Top and Bottom Guiding
A well accepted industry standard particularly suited for double seated plugs to provide adequate support against side loads.
Masoneilan 525-526 Series
Pressure Reducing, Back Pressure & Differential Pressure Regulators
High Capacity with Low Recovery
Flow capacity is at top levels for contemporary double seated regulators and is attained with very little pressure recovery as indicated by a high critical flow factor.
Reduced Capacity Trim
0.4 Factor Trim - the most practical double seated trim design giving a substantial reduction in capacity while maintaining desirable flow characteristics.
High Performance Materials
Materials of construction have been selected for high performance and long life when handling the high pressure drop capabilities of the valve.
High Temperature Applications
For high temperatures, mount the regulator with the actuator below the body to protect the diaphragm. This allows a condensate barrier to form. If not, a separate barrier is required—consult the factory.
Configurations
Models 525 and 526 Regulators are designed for use with the 10900 Series Actuators for reducing, back pressure and differential pressure applications.
