[origin: WO2010091851A2] The present invention relates to a poppet valve (105) and a method of regulating fluid flow. A valve body (110) defines a bore (115) and is provided with a valve seat (120). A valve member (125) is provided with a valve stem (130) and a plug (140). A fluid pathway (200) defined between the valve body (110) and the valve member (125). The valve stem (130) can include a first valve stem portion (131) provided with a first diameter (133) and a second valve stem portion (132) provided with a second diameter (134). The fluid pathway (200) comprises a reduced flow orifice (180) defined between the first valve stem portion (131) and the valve body (110) and an enlarged flow orifice (181) defined between the second valve stem portion (132) and the valve body (110).
