Kidney failure can occur as a result of hypercalcemia and then compound the problem as a further cause of imbalance. Disturbances in nerve conductivity and cardiac muscle contractions can ultimately cause neurologic tremors or seizures, weakness, and cardiac arrhythmias. If the levels remain significantly elevated, calcium can be deposited in any soft tissue or organ system in the body. Left untreated, hypercalcemia can be fatal.
Use proportional control valves to reduce shock and give a finer degree of control to circuits that do not require extreme position accuracy, or repeatable speed and force. Proportional valves restrict flow to and from an actuator. They work best with a pressure-compensated pump in a closed-center circuit.
A: A proportioning valve is a pressure reduction device. It is typically installed in the rear brake line to reduce braking efficiency and compensate for premature rear-wheel lockup; a result of incorrect front to rear brake bias. An adjustable proportioning valve permits incremental adjustments to fine tune brake bias.his ability to adjust front-rear brake bias is particularly important in race applications, as changing track conditions and vehicle dynamics usually require the brake bias be adjusted throughout the race. Normally, you do not need to purchase a proportioning valve with a Wilwood four-wheel disc brake kit.
