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.
Set Up. Pressure reducing valves have several parts. The inlet and outlet ends are connected to the piping where needed. Other parts include a spring, a diaphragm, and a pintle. The spring and diaphragm are on the side of the valve, and the pintle moves in the middle to open and close the valve to relieve the pressure.he inlet and outlet ends are connected to the piping where needed.
