Triple offset butterfly valves (TOV) are a type of industrial valve used for fluid control applications. They feature an oblique sealing disc and three concentric seals that create tighter seals and lower operating torque than other types of valves, such as ball, gate, or metal seat designs. This article will explore the advantages of this type of valve, how it works, and its major applications.

Geometric Design

A triple-offset butterfly valve is a highly efficient, durable, and low-maintenance option for a wide variety of processes. Its cam action and right-angled conical design ensure that the seal components will not come into contact until their final degree of closing, enabling repeatable, leak-proof performance and significantly extended valve life. In addition, the absence of cavities between the seal components eliminates clogging, reducing maintenance requirements and the overall cost of ownership.

The first offset is located in the centerline of the valve body, where it becomes the axis of the seat cone angle. This angled positioning of the valve disc prevents seat damage, maintains the integrity of the sealing surface, and reduces operating torque.

The second offset is located in the centerline of the shaft, which enables the valve stem to be centered over the cone angle. This allows the valve to open and close quickly and provides for easier operation and lower operating costs compared with other valves such as gate or ball valves. Additionally, the top-entry design makes it easy to inspect and replace the valve seat ring without shutting down the pipeline or requiring any special tools.

As threats to people and buildings increase from criminal acts and terrorism, security measures become more sophisticated. Bollards are a versatile solution to thwart hostile vehicle attacks (HVM) by acting as both visual barriers and physical protection from vehicles. Whether they’re used as standalone applications or covers for steel-and-concrete security posts, these durable and attractive designs allow for access while deterring vehicles from entering sensitive areas. They’re available in multiple sizes and styles that meet different security ratings, as well as illuminated and non-illuminated options.

Traditional Bollards security are typically made of cast iron, and provide a timeless aesthetic that blends with most architectural settings. They’re a popular choice for regulating traffic in urban centers and public spaces, preventing vehicular intrusion and controlling access during specific hours. They can also be used in private parking areas, as a barrier for underground garages, and to protect high-profile buildings from attacks.

For a more modern approach, retractable bollards raise to prevent vehicle entry and then slide back into their ground receivers to permit passage. These are ideal for areas where a temporary blockage is needed, such as during events or during construction. They’re also a common replacement for lift gates at access points like parking garages or rail crossings.

For the highest levels of security, crash-rated bollards are designed to withstand multiple waves of vehicle attack. These are often used in governmental facilities and buildings to guard against terrorist attacks. They’re installed far enough from the building to prevent penetration and create a safe distance for people to evacuate in the event of an incident.

Order Weed Online

As the cannabis industry continues to grow and expand, consumers are getting more and more comfortable with purchasing their favorite products from a website rather than going to a storefront. Cannabis delivery services exploded during the COVID-19 pandemic, and they haven’t shown any signs of slowing down as more and more states pass laws to legalize marijuana for both medical and recreational use.

In some states, ordering weed and other marijuana-related products online is as simple as purchasing anything else from an online retailer like Zara or Amazon. Simply locate your preferred shop and browse through their inventory, add items to your cart and hit checkout. Then sit back and wait for your package to arrive.

However, if you’re purchasing from a dispensary that sells marijuana (or anything else that’s illegal on the federal level), you might need to jump through a few extra hoops. For example, most dispensaries require that customers purchase their weed using an e-transfer instead of credit card payments because banks and credit card payment processors don’t view pot as a legitimate commodity.

You can find a variety of online ordering options by using tools like Weedmaps or Leafly to locate nearby retailers that offer both delivery and pickup services. Once you’ve located the desired retailer, browse their online menus to compare prices and look for strain information and typical effects to help narrow down your selections. Then when you’re ready to check out, confirm your address, age and any other applicable information then complete your purchase by submitting your photo ID.
