The Model 25 Reversing Relay provides an output which will decrease in direct proportion to an increase in input pressure.
Features
• High strength, deep convolution compensating diaphragm .
• Bottom pressure balancing chamber with a diaphragm .
• Floating seal ring .
• Balances undesirable relief seat forces.
• Ensures balanced supply seat forces.
• Protects stabilizing chamber from effect of high relief flows.
