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.

The Electro-Pneumatic Positioner GT-100L is used for operation of pneumatic linearvalve actuators by means of electrical controller or control system with an analog output signal ofDC 4 to 20mA or splitranges.

The Marsh Bellofram Type 50/Type 50 NACE Precision Filter Air Set Regulators are reliable, precision filter air set pressure regulators, designed for instrumentation and general purpose use in both standard (Type 50) and corrosive environments (Type 50 NACE). The Type 50 NACE complies with NACE material requirement #MR-01-75 for sulfide stress cracking-resistant metallic materials for oil field equipment.

The rugged design and construction of the Type 50 includes the incorporation of die cast aluminum housings that are finished with epoxy paint for added protection against scratching, weathering and other challenging environments. Careful design and use of quality materials ensure long, trouble-free operation, even in the most difficult of industrial environments. The user-adjustable Type 50 series offers superior pressure regulation vs. flow characteristics, excellent stability, repeatability and built-in filter with dripwell. A rubberized, soft-seat valve stem provides positive shut-off and forgives dirt or other foreign matter. An aspirator maintains

downstream pressure and compensates for droop when high flow occurs. A gauge port facilitates convenient gauge installation and can be used as an additional full flow outlet. In addition, Type 50 NACE regulators include an easily serviceable and self-cleaning 316 stainless steel mesh filter that can be side, panel, pipe or through-body mounted.

Marsh Bellofram Small Bore 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.

The development of the long stroke rolling diaphragm for dynamic sealing has been field-proven as a reliable solution for many applications requiring low friction, no lubrication, low leakage, wide temperature variations and low total cost of ownership. The popularity of the rolling diaphragm as a sealing means led to many requests for a standard line of off the shelf diaphragm cylinders; single and double acting, short and long stroke with a wide selection of effective areas. To meet these requests, the long stroke rolling diaphragm cylinder was developed; Marsh

Bellofram has supplied many thousands of them since their 1965 introduction. Belloframs 0.38 and 1.7 sq. inch effective area diaphragm cylinders combine the performance of the diaphragm cylinder with small size. Two different stroke options are available in each size, with either flush or extended rods on 0.38 sq. inch cylinders. Only spring return varieties are available.

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.
