Standard NBR seals can withstand water temperatures up to +85°C. This makes them suitable for a wide range of typical hot water applications.
EPDM seals offer a significant advantage in hot water applications as they increase the maximum temperature capability. For valve sizes 3/8" to 3/4", EPDM seals allow for temperatures up to 150°C, and for valve sizes 1" to 1½", temperatures up to 130°C are feasible. This extended temperature range makes EPDM seals ideal for more demanding hot water systems.
If the hot water temperature exceeds the capabilities of EPDM seals, it's recommended to use ASCO Steam valve ranges instead. These valves are specifically designed to handle higher temperatures typically encountered in steam applications.
ASCO offers several valve series suitable for hot water service, including the 238, 222, 210, and 220 Series. Each series may have different features and capabilities, so it's essential to select the appropriate model based on the specific application requirements.
Many ranges of ASCO valves can cope with hot water duty, but the specific valve model to be chosen varies depending on the maximum temperature requirement. It's crucial to select the appropriate valve with seals that can handle the expected temperature range of the hot water.
The maximum temperature range depends on the seal material used. With EPDM seals, temperatures can go up to 150°C for valve sizes 3/8" to 3/4", and up to 130°C for valve sizes 1" to 1½".
When selecting a valve, it's crucial to consider not only the maximum temperature of the hot water but also factors such as pressure, flow rate, and compatibility with the fluid and system components. This ensures the chosen valve can operate reliably under the expected conditions without degradation.
No, for temperatures above 150°C, ASCO Steam valve ranges are recommended instead of hot water valves. Steam valves are designed specifically to handle the higher temperatures typically found in steam applications.
Yes, the limitations depend on the seal material and valve series chosen. It's essential to choose the appropriate valve based on the maximum temperature requirement of the hot water system to ensure optimal performance and longevity.
ASCO hot water valves are specifically designed for hot water applications and have seals suitable for lower temperature ranges compared to steam valves. Steam valves, on the other hand, are engineered to withstand higher temperatures typically found in steam systems.
ASCO solenoid valves are designed to handle high-pressure applications, including hot water systems. However, it's essential to ensure that the selected valve is suitable for both the temperature and pressure of the specific hot water system to ensure safe and reliable operation.

Yes, ASCO solenoid valves are designed for continuous operation in hot water systems. However, proper sizing and selection are crucial to ensure that the valve can withstand the operating conditions and provide reliable performance over time. Regular maintenance and monitoring are also recommended to ensure optimal valve performance and longevity.
