Silent Check Valve(8 Products)
VAL-MATIC

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.

• 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.

• 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.
