Val-Matic Silent Check Valves from HMA Flow & Industrial feature silent operation, proven performance, and are cost-effective.

Features include:

• Heavy-duty spring: Cycle tested over 100 000 times to ensure valve dependability and non-stem closure.
• Metal-to-metal seating for durability and extended life. Corrosion-free seat and disc sealing surfaces are precision-machined flat and smooth to meet AWWA and MSS metal seat leakage criteria.
• Expanded flow area: Tear-drop contour reduces head loss and provides energy-savings.
• Double guided disc: Prevents vibration and wear, ensuring long valve life.
• Resilient seat: Provides zero leakage. Standard on threaded style, and available on wafer and globe styles.
• Short stroke: The combination of short stroke and spring return assures non-slam closure.
• Mateability: Globe style sizes 2½ through 10 inch mate to wafer-style butterfly valves without the use of spool pieces.
• Concave disc: Concave to flow direction, providing for disc stabilisation, maximum strength, and a minimum flow velocity to open the valve.
