Brass T/P Valve

1,Size:1/2--3/4. 2.Manufacturer 3.Brand:AKE WYA-15,WYA-20 4.ISO9001,CE cetificate.

Function:The T/P relief valve controls and limits the te:mperature and pressureof the hot water contained in a solar domestic water storage heaterand prevents it from being able to reach temperatures of over100°C, with the formation of steam.On reaching the settings, the valve discharges a sufficient amountof water into the atmosphere so that the temperature and pressurereturn within the system’s operating limits.

Operating principle:The valve opens the outlet on reaching the settings for:- temperature: the thermostat compound inside the temperature sensor 1), submerged in the hot water storage heater, expands as the temperature increases. This expansion causes a thrustpin to move and act on the obturator 2) opening the valve. The valve is set to open at temperatures of over 99°C.- pressure: the obturator, opposed by a set spring, raises on reaching the pressure setting and opens the outlet completely. The pressure setting is chosen according to the maximum permissible pressure in the system.As the temperature and pressure decrease, the opposite action occurs with the valve subsequently reclosing within the set tolerances.

Installation:Before installing a TP relief valve it is necessary for the sizing to be performed correctly by specialized technical personnel in accordance with the current regulations for the specific applications. Any use other than the intended use is prohibited.The TP relief valves must be installed by qualified technical personnel in accordance with current regulations.The TP relief valves must be installed observing the direction of flow indicated by the arrow on the valve body.
