F4 gate-valve offering described as a German-standard resilient-seat form.
The Botou company’s catalog names an F4 resilient-seated gate valve in its German-standard range. The F4 reference is a starting point for dimensional matching, not a complete procurement specification. Supply the required nominal size and mating flange information, and confirm the applicable dimensional standard, elastomer and pressure-temperature schedule for the offered valve.
