SINGLE SEATED - closing with inlet pressure for positive dead- end shut-off. 3
ACCURACY OF REGULATION - comparable to instrument control with full flow for equivalent pipe size.
WIDE ADJUSTABLE RANGE - from minimum to maximum of reduced pressure range with easy adjusting screw. No springs or diaphragms to change.
FULLY GUIDED MAIN VALVE - prevents rubbing or binding of internal parts.
PISTON WITH TEFLON SEAL - for temperatures up to 450°F, (232°G) gives continuous wiping action, keeping liner clean, improving reliability and reducing maintenance.
SENSITIVE STAINLESS STEEL DIAPHRAGM re sponds instantly to any flow change and eliminates stuffing boxes and bellows seals. Full travel less than its own thickness minimizes stress.
RENEWABLE, INTERCHANGEABLE PARTS - ma chined to close tolerances; complete overhaul without machining or removing valve body from the line.
REMOTE ADJUSTMENT SUPERSTRUCTURE for convenient adjustment by air loading. See page 10 for details.
GRADUAL OPENING PORTED MAIN VALVE - in sizes 2 1/2” and larger for improved throttling control under low flow conditions.
