Model 760-03-V - Hydraulic Non-Slam Check Valve

The Model 760-03-V Hydraulic Non-Slam Check Valve is a double chambered, hydraulically operated, diaphragm actuated control valve which is hydraulically powered to fully open during system flow when upstream pressure exceeds downstream pressure. If pressure conditions reverse, the valve gradually shuts off drip tight preventing back flow.

Features and Benefits

• Line-pressure driven – Independent operation
• Double chamber
  • Powered opening and closing
  • Moderated valve reaction
  • Protected diaphragm
• Opening and closing speed control – Eliminates system surges
• Balanced seal disk – High flow capacity
• In-line serviceable – Easy maintenance
• Flexible design – Easy addition of features
• "Y" or angle, wide body – Minimal pressure loss
• Semi-straight flow – Non-turbulent flow
• Obstacle free, full bore – Uncompromising reliability
• V-Port Throttling Plug – Smooth closing characteristics

Typical Applications

Pump Check Valve
In this system, a pump battery supplies the main line through a manifold. The Model 760-03-V installed downstream from each pump:

• Prevents reverse flow from damaging pump
• Provides smooth starting and stopping of supplementary pumps
• Allows surge-free switching between “on-duty” pumps
• Delays reaction of variable speed primary pump to single speed supplementary pump going on line or off line.
