Abstract
Tilting of a main valve assembly under high inlet pressure conditions is prevented by supporting the main valve assembly with housing rib engaging a skirt on the main valve guide tube. Pilot valve opening results from contact of an enlargement on the pilot valve stem with the push rod as the pilot valve begins its upward movement. An off center baffle compensates for the pressure pattern resulting from the side entry inlet. Throttling structure provided by a skirt on the guide tube cooperating with a shoulder in the outlet passage provides a desirable large flush flow. The inlet and handle openings in the valve body include bosses adjacent thereto an internal to the housing.
