Chemical processing has many ins and outs, and when it comes to efficiently operating your equipment, the small details matter. Essential components like fittings, valves, and connectors are often the key factors that influence whether your equipment remains operational or creates a potential safety issue.
Block and bleed valves are indispensable chemical processing components that prevent chemical contamination, equipment failure, and other hazards. Keep reading to learn more about these useful components and why Hy-Lok is Canada’s go-to choice for a quality bleed valve.
What Are Block and Bleed Valves, and What Do They Do?
Block and bleed valves are important components in several industries, including oil and gas, power generation, and chemical processing. Most valves are designed to control the flow of liquid and gas in hydraulic and pneumatic systems, while block and bleed valves are designed to isolate fluid from equipment during maintenance and repairs without interrupting the equipment workflow. These valves are generally used in tandem with manifolds or gauge/root valves to vent signal line pressure into the atmosphere.
In chemical processing, block and bleed valves are used to control hazardous or flammable liquids and gases that, without the depressurizing mechanism this component provides, can be a safety hazard for equipment operators.
The Role of Block and Bleed Valves in the Chemical Industry
Block and bleed valves play a crucial role in the chemical processing industry. Their double barrier provides a safe transfer for hazardous chemicals from their reservoir to their final destination, without the risk of leaks or contamination.
Block and bleed valves can be manufactured with corrosion-resistant materials, like our 316 stainless steel valves from Hy-Lok. This ensures that they can be used to transfer even the harshest chemicals without damaging the valve and other components.
By installing a double block and bleed valve in your chemical processing equipment, you can also reduce the number of separate valves and components usually required. This offers more efficiency and productivity with reduced installation times and potential leak points.
Why Get a Bleed Valve from Hy-Lok
If your chemical processing plant requires block and bleed valves for its operations, Hy-Lok offers the highest-quality, ISO, API, and ASME-certified components. Our bleed valves are 100% factory tested with nitrogen at 1000psig to a maximum leak rate of 0.1 SCCM. We also perform a hydrostatic shell test at 1.5 times working pressure, and can provide other tests upon request.
Other features of our block and bleed valves include:
- Pressure ratings up to 10,000psig at 100°F (37°C)
- Temperature ratings from -65°F to 850°F (-54°C to 454°C) with stainless steel, from -20°F to 450°F (-29°C to 232°C0) with carbon steel, and from -65°F to 500°F (-54°C to 260°C) with alloy 400.
- Compatible with a variety of end connectors, including our tube fittings from Hy-Lok, male/female NPT, and ISO/SAE threads.
