Poppet check valve EC082B

seat

The EC082B is a directional eletric valve pilot acting. An electric impulse open (normally closed configuration) or close (normaly open configuration) the flow through the valve. Once closed, the valve is sealed only in one direction while in the opposite one the free flow is allowed. In EC082B electric valves the force generated by a magnetic field fed by an electric coil is transformed into a mechanical action able to command the opening or closing of the valve, allowing or interrupting the flow passage. The EC082B valves are available in NC configuration (valve closed in absence of power supply) or NO (valve open in absence of power supply). Typical application of these valves is the unloading function: a normally open valve discharges the pumpf flow, preventing movement of the actuators until an electrical impulse closes the passage to tank, making the flow available for use. For the NC version an emergency command is also available for manual opening of the valve in the event of an interruption of the electrical signal. The presence of a poppet and a sealing seat allows the EC082B valves to be used as check valves able to support a load thanks to the absence of leakage when closed. A typical example of application in this sense is the block in position and the consent to the descent of a single-acting cylinder. The EC082B valves are single-sealed; the block valve function is only possible in one direction while in the opposite direction the flow passage is free.
