High-Low Pilots Manifold Assembly for Control Systems

High-Low Pilots Manifold Assembly for Control SystemsTwo HL-2 pilots can be mounted on a manifold to produce a high-low (PSHL) assembly for pressures to 10,000 PSI (689.5 BAR). Any two ranges can be used with consideration of the maximum working pressure for the low pilot. The pilots are block-and-bleed valve devices. One is set to monitor low pressure and the other high pressure. A common pressure is sensed through the manifold block. If either the high or low limit is reached, the assembly blocks and bleeds control pressure to provide failsafe shutdown of the system.
