Product Overview
· Total length compliant with ASME B16.10: A truly double-truncated isolation (improving safety) can be used instead of a single isolation ball valve without expensive pipe modifications.
· Single-body threaded end insert: Provides the most compact overall length and reduces potential leakage points to an absolute minimum.
· Full diameter design: Valves provide full diameter dimensions that comply with API 6D standards to ensure maximum flow for productivity and allow pipe cleaning operations.
· Multiple drain valve options and connection methods: A variety of drain valve options and connection methods can be provided according to customer needs.
· Floating ball design:
o Floating ball construction ensures maximum weight and space savings while providing reliable and secure isolation up to and including ASME Class 2500 rating.
o A maximum of 3 inches (approximately 76.2mm) full diameter and 4 inches (approximately 101.6mm) shrinkage specifications are available.
o Comply with ASME B16.10 standard length (CSL).
o Oliver standard length (COSL) is also available.
o The floating ball is designed with a solid lever operating mechanism.
o Flange connection complies with ASME B16.5 standard.
o Integrated drain valve with threaded outlet connection.
Reliable Isolation and Safety: Double-blocking Bleeding (DBB) valves provide true isolation, ensuring maximum safety by preventing leakage between the isolation sections.
Compact and efficient design: These valves provide space-saving solutions, integrating two separate ball valves into a compact body for easy installation.
Designed for harsh environments: Our DBB valves are designed for high pressure applications and can operate reliably in extreme conditions, reducing maintenance needs.
