NOZ-CHEK® High Performance Nozzle-Type Non-Slam Check Valves

Technical Details

DESIGN FEATURES

• Few moving parts — Ensuring valve longevity and proven reliability.
• Axial Flow – Disc and seating configuration give streamlined flow path with venturi effect, resulting in minimal pressure drop.
• Short stroke of spring-assisted disc — Inlet flow velocity moves disc axially with short stroke. In response to flow velocity reduction, a compressed spring initiates valve closure and provides quick response.
• Spring options — Choice of spring affects critical velocity and valve response. Selection is made on engineering evaluation of specific applications. In absence of this data, a standard spring will be provided.
• Anti-rotation device – Secures disc assembly and eliminates the risk of disc rotation
