The Williams/Cozy 74317-K VALVE MV, model number VS821A1061, is a high-performance, energy-efficient steam trap designed for use in residential and light commercial steam heating systems. This trap is manufactured by Williams Steam and Hot Water Boiler Company, a leading name in the steam industry known for its innovative and reliable products.
The VS821A1061 is a bucket type steam trap that operates by trapping condensate and steam in its bucket, allowing the steam to pass through while the condensate is held back. Once the bucket is filled with condensate, the heat from the incoming steam causes the condensate to flash into steam, which is then released through the discharge pipe. This process repeats continuously, ensuring efficient steam utilization and minimizing the loss of valuable heat energy.
The trap is made of durable materials, including a brass body and a stainless steel bucket, ensuring long-lasting performance and resistance to corrosion. It features a non-clogging, self-cleansing bucket design, eliminating the need for regular cleaning and maintenance. The trap also comes with a built-in bypass valve, which allows for automatic bypass of condensate during periods of low steam demand, further increasing energy efficiency and reducing fuel consumption.
The VS821A1061 is easy to install and can be mounted in various orientations, making it a versatile solution for a wide range of applications. It is also compatible with a wide range of steam heating systems, including hydronic and hot water heating systems. The trap has a maximum working pressure of 15 psig and a maximum temperature rating of 350 F, making it suitable for most residential and light commercial steam heating applications.
In summary, the Williams/Cozy 74317-K VALVE MV, model number VS821A1061, is a high-performance, energy-efficient steam trap designed for use in residential and light commercial steam heating systems. Its durable construction, self-cleansing design, and automatic bypass valve make it a reliable and low-maintenance solution for steam heating applications, while its compatibility with various heating systems and orientations make it a versatile and flexible choice for contractors and homeowners alike.
