Tilting Disc Check Valve - Cast Steel | Neway

Neway Cast Steel – Tilted Disc Swing Check Valve

The Neway Cast Steel check valve is a swing/swivel disc type, designed for industrial pipelines where reverse flow prevention is required without an actuator. Operation is achieved via process flow and disc gravity. Product data indicates a range of NPS 2"–48" / DN50–DN1200 and pressure ratings ASME Class 150–4500 / PN16–PN760.

Construction and Connections

• Body materials: carbon steel, stainless steel, alloy steel, duplex stainless, low-temperature steel, nickel base, or titanium alloy.
• Ends: RF, BW, RTJ.
• Check valve design: API 594, bolted cover, swivel disc in cast carbon steel versions.
• Available classes: Class 150, 300, 600, 900, 1500, 2500.

Standards

Face-to-face / end-to-end dimensions per BS EN 558, BS EN 12627, ASME B16.10, or ISO 5752. Flanges per ASME B16.5 / ASME B16.47, BW ends per ASME B16.25. Testing per API 598 or BS EN 12266.

Trim Materials

Standard trims include WCB, LCC, WC9, and CF8M. Seat rings: A105 or F316 with Stellite overlay, depending on service. NACE-compliant trims available for sour service.

Applications

Suitable for steam, boiler feedwater, condensate, hydrocarbons, thermal fluids, and compatible process gases or liquids. Valve selection should consider pressure-temperature rating, corrosion, fluid phase, flow velocity, and seat leakage requirements.

FAQ

Installation orientation?
Horizontal installation for liquids, or vertical installation with upward flow, as per datasheet.

When is special consideration required?
At low flow rates, large diameters, pump stations, or lines prone to water hammer, as disc movement must be stable to avoid seat impact.
