Externally Piloted

The Mark 87 piloted temperature regulator is the sliding gate valve engineered to provide wide rangeability, and greater accuracy, for a variety of temperature control applications. Designed with the same technology as the Mark 80, the Mark 87 is a piloted temperature regulator that offers quality and performance. It can be used where larger line sizes and higher flow rates are required.
