VAL-MATIC Silent Check Valve
Val-Matic silent check valves are preferred over other check valves where noiseless operation and cost are crucial concerns. These silent check valves are essential in centrifugal pumps and HVAC systems to check backflow without noise. Their short stroke and spring-assisted closure make them th...e fastest closing check valves.Read more

Silent Check Valve
Val-Matic general-purpose check valves are designed with an inline silent body ideal for use with potable water and vertical-flow applications requiring a high head. These non-slam check valves come equipped with a spring, tested for over 100000 cycles, to eliminate the water hammer effects (high-pressure shock waves) caused by abrupt pump shut down or closing of the valve disc. Val-Matic check valves feature a short linear stroke and a spring return action that works together to close the valve before the flow reversal, and an expanded body with a fast closure mechanism for providing a full-flow area. They also have a metal-to-metal seating facility and a double-guided disc for high precision and reducing the vibrational loads, respectively. Val-Matic check valves are NSF/ANSI 372 certified for including lead-free components and NSF/ANSI 61 certified for use with drinking water.
Working Mechanism
- When the flow occurs, the valve disc lifts off the seat to allow forward flow.
- When the pump stops, the spring in the valve forces the disc to close before flow reverses.
Features
- Val-Matic silent check valves have heavy-duty springs to ensure valve dependability.
- They have metal-to-metal seating for durability and extended life.
- These valves have a short stroke and spring return to assure non-slam closure.
- They have a double-guided disc to prevent vibration and wear to ensure long valve life.
- Val-Matic silent check valves withstand water pressures up to 200 psi.
Standards and Approvals
- NSF 372
- NSF 61
- FM
- MSS-SP 125
