Air Regulators
Marsh Bellofram Compressed Air Regulators are designed to provide cost-effectiveness and user-friendliness through a modular design, which simplifies maintenance and swapping of filter, regulator or lubricator. The units provide output pressure ranges of 0-30, 0-60, and 0-120 psi, NPT pipe sizes of 3/8”, 1/2”, 3/4” and 1”, with a 145 psi maximum supply pressure. Customers can also choose from 5 or 50 micron filters and three types of drains – manual, semi-automatic and automatic.

Current to Pressure Transducers
Marsh Bellofram designs and manufactures high-precision voltage-to-pressure (E/P), current-to-pressure (I/P), and pressure-to-current (P/I) transducers for a variety of industrial and OEM applications. These electro-pneumatic transducers are designed to provide reliability and precise control while operating in harsh environments.

Electronic Pressure Transducer
Marsh Bellofram electro-pneumatic transducers are used to convert current or voltage input signals to proportional output pressures. They are used for process control in valves, pneumatic relays and flow regulators. The PCD division of Marsh Bellofram designs and manufactures high-precision voltage-to-pressure (E/P), current-to-pressure (I/P), and pressure-to-current (P/I) transducers for a variety of industrial and OEM applications.

Pressure Gauges
The Marsh Bellofram name has been synonymous with the design, manufacture and supply of the highest quality pressure gauges and thermometers, with one of the most comprehensive gauge lines in the world. Marsh Bellofram pressure gauges are used in countless applications where accuracy, dependability and durability are essential. Whether a standard or a specially designed pressure gauge, these highly rugged precision instruments are adaptable to wherever pressure or temperature measurements are required.

Air / Process Gas Pressure Regulators
Direct-acting, high-performance Marsh Bellofram air pressure regulators offer precision control, high-accuracy, maximum stability, large flow and exhaust capabilities to support even the most challenging OEM and industrial applications.
