An electromagnetically actuable proportional hydraulic valve ( ) is described, which is distinguished in particular by a constant, low-wear operating performance. This is attained by means of a closing member ( ) having an approximately conical sealing body ( ) with a curved dome-like face end oriented toward the valve seat ( ). The sealing body ( ) together with the valve seat ( ) forms a conical seat valve. The sealing body of the closing member ( ) is provided with a flow separation edge ( ), which improves the temperature sensitivity of the proportional valve ( ).
