Основные преимущества и выгоды
-
High-Capacity Liquid Control: Specifically optimized for high-volume liquid service, the MR105 manages large flow rates with a low pressure drop, ensuring system efficiency in cooling and lubrication circuits.
-
Fast Speed of Response: Because the sensing diaphragm is directly linked to the valve plug, the MR105 reacts immediately to changes in downstream demand, preventing pressure spikes in sensitive equipment.
-
Dirty Service Reliability: The robust internal design is less susceptible to clogging or sticking than pilot-operated alternatives, allowing it to perform reliably in “dirty” service where particulates may be present in the fluid.
-
API 614 Compliance: Available in Steel and Stainless Steel constructions that meet the stringent requirements of API 614 for lubrication, shaft-sealing, and control-oil systems.
-
NACE Sour Gas Readiness: Optional constructions are available to meet NACE MR0175 and MR0103 standards, providing essential safety and durability in sour gas environments or corrosive chemical processes.
-
Operational Versatility:
-
Pressure-Loaded Actuator: Allows for remote setpoint adjustment or differential pressure control by loading the actuator with an external gas source.
-
P1 = P2 Capability: On high-pressure actuator versions, the design allows the inlet pressure to equal the outlet pressure rating, providing a higher safety margin for the casing.
-
-
Integrated Maintenance Tools: Features like the standard drain valve and optional bleed valve (for high-pressure units) simplify the depressurization and cleaning process during routine maintenance.
-
Visual Travel Indicator: A standard travel indicator allows operators to monitor the valve plug position in real-time, facilitating easier troubleshooting and performance verification.
