I. Product Overview
NWV electric-actuated globe valve with manual override is a dual-operation industrial valve engineered for precise flow control and shutoff in critical pipelines. Featuring a stainless steel globe-style body, it integrates an electric actuator for automated process control with a manual handwheel for backup or local operation. Compliant with industrial standards (DIN, ASME), this valve ensures reliable performance in applications involving water, steam, oil, and mild chemicals—ideal for petroleum, chemical processing, power generation, and municipal systems where automation and fail-safe manual control are essential.
II. Key Attributes and Specification Parameters
Basic Attributes
Structure Design: Globe valve with a straight-through flow path; the disc seals against the seat for flow regulation. Combines an electric actuator (rotary or linear motion) with a manual handwheel for dual operation.
Body Material: Stainless steel (304/316) for corrosion resistance in aggressive media; optional cast steel (WCB) for general industrial use.
Sealing System: Metal-to-metal sealing (hardened alloy seats) for high-temperature durability or soft sealing (PTFE) for bubble-tight shutoff. Flexible graphite packing prevents stem leakage.
Pressure Rating: PN16 to PN100, Class 150 to Class 600, suitable for low to high-pressure systems.
Temperature Range: -29℃ to 425℃ (stainless steel), accommodating cryogenic to high-temperature media like steam or hot oil.
Nominal Diameter Range: DN15 to DN300, covering diverse pipeline sizes.
Connection Type: RF flange per ASME B16.5 or DIN EN 1092-1, ensuring compatibility with global pipelines.
Operation Mode: Electric actuation (AC/DC power, with control modules for position feedback) and manual handwheel override for emergency or maintenance use.
Media Compatibility: Water, steam, oil, gas, and mild chemicals; stainless steel variants suit corrosive media.
Design Standards: Complies with ASME B16.34, DIN EN 12266, and API 600, meeting international quality norms.
