● Frictionless Switching: The unique design prevents friction against the valve seat, reducing wear compared to traditional valves.
● Single Seat Design: This design ensures no leakage downstream and prevents pressure build-up inside the valve.
● Self-Cleaning: The media flows 360 degrees around the seal when the valve core moves away from the seat, cleaning off any debris.
● Low Torque Required: Without friction on the sealing surface, the valve turns easily.
● Durable Hard Seal: The valve core's sealing surface is reinforced with hard alloy, making it reliable even in harsh conditions.
● Double Eccentric Design: This feature combines the best aspects of various valves, handling extreme conditions like high and low
temperatures, frequent operation, and bidirectional shutoff more effectively.
● Full Bore Design: The design ensures an open, unobstructed flow path without any dead zones or build-up, eliminating the need for
pressure relief.

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.
There are two main types of forged steel check valves: forged steel swing check valves and forged steel lift check valves. The quality of forged steel parts is higher than that of cast steel parts, and they can withstand large impact forces. Their plasticity, toughness, and other mechanical properties are also higher than those of cast steel parts.
