Why Choose Hy-Lok for your Integral Double Block and Bleed Valve’s

Integral double block and bleed valves are essential in the oil and gas industry, onshore terminals, control panel manufacturers and compressor manufacturers. The double block provides a seal from both ends of the valve to isolate the upstream fluid flow in the system from reaching other components of the system that are downstream.

Hy-Lok’s integral double block & bleed valves are engineered to offer compact installation for gauge or transmitter instruments to provide minimum leak path and reduce the risk of damage from vibration. Read on to learn more about Hy-Lok’s Integral Double Block and Bleed Valve.

The Benefit of Hy-Lok’s Valve

This design allows for fewer leakage points, minimal effects on system vibrations, and reduced installation costs. With Hy-Lok’s integral double block and bleed valve, supporting brackets are no longer required.


Integral double block and bleed valves can be used for several applications such as sample connections, gauge isolation, instrument drain, chemical seal instrument isolation and more! The valves are made from stainless steel and can withstand maximum operating pressure of 10,000 psi at 100 Fahrenheit.
