● Sealing Efficiency: Equipped with lip-type seal seats for excellent sealing, low friction, and minimal operational torque.
● Stem Safety: Features a bottom-mounted stem to prevent blowout and maintain seal integrity during fires.
● Fire and Static Safety: Includes fire-safe and anti-static features, suitable for soft-sealed valves.
● Accurate Handle Indicator: The flat-headed stem ensures that the handle's position accurately reflects the valve's status.
● Locking Mechanism: Locking holes at fully open and closed positions prevent accidental operation.
● Design Benefits: These valves are quick to operate, compact, lightweight, easy to maintain, and work smoothly with minimal fluid resistance and noise.

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.
RAYS cast steel check valves are designed and manufactured to provide maximum service life and dependability. All check valves meet the design requirements of American Petroleum Institute standard API600 & 6D.BS EN 13709 and generally conform to American Society of Mechanical Engineers standard ASME B16.34. Valves are available in a complete range of body/cover materials and trims.
RAYS C-type ball valve adopts a double eccentric design: the rotational center (axis) of the C-ball is offset from both the geometric center (sphere) of the C-ball sealing surface and the sealing center of the seat. This double eccentric design results in a dual-vector cam motion involving both rotation and translation of the C-ball, facilitated by the stem being offset in two planes. When the valve is closed, the C-ball and the seat interact to create a cam-action wedge tightness, achieving a torque seal. The torque required for sealing is provided by a handle, gear, or actuator, ensuring a tight shut-off that is mechanically independent of springs or process pressure
