Hy-Lok USA Introduces Customizable Double Block and Bleed Valves
Hy-Lok USA has expanded its instrument valve product line with Double Block & Bleed Valves that can be designed and engineered to order. Double Block & Bleed Valves, also known as DBB isolation valves, provide an alternative to multi-valve systems by combining typical block and bleed components into a compact, space-saving unit.
Hy-Lok double block and bleed valves are integrally forged, one-piece assemblies used for the primary isolation of pressure take-off and process flow. Double Block and Bleed Valves reduce the need for costly multi-valve systems, minimize potential leak paths, and provide significant weight savings.
“With the space-saving requirements of off-shore oil and gas extraction, it was important to offer a compact valve that is highly versatile,” said Jody Barnes, CEO of Hy-Lok USA. “Our DBB valves are flexible in design, and can be engineered to meet custom lengths, heights, and connection sizes.”
The DBB valves’ compact design is ideal for instrument isolation chemical injection, gauge isolation, oil and gas production, and direct or remote mounting of instruments. Customers have the option of choosing from a large inventory of ready-to-ship DBB valves or custom designing a solution that is optimized for their particular system.
Additional double block and bleed valve benefits include uninterrupted flow for negligible pressure drop, low maintenance requirements, and a smaller profile for reduced risk of vibration damage. Optional DBB features include probes, check valves, seat wipers, and injection quills.
Double block and bleed valves are available in modular, monoflange, and root configurations, and can be fitted with optional one way check valves for chemical injection applications. DBB valves meet ANSI/ASME design standards and are quality assurance tested to meet ISO 9001 standards.
