MIL 41000 SINGLE SEATED HEAVY DUTY CAGE GUIDED GLOBE CONTROL VALVES
Overview
§ High allowable pressure drops: Cage Guided valves provide exceptional performance over a wide range of pressure drops in severe services. They also handle most shut-off pressures with standard pneumatic spring diaphragm Actuators.
§ High capacity with low pressure recovery: Flow capacities remain at top levels, and are attained with minimum pressure recovery reducing the possibility of Cavitation in liquid service.
§ Standardised high performance material: This ensures trouble free operation even in applications with inherent high pressure drops and extreme temperatures.
§ Tight shut off valves: For lower sizes, unbalanced design results in Class V leakage. For higher sizes, the exceptional single seated leak tightness of Class V is achieved by the following special options:
· Auxiliary shut-off pilot plug closes the balancing holes located in the main plug in shut-off conditions.
· Self energised seal rings pressing against walls of the Cage & Plug arrests leakage past the seal ring.
§ Lo-dB/Anti-Cavitation Cages: Noise attenuation and Cavitation control achieved by replacing conventional Cages with Lo-dB Cages
