● Low Torque Floating Seat: The valve uses a floating seat with O-ring seals for easy and efficient bidirectional sealing. It requires only half the usual operating torque, making it easy to open and close.
● Dual PTFE and Metal Seals: The seat incorporates a PTFE sealing ring for dual protection with both PTFE-to-metal and metal-to-metal sealing capabilities. It also helps clean debris from the gate.
● Grease Injection for Sealing: Equipped with a grease valve, the valve allows grease to be injected directly to the seal, achieving zero leakage.
● Flow Guiding Hole Design: The gate includes guiding holes to protect the sealing surface from media erosion, ensuring a perfect seal at all times.
● Low Flow Resistance and Pigging Capability: With a straight and smooth channel when fully open, the valve offers minimal flow resistance and supports pipeline pigging.
● Easy Maintenance and Low Leakage: Features a self-sealing packing structure that requires minimal adjustment and has an auxiliary sealing grease injection for guaranteed zero leakage.
● Self-Relieving Seat: Automatically relieves high pressure inside the valve when closed for added safety.
● All-Weather Actuator: Comes with fully enclosed, weather-resistant actuators suitable for all conditions.
● Position Indicator: Includes an indicator to show whether the valve is open or closed.
● Reliable Seat Design: Features a dual soft seal structure and multiple sealing rings for enhanced reliability.

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 higher than those of cast steel parts. The diameter of forged steel stop valves is generally not more than DN80, and most of them are reduced-diameter designs. Compared with cast steel stop valves of the same diameter, the flow rate is slightly lower, but the pressure and temperature range they can withstand are higher than those of cast steel valves, and their sealing performance is much better than that of cast steel stop valves, and their service life is longer. Like other stop valves, they are subject to the restrictions of the flow direction of the medium. Forged steel stop valves can be divided into straight-through stop valves (type stop valves) and direct-flow stop valves (Y-type stop valves) according to installation positions.
RAYS manufactures high-quality fully welded ball valves, forged from premium materials with side-mounted balls. The valves are available in two designs: cylindrical and spherical fully welded bodies. RAYS is particularly known for its cylindrical valve bodies.
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
