  • Rapid, non-slam closure during pump shutdown

  • Optional position feedback for SCADA integration

  • Ideal for sewage lift stations and raw water intakes

Designed for high-capacity systems, APCO Swing Check Valves offer automatic, gravity-assisted closure to prevent reverse flow. These valves are ideal for clean water and moderate solids, with low head loss and silent operation when paired with dashpots or lever & weight assemblies.

  • Available in flanged, rubber-seated, or metal-seated designs

  • Optional spring, lever & weight, or dashpot for controlled closure

  • Sizes from 2"–72"

Perfect for wastewater, sludge, and raw water applications, rubber flapper check valves use a molded elastomer flapper for silent, corrosion-resistant operation. Their full flow opening and low pressure drop make them a popular choice for treatment plants.

  • Flexible, corrosion-resistant design

  • Compact footprint for tight spaces

  • No hinge pins or metal-to-metal contact

These non-slam, spring-assisted valves are engineered to reduce surge and water hammer in high-velocity systems. The slanting disc design promotes quick closure and high flow efficiency.

  • Ideal for pump discharge in water and sewage systems

  • Spring-loaded for fast shutoff

  • Silent operation without slam

Compact, lightweight valves designed for tight spaces and horizontal or vertical installations. Their dual spring-loaded doors close quickly to minimize backflow and slam.

  • Dual disc design for fast, even closure

  • Available in cast iron, ductile iron, stainless, and bronze

  • Sizes up to 72"

Used in clean water systems, APCO silent check valves feature a center-guided, spring-assisted disc for quiet, dependable operation. Common in commercial buildings, water mains, and booster stations.

  • Center-guided design prevents valve chatter

  • Quick closure for surge control

  • Excellent for potable water

APCO Full flow foot valve (FFF)

Heavy-duty foot valves designed for clean water applications requiring full flow and minimal head loss. These valves prevent backflow and protect pump suction lines from debris entry.

  • Center-guided disc ensures stable, low-resistance flow

  • Horizontal or vertical installation versatility

  • Available in sizes from 2"–36"

Built for clean or dirty water systems, these rubber flapper foot valves provide corrosion-resistant, self-cleaning closure for pump suction lines.

  • Resilient flapper design eliminates hinge pins and metal-on-metal wear

  • Excellent for wastewater and sludge applications

  • Sizes available from 3"–24"

DeZURIK’s Hilton line includes custom-engineered check valves for specialized applications. All designed for critical flow control in large-diameter or unique piping systems. The Hilton H-900 Angle Disk Check Valve is designed for vertical installations with severe flow conditions, using a compact, angular body that provides minimal head loss and fast, non-slam closure. Engineered for critical flow control, the Hilton H-940 Tilting Disc Check Valve provides quiet, non-slam closure with a center of gravity–balanced disc that reduces water hammer in high-velocity systems.

The H-920 Wafer Swing Check Valve features a low-profile, lightweight design ideal for tight piping configurations, offering efficient backflow prevention in clean and lightly contaminated systems. The H-950 Fabricated Swing Check Valve offers a heavy-duty solution for large-diameter piping and custom system needs, with options for external levers, weights, or dashpots to tailor closure control.
