The dual plate check valve features two semicircular, spring-loaded valve discs mounted on a central vertical pivot. When the valve opens, the force of the fluid and the spring act at the center of the disc, causing it to open from the base first. This design minimizes wear on the seal during opening, enhancing its durability. As the flow decreases, the discs slowly move back towards the seat due to the spring's force, ensuring a gradual closure. During backflow, the increased force on the discs leads to a faster closure, effectively reducing the risk of water hammer and hydraulic shocks. The spring’s force closes the top end of the disc first, preventing damage at the disc's base and prolonging the seal's lifespan.
RAYS pig valve is a high-performance ball valve designed for severe industrial environments, featuring multifunctionality aimed at optimizing pipeline cleaning and maintenance. This valve facilitates the movement of pipeline pigs to effectively remove scale, deposits, and other impurities, maintaining cleanliness and flow efficiency in pipelines.
RAYS Through Conduit (T.C.) Slab Gate Valves are manufactured with a full bore port, rising stem OS&Y and with floating seats and gate, pressure energized, for a bubble tight shut off upstream and downstream under both low and high differential pressure. Double block and bleed capability and automatic relief of excess body pressure are a standard feature of this seat design. The smooth, continuous bore minimizes turbulence within the valve and when in the open position it produces a pressure drop equivalent to a portion of pipe of the same length and diameter. The seat faces are outside the flow stream and therefore protected from the erosive action of the flow. Pigs and scrapers can be run through the valve without damage.
