Air Pressure Regulators

Air Regulators Literature

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.

Pneumatic (Air) Relays

Relays & Volume Boosters

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.

Electro-Pneumatic

PCD Transducers Literature

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.

Servo Pressure Controllers

Type 3000 Literature

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

Air Cylinders Literature

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

Bellofram FRLs Literature

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.
