Product Groups
Precision Air 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.
Electronic Pressure Transducers
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.
Pneumatic (Air) Relays
Marsh Bellofram pneumatic relays are designed to provide cost-effective, high-performance air regulation across a variety of applications, and in support of a variety of market requirements. Available versions and types include two-stage, pilot operating 1:1; positive and negative biasing, positive bias booster, high relief, adjustable bias, and ratio high-flow relays, all of which provide highly accurate and reliable output pressure control.
Servo Pressure Controllers
Marsh Bellofram designs and manufactures a complete line of servo pressure controllers, including both traditional and analog circuit card models, to suit a variety of OEM, industrial, HVAC and medical device and equipment process control applications.
Diaphragm Air Cylinders
Marsh Bellofram diaphragm Air Cylinders are actuators made from elastomers, engineered metals and fabrics. They require no lubrication and are virtually frictionless and economical. They can be used to provide lifting, clamping, pushing, coining, turning and other linear force or actuation motions in many applications.
Filter Regulator Lubricator
Marsh Bellofram Filter-Regulator-Lubricators (FRLs) are designed with economy and convenience in mind. Filter Regulators have the same features as the regulators with the addition of polycarbonate bowls, 5 or 50 micron filters, and with manual, semi-automatic or automatic drains. Lubricators feature polycarbonate bowls, with field- settable dials providing variable lubrication between 0 and 90 drips per minute.
Accessories & Add Ons
Digital Pressure Indicator
The Marsh Instruments Digital Pressure Indicator is portable, lightweight, hand-held testing and calibrating instrument indicates pressure to 50 psig at accuracy levels of ±0.25% of reading ±1 count. A state-of-the-art semiconductor-type pressure transducer converts pressure input to analog voltage, which is displayed on 3-1⁄2 digit LCD readout. Internal 9-volt rechargeable battery powers the indicator, and a zero adjust potentiometer standardizes the transducer bridge at zero pressure for higher accuracy.
