● Excellent fire and flame retardant performance: The valve is made of high-quality stainless steel, brass or Monel alloy and other materials, with good flame retardant and electrical conductivity.
● Oil-free design and cleaning requirements: All components are strictly degreased during the manufacturing process to ensure that there is no oil, the surface is smooth and no burrs, and the high cleaning standards for oxygen delivery are met.
● Compact structure, safe and reliable: the valve has compact design, fast heat transfer, easy operation, excellent sealing performance and long service life.
● Low torque operation: Valve with low torque design, flexible operation, reduce mechanical friction, reduce the risk of ignition.
● Fire safety Certification: compliant with API 607 and API 6FA fire safety standards.

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.
The Axial Flow Check Valve has a unique axial flow design, and its spool is aligned with the flow direction, significantly reducing the resistance loss when the fluid passes through. The spool is driven by spring or fluid pressure for quick opening and closing. When the fluid is flowing forward, the spool is pushed open and the fluid passes smoothly. When the fluid flows in reverse, the spool is quickly closed, effectively preventing backflow, and ensuring the stability and safety of the system operation.
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.
