Abstract
A series of valves are disclosed which are specially designed for use in desiccant dryers. Each of the valves utilizes a housing (12), fabricated of standard pipe components and communicating flanges (13, 14) in conjunction with a poppet (24) and seat (20) arrangement. A support (30) fixed to one side of the interior of the housing carries an axial rod (23) to which the poppets (24) are mounted. Two- and three-way valves include a piston (36) and cylinder arrangement within the support to actuate the poppets. The poppet (224) of the check valve (200) is actuated automatically in response to pressure differentials across the poppet.
