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.
How Hydraulic Rotary Vane Actuators Work. Hydraulic rotary vane actuators use a system of vanes to produce force by means of hydraulics. Pneumatic applications are useful in situations where large amounts of force at not required. For more muscle, hydraulics are the type of cylinder actuators you want.In both types a closed chamber resides on both ends of a shaft. Applying pressure to one side moves the shaft in the desired rotary direction.neumatic applications are useful in situations where large amounts of force at not required.
