Motorized valves by Kromschröder are used for safeguarding, regulating and controlling the gas and air supply on gas burners and gas appliances. The valves, composed of the actuator and the lower housing, offer safe shut-off and control of the fuel and gas burners, and gas appliances in heating systems and thermal-process installations. Their features include robust design and long service life, plus current saving features such as automatic motor switch-off. The explosion-proof actuators offer enhanced safety, due to oil encapsulation. They are also EC-type tested and certified and are available in various housing types and nominal sizes.
