not affect the valve body's pressure-bearing capacity.
FAQ
Q: What are the application scenarios for PPR manual temperature control valves?
A: They are mainly suitable for residential/commercial centralized heating systems (such as radiators and underfloor heating collectors), central air conditioning water circulation systems, and hot water supply pipelines. Their core function is to manually adjust fluid temperature and flow rate, achieving precise local temperature control and adapting to the media transport requirements of PPR piping systems.
Q: What are the working pressure and temperature range of the PPR manual temperature control valve?
A: This product has a rated working pressure ≤1.6MPa (applicable to PN16 pressure rating) and a working temperature range of -10℃ to 95℃. It can meet the requirements of conventional hot water and heating media, but is prohibited from use in steam or excessively hot/pressure environments.
Q: Are there any requirements for the installation direction of the PPR manual temperature control valve?
A: Yes, there are specific installation direction requirements! The arrow marked "FLOW" on the valve body should point in the same direction as the flow of the medium in the pipeline. Do not install it in reverse, otherwise it will cause temperature regulation failure, abnormal flow, or even damage to the valve core.
Q: Is regular maintenance required during daily use? What is the maintenance cycle?
A: It is recommended to perform simple maintenance every 6-12 months: ① Rotate the handwheel to check if the adjustment is smooth and if there is any jamming; ② Wipe the surface of the valve body to remove dust and water stains to prevent the accumulation of impurities; ③ Check for leaks at the interface. If there is a slight leak, tighten the interface or replace the sealing gasket.
