The OV thermostat valve of the AV 9 series is a high-quality radiator valve specifically designed for use in two-pipe central heating systems with forced circulation. It features a continuously adjustable presetting that allows for precise heating output adjustment. The valve is made of nickel-plated brass, which not only provides an attractive appearance but also enhances durability and corrosion resistance. The presetting is simple and convenient with a special presetting key. The valve is thermostatically controlled, enabling efficient regulation of room temperature. It is important to note that this valve is not suitable for heating systems with steam. Additionally, the design allows for the replacement of valve inserts without draining the heating system, significantly easing maintenance.
