The Mark 80 Series Temperature Regulator features the advanced sliding gate seat technology pioneered by Jordan Valve. Using the Jordan Valve sliding gate seat technology, the Mark 80 temperature regulators have the signature straight-through flow, short-stroke that is 1/3 of a globe-style valve, quiet operation and tight shutoff. The Jordan Valve Mark 80 has high rangebility and extremely accurate regulation.
The Mark 82 is an internally piloted regulator offering better accuracy than a direct acting temperature regulator. The MK82 is available in two configurations, reverse and direct. The internal pilot valve seats and the main valve seats, in resting position, are up and closed. As the process temperature rises, the fluid in the sensing bulb vaporizes to apply pressure to the pilot diaphragm, opening the pilot valve. The upstream pressure passes through the pilot valve and the pilot port, opening the main valve to provide the required cooling action.
The Mark 85 Series is a self-operated temperature regulator with a controlled failure option, which allows you to predetermine the position of the valve in the event of thermal system failure. The Mark 85 is designed to fail closed on heating applications and to fail open on cooling applications.
The MK85 is ideal for applications with slow temperature changes such as autoclaves and large storage tanks.
The Mark 86 Ambient Temperature Regulator is designed to control steam-tracing lines based on ambient temperatures. Steam tracing lines are commonly used to protect outdoor instrumentation, pipelines, and tanks from freezing. The Mark 86 allows steam to flow through the tracer lines only when it is needed and remains closed when the ambient temperature rises above a predetermined set point.
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. Utilizing the same technology as the industry-leading, self-contained Mark 80 Temperature Regulator, the Mark 87 is a piloted temperature regulator that offers quality and performance unparalleled by any competitive product on the market.
