Abstract
A pressure reducer has a housing with an inlet and an outlet. A valve disc is located in the housing and a valve stem reciprocally and sealably moves in the valve disc with the outer end secured to a resilient diaphragm. The inner end of the valve stem extends into the inlet and is secured to a tubular closure member which is sealingly positioned in the inlet and is engageable with the valve disc. The surface of the tubular member subjected to pressure in the housing is adpated to equal the combined subjected to opposed pressure surfaces of the tubular member in the inlet and the end of the valve stem to which it is secured. Screens are provided around the tubular member.
