NWV’s WCB pneumatic actuator flat parallel sliding gate valve is specially designed for automated fluid control in industrial scenarios such as petroleum, chemical, and water treatment.

NWV API 6A forged gate valves are precision-engineered for critical oil and gas well applications, adhering to American Petroleum Institute standards.

NWV GB/API standard flanged slab gate valves are engineered for industrial fluid systems, constructed from cast steel (WCB/WCA) or stainless steel (304/316), compatible with GB/T 12234, API 6D, and other international/domestic standards.

NWV manual flat gate valves are designed for precise flow control in industrial pipelines, adhering to GB/T 12234 standards. Featuring a flat gate design and flange connection, these valves are crafted from high-quality carbon steel (WCB) or stainless steel (304/316).

NWV flanged bevel gear cryogenic gate valves are engineered for low-temperature applications, featuring cast steel (WCB/LCB) bodies and bevel gear drives. With extended stems and thermal insulation, they resist cryogenic media erosion.

NWV zero-leakage direct-buried flat plate gate valves are specially designed for underground pipeline systems, featuring fully sealed buried structures to eliminate space occupation and external damage of surface-mounted valves.
