Masoneilan 535H-536H Series Pressure Regulators


The Masoneilan Model 535H / 536H pressure regulators from GE are designed to provide accurate reduced pressures of air, liquid, saturated and superheated steam. They are available in sizes ¾", 1", 1 ½" and 2" with full area and reduced trim to handle the small-to-moderate flow applications where IEC 60534-4/ANSI/FCI 70.2 Class IV or VI shut-off is required. For temperatures over the rating of the diaphragm material, the regulator must be mounted with the actuator below the centerline of the regulator body. The diaphragm will be protected from the high temperature by a condensate barrier in the sensing line and actuator diaphragm case. If installed otherwise, an adequate condensate barrier must be incorporated. Consult factory for more information. Refer to Specification Data CY5010 for actuator selection.
