The DIN 3202 F7 PN64 Cast Steel WCB Gate Valve is a high-pressure powerhouse. Built for extreme conditions, the F7 standard specifies a "Long Pattern" face-to-face length, while the PN64 rating allows it to handle pressures up to 64 bar.
Constructed from ASTM A216 WCB, it features a rising stem (OS&Y) and a flexible wedge for superior sealing in steam, oil, and gas. It is the go-to choice for power plants and heavy industrial pipelines requiring high safety margins.
