Diaphragm relief valve WW-730

hydraulically-operated

The Model 730 Pressure Relief/Sustaining Valve is a hydraulically operated, diaphragm actuated control valve that can fulfill either of two separate functions. When installed in-line, it sustains minimum pre-set, upstream (back) pressure regardless of fluctuating flow or varying downstream pressure. When installed as a circulation valve, it relieves excessive line pressure when above maximum pre-set. Product features & benefits •Line pressure driven – Independent operation •Balanced seal disk – High relief flow capacity •In-line serviceable – Easy maintenance •Double chamber design oModerated valve reaction oProtected diaphragm •Flexible design – Easy addition of features •Variety of accessories – Perfect mission matching •“Y” or angle, wide body – Minimized pressure loss •Semi-straight flow – Non-turbulent flow •Stainless Steel raised seat – Cavitation damage resistant •Obstacle free, full bore – Uncompromising reliability •V-Port Throttling Plug – Low flow stability”
