摘要： The present invention provides a poppet type directional control valve, in which valve body and valve disc can be manufactured and assembled in easier manner and at low cost. In a directional control valve, in which a poppet type valve disc can be switched over and driven by pilot fluid pressure, and there are provided on a valve body 2 a first valve bore 6a formed from one end toward a first valve seat 7, a second valve bore 6b formed from the other end toward a second valve seat 8, and a communicating valve bore 6c formed from the valve bore 6a and communicating between the first valve seat and the second valve seat. The valve disc comprises a first valve disc 10 inserted through the first valve bore and used for opening and closing the first valve seat and a second valve disc 11 inserted through the second valve bore, connected with the first valve disc and used for opening and closing the second valve seat, and these components are made of a material having elasticity and sealing property. The pilot chamber 18 is formed between the first valve disc airtightly inserted in the second valve bore 6b and a manual operating member 14 for closing an opening of the second valve bore.
