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.
The Type 37 regulator is specifically designed for applications that require large flow capability and accurate pressure control. This regulator offers low droop, high accuracy, and fine adjustment sensitivity.
The Bellofram T39 regulator selection is the largest of its type in the industry. We offer this regulator in three different materials, one of which will ideally suit your application AND your budget. ALL of the T39 regulators are offered […]
The Marsh Bellofram Type 50 & Type 50 NACE 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).
Bellofram’s T65 Air Regulators are reliable precision units designed for instrumentation and general purpose use. The Type 65 is a preset, fixed-pressure unit without a dripwell (Dripwell unit available as T60).
The Type 70BP back pressure air regulator is a high-flow, high-precision pneumatic relief valve with adjustable set point. It is expressly designed for applications requiring high flow capacity and accurate pressure controls.
The Bellofram T77 Vacuum Regulator incorporates a fixed negative 15 psig bias spring to maintain vacuum outputs up to 29″ Hg. An adjustable opposing range spring increases controlled pressure outputs up to 150 psig.
The T95H is a direct operating pressure reducing regulator with large capacity. Ideally suited for uses in oil and gas, process gases, steam and liquids. Available in three spring ranges and metal or elastomer diaphragm and orifice seat materials.
The T98H monitors upstream pressure and opens to relieve excess pressure increases above setpoint. As an industrial steam, water and process liquid Back Pressure Regulator, the upstream pressure is monitored and released downstream when the setpoint is exceeded.
The T1808 pilot-operated relief valve or back pressure regulator is used in gas or liquid service to maintain pressure on oil and gas separators, and in pressure relief applications in industrial gas distribution systems. The function of the T1808 is […]
