Kromschroder Gas solenoid valve VAS240R/LW 88006283

The Kromschroder VAS240R/LW is a gas solenoid valve with a nominal diameter of 40 mm and a connection thread of Rp 1 1/2. It operates at a supply voltage of 230 V and a frequency of 50 Hz, with a maximum inlet pressure of 500 mbar. The valve features slow opening and quick closing, with a closing time of 1 second, and includes flow adjustment. It has a double valve seat, a strainer made of AISI 303 stainless steel, and a blue LED indicator. The valve is normally closed and certified to 2009/142/eu, EN 13611, and EN 161, with safety integrity level SIL 3 and performance level PL e.

Parts of this type are selected by matching the nominal diameter, connection thread, and supply voltage to the existing system. The valve size and flanged connections must correspond to the pipeline diameter range, which for this kind is DN 10 to DN 65, with flanged connections for DN 40 and DN 50. Ensure the electrical connection type (plug without socket) and auxiliary devices (screw plugs) are compatible. The valve's operating principle is electromagnetic, and it is normally closed.

Common failures include the valve not opening or closing properly, often due to coil failure or debris blocking the valve seats. The blue LED may not light up when power is applied, indicating an electrical issue. If the valve fails to close within the specified time, the closing spring may be worn or broken. Check the strainer for clogging, which can cause pressure loss and affect operation.
