| description | A poppet-type check valve utilizing an integral detachable flow control assembly for insertion into a cooperating housing. The checking poppet is oriented with its actuating stem, concentric guide, and concentric force bias spring downstream of the check flow controlled orifice. In a preferred embodiment, the flow control assembly is located internal of a housing having a first flow length adjacent the controlled flow orifice and seat, and a second converging flow length abutting said first flow length, and a terminating flow outlet adjacent the valve outlet port. When mounted internal of the preferred housing, the valve poppet assembly lies partially within the first flow area and extends a predetermined distance into the converging section, thereby greatly reducing turbulence and having a demonstrated reduction in medium flow pressure drop over presently used units. |
