This control valve is designed to self-regulate based on the pressure differences, allowing for a precise and constant control of the network media and temperatures for the entire system. It is a two-way, high-performance valve with a built-in non-return valve and an integrated, non-contact temperature sensor. The valve is made of stainless steel, making it corrosion-resistant and highly durable.
