Vapor Recovery Dry Disconnect Coupling

dry disconnect couplingThe OPW 2173AVN Vapor Recovery Dry Disconnect Coupling provides for easy access in recovering vapors for either top or bottom loading/unloading tank truck operations. The OPW 2173AVN Dry Disconnect Coupling installs onto the QRB valve on tank trailers and can provide a dry disconnect connection for emergency evacuation of hazardous liquids in the case of roll-over.

Benefits
•    Closed-Loop Protection – Helps protect people and the environment by providing a vapor and liquid tight seal during the connection / disconnection process specifically designed to contain VOC (Volatile Organic Compounds) products that have high vapor pressure that evaporates quickly. Contains fugitive emissions and transfers VOC’s without vapor loss.
    •    Roll-Over Safety – Its low profile design keeps the fitting below roll-over plane to minimize damage in the event of a roll-over. Meets IMO profile dimensions.
    •    Easy Emergency Evacuation – Provides a dry disconnect connection for emergency evacuation of hazardous liquids in case of roll-over.
    •    Quick and Easy Cleaning – Designed for easy disassembly for periodic routine cleaning.

Features
    •    Vapor Hose Connection – 2″ Kamvalok® Dry Disconnect Coupling or D2000™ Actuating Couplers.
    •    No trailer modifications required – Easy attachment to existing MC307, DOT407, MC312, and DOT412 trailers.
    •    The 3″ straight thread mounting with 2″ dry disconnect cam and groove connection makes the ideal 3″ x 2″ adaptor for any QRB valves.

Truck Loading Arms

truck loading armsWe carry only top of the line OPW truck loading arms for our customers. OPW Engineered Systems custom-designs and manufactures truck loading arms for specialized applications. With their extensive experience it’s likely their engineers have already solved most situations you may encounter. However, with the many varying factors that impact fluid dynamics, there are no hard-and-fast rules for determining exactly what type of loader must be used in each installation. Personal preference, operating experience and methods, safety requirements and local customs all warrant consideration.

When needing truck loading arms designed for your unique application, the following things are taken into consideration:

•    Temperature and pressure of liquid product to be handled
•    Type of tank or container that will be used
•    Flow rate
•    Adequate capacity without excessive pressure drop
•    Physical facility dimensions and limitations
•    Adequate horizontal and vertical range
•    Ease of operation
•    Ease of maintenance
•    Special requirements
•    Cost of design and manufacturing

Within the limits of design and functionality, nothing is too special. As industries have become more aware and responsive to environmental issues, loading systems offer a sound solution to the extremely critical process of transferring hazardous products from bulk storage tanks to rail or road vehicles.

All units can be factory pre-assembled and tested, and all OPW Engineered Systems products are built to the highest quality standards.

Leak-Proof Sight Flow Indicators

sight flow indicatorsUsing sight flow indicators you can efficiently and effectively visually monitor the flow of fluids to determine where, if any, problems exist at certain points along the industrial process line. These inexpensive, relatively simple devices are installed directly in the process line and allow operators to observe flow rate, direction, color and clarity through a glass viewing lens.

We offer a complete line of sight flow indicators, including the popular VISI-FLO® series by OPW. These indicators provide a quick, reliable way to monitor fluid lines. Available in a variety of sizes, styles and materials for a wide range of industrial applications, all OPW sight flow indicators are tested to 1-1/2 times rated pressure to ensure maximum reliability in a variety of conditions.

sight flow indicatorsThe complaint most often registered against sight flow indicators is that they leak, principally due to the failure of the conventional flat seals many use. VISI-FLO® is guaranteed not to leak for three full years under normal use. The key design attributes that enable innovative radial sealing design is so good, it’s guaranteed not to leak!

The unique bolt-on design fastens the face plate assembly directly to the body without any special torquing sequence. This provides quick access to the unit from the front side, which gives companies the flexibility to install VISI-FLO® in locations where other sight flow indicators are unable to be installed due to clearance problems.

Versatile Uses for Swivel Joints

swivel jointsOur swivel joints have a broad range of uses in the chemical, petrochemical, petroleum, refining, distilling, mining, brewing industries, as well as farm fertilizing and irrigation. Design, plant and maintenance engineers use swivel joints in flexible piping systems, loading arms, hose reels, sewer rodding and wastewater treatment applications, and various types of process machinery. Our swivel joints are also used in machine tool coolant transfer, drum filling applications, and in a variety of in-plant fluid and dry bulk transfer applications.

Versatility is the key to swivel joints. They make it possible for you to use rigid metal piping for loading and unloading fluids and dry product under pressure or vacuum without the difficulty or danger of handling heavy, cumbersome hoses. A swivel joint can feature combinations of five metals and five seal materials to meet most material handling requirements. They can also be custom designed to conform to your special specifications.

For applications where a hose is necessary, swivel joints mounted at the end of the hose eliminate kinking and twisting, and reduce hose wear. Fitted to metal frameworks and attached to hoses, the joints can guide the hose more easily and keep uncontrolled hose from kinking and denting or scratching tanks, trucks, and other equipment

In the fields of petroleum, chemical, refining, mining, distilling, brewing, and more there are hundreds of applications requiring the use of a ball swivel joint. These piping components rotate 360 degrees and permit the use of rigid metal piping for loading and unloading hazardous chemicals, petroleum, and other materials without the danger of handling cumbersome hoses.

Transmitting Power with Couplers

couplersCouplers are extremely useful components in many industries. They are used to connect the ends of two shafts together in order to transmit power. Positive couplers can assist in transmitting rotary power from one shaft to another, where both shafts turn. The use of couplers permits some degree of misalignment or end movement.

There are many categories of shaft couplers and each of the different types have specific applications.

Rigid couplers. When there are requirements for the precise shaft alignment, the rigid coupler is used. There are also variations of this coupler such as the flange coupler and the muff coupler.
Torque limiting couplers. Can protect systems against conditions of over torque.

Flexible couplers. One function of this coupler is connection of a driving shaft or flange element with an adjacent in-line driven member. It must flex enough while rotating to accommodate, within limits, undesirable effects caused by axial misalignment, shaft end movement, and vibration between connected members. This kind of coupler can also be further divided into many other types (universal coupler, bellows coupler, disc coupler, jaw coupler, and gear coupler.

We carry Kamvalok® couplings, a dry disconnect which helps eliminate dripping before, during, and after loading, and Dry Lok couplers, the closest dry disconnect on the market. It features low pressure drops, along with very tight seal, allowing virtually no spillage.
