Relief valve for WYA-20 99C 102PSI 210F 0.7Mpa temperature controlIntroduction: Temperature and Pressure Safety Valves ( / P Valves)<br> 0.7Mpa applies = 102PSI<br> Detailed introduction:<br> Temperature and pressure relief valves ( valves) are suitable for other sensitive heaters such as solar , electric heaters, heat pump , various heating functions (such as boilers).<br> The valve can automatically reduce the temperature and pressure, and has the dual safety protection function of temperature and pressure. It is the safety protector of the current pressure water heater.<br> Features:<br> Safety relief valves are commonly used to control the pressure in boilers in heating systems, hot water tanks stored in domestic hot water systems, and general water systems.<br> When the calibrated pressure is reached, the valve opens and, by venting to the atmosphere, prevents the system from reaching pressure levels that are dangerous to the components in the boiler and the system itself.<br> Calibration pressure: 0.1, 0.15, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0 Mpa;<br> Deviation: When not more than 0.5Mpa, the deviation is 0.015Mpa, and when it is 0.5Mpa, the deviation is 3% of the rated pressure.<br> Technical specifications:<br> color:gold<br> material:<br> Body: 3/4 inch ; brass<br> Control spindle: brass<br> Closed hole: silicone gel gasket<br> Spring: SUS304 stainless steel<br> Nominal pressure: PN10<br> Temperature range: 5-110 ° C<br> Set pressure: 0.5, 0.6, 0.7, 0.8, 0.9, 1.0 MPa<br> Set pressure deviation: -10%-5% set pressure<br> Set temperature: 99±4 degrees Celsius<br> Entrance and exit (middle): BSPP 3/4 * 3/4<br> Weight (g): 238g<br> size:83 * 42mm<br> Package included:<br> 1 * Pressure Valve<br> Only the above package content, other products are not included.<br> Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
