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.
Getting the terminology right. Not every block on your car is a Proportioning Valve!!! Proportioning Valve-A proportioning valve restricts the amount of pressure to the rear of a brake system under heavier braking conditions to prevent the rear brakes from locking up too soon.Proportioning valves were usually only found on vehicles with front disc brakes.967-1970 GM A / F / X body proportioning valves. These valves mount on the frame inline in the brake line that runs from the distribution block to the hose at the center of the rear axle. Not all cars with disc brakes had this style of valve.
