Membrane check valve WW-80N

high-pressurestainless steelhydraulic

Overview
The Model 80N is a non-slam lift-type check valve designed to permit flow in one direction and close drip-tight to prevent backflow. Built for pumping, booster and waterworks applications, it offers full-bore flow and a stainless-steel raised seat to resist cavitation.

Features & Benefits

• Non-slam closing – reduces system surge and water hammer
• In-line serviceable – simplified maintenance without pipeline removal
• Modular/flexible design – easy addition of options
• Y-pattern or angle wide-body – minimized pressure loss
• Semi-straight flow – reduced turbulence
• Stainless-steel raised seat – cavitation damage resistant
• Obstacle-free full bore – reliable flow capacity

Typical Applications

• Check valve for pumping and booster stations
• Prevention of backflow and reduction of surge in uphill and vertical pipelines
• One-way flow assurance in waterworks and industrial water systems
