The Alloy Valves and Control (AVCO) Series 1100 is a high performance ball valve that is designed and engineered in a three-piece construction. It is able to handle a wide array of fluid flow conditions due to its versatility of interchangeable components; while still meeting or exceeding industry standards. It provides the ability to engineer new features and services to the valve to meet different specifications or increase the operational cycle life.
This advanced engineered product has a floating ball design in the cavity of the valve body which is independent from the stem (not integral). It has the ability to seal bi-directionally when pressurized. The ball is fully spherical and machined full port to meet a high coefficient flow without restriction to the flow. In case of over pressurization due to thermal expansion in the cavity of the ball or the orifice, the ball is slotted or vented for relief on the upstream side of fluid flow. This quarter-turn valve is designed to meet vacuum service, high pressure and the ability to meet cryogenic to high temperature services.
AVCO is continually improving this series by developing and engineering quality components, making the final product even more efficient and reliable as manufacturing and material enhancements allow. The development of the encapsulation of the seats and body seals with stainless steel retainers is just one feature of this valve. In case of a fire, the retainers act as a back-up seat while the valve is in the closed position. The body bolts are fully enclosed in the cast body to allow chemical wash downs, eliminating any corrosion on the bolts due to the harsh effects in a corrosive environment. The valve is designed to meet ASME 16.34, 2009 standards and conforms to API 607 4th edition, as well as pressure class ASME 600 and below with bubble tight shut-off.
The valve design allows for interchangeability of seats, seals and packing options in materials of polymer, elastomeric and cobalt alloy (metal). This mixture of material handles a wide array of corrosive media, temperature, pressure fluctuation, velocity and abrasiveness. These sealing materials ensure leak-proof shut-off and are used in a variety of alloys offered by AVCO. The valve bodies and balls are available in WCB Carbon Steel and CF8M Stainless Steel as standard and when higher strength alloys are needed to fight against erosive-corrosive media, CN7M Alloy 20, CW-7M Hastelloy C and Monel 400 are part of AVCO’s exotic alloy offering for the alloy market.
Modern processes controlled by computers, programmable logic controllers or other electric or pneumatic control equipment, are able to communicate to our devices by mounting hardware to the valve’s ISO 5211 mounting pad for actuation packages. The types of actuators that are used with this product include pneumatic, electric or manual design for on-off or modulating control applications. The ISO 5211 mount pad also allows the valve to be adapted for bolted-bonnet assemblies such as the Fugitive Emission and Cryogenic bonnets for certain types of services.
AVCO is proud to offer this high performance valve during the 21st Century innovation and will continue to meet and exceed expectations for all fluid flow conditions. With high quality machining, testing and complying with agencies such as ASTM, the 1100 series is a proven leader and a reliable product for the industrial market for years to come. Thank you for choosing the AVCO series 1100.
