J-VALVES
ASME B16.34 Double Block And Bleed Valve
Structural Features
Double Blocking Function: The valve is designed with two independent blocking balls, enabling double isolation to ensure the medium in the pipeline is completely cut off.
Bleeding Function: The valve has a built-in bleeding channel, which can automatically discharge the pressure in the valve cavity when the valve is closed, preventing pressure accumulation and ensuring operational safety.
Compact Design: The integrated design reduces installation space and weight, while minimizing potential leakage points and improving the overall safety of the system.
Multiple Material Options: The valve body and valve core can be made of various materials (such as carbon steel, stainless steel, alloy steel, etc.) to adapt to different medium and working condition requirements.
Fire-Safe Design: Compliant with the API 607 standard, the valve can maintain sealing performance even in case of fire, preventing medium leakage and ensuring system safety.
Anti-Static Device: Equipped with a built-in anti-static device, it effectively prevents static accumulation, reduces the risk of fire and explosion, and is particularly suitable for controlling flammable and explosive media.
Low-Leakage Design: Advanced sealing technology is adopted to ensure the valve maintains a low leakage rate during long-term use, meeting environmental protection requirements.
Multiple Connection Methods: Various connection methods such as flange connection and threaded connection are available to meet different engineering needs.
