Double Door Check Valve - Axial Flow Check Valve – Newsway

Axial Flow Check Valve

Axial flow

Streamlined flow path through full-port expanded body avoids turbulence and prevents erosion and vibration. Process downtime and maintenance costs are eliminated. Intelligent use of venture results in static and dynamic performance, axial flow check valve has become the preferred choice for special applications.

Design

Valve design to API 6D/ASME B16.34.

All valves are available with any international flange standard.

Low pressure drop

The full opening flow passage and high-pressure recovery of the venturi-shaped body result in very low pressure loss: reduced operating cost of pumps and compressors.

Horizontal/Vertical installation

Unlike most traditional swing check valves, NEWSWAY VALVE COMPANY axial check valves are ideal for both horizontal and vertical pipeline installation.

Maintenance Free

The NEWSWAY VALVE COMPANY Axial Flow Check Valve designs use no soft parts and therefore inherently fire-safe. Various other non-return valve designs rely on external devices like counterweights and slam retarders to operate satisfactorily. Those do not allow buried installation, are space consuming and require regular maintenance. The NEWSWAY VALVE COMPANY Axial Flow Check Valve can be buried or installed in locations where space or weight is at a premium. The NEWSWAY VALVE COMPANY Axial Flow Check Valve normally does not require maintenance.

Newsway Valves Materials

NSW valve body and trim material can be offered in Forged type and Casting type. Next to stainless and carbon steel material, we also manufacture valves in special materials such as titanium, nickel alloys, HASTELLOY®*, INCOLOY®, MONEL®, Alloy 20, super-duplex, corrosion resistant alloys and urea grade materials.
