Product description

Air loaded sanitary back pressure reducing valve designed to allow the user to change setpoints remotely via a cabinet or panel  mounted air regulator or though a distributed control system or PLC using a I-P transducer.  Unique among its peers, the Mark 95A is normally open with the air supply is removed, allowing process or sanitization fluids to drain.
